Abstract

This guide provides details on using the Thorntail runtime with Red Hat OpenShift Application Runtimes.

Preface

This guide covers concepts as well as practical details needed by developers to use the Thorntail runtime.

Chapter 1. What is Thorntail

Note

Thorntail was formerly known as WildFly Swarm.

Thorntail deconstructs the features in JBoss EAP and allows them to be selectively reconstructed based on the needs of your application. This allows you to create microservices that run on a just-enough-appserver that supports the exact subset of APIs you need. See Additional Resources for further information about Thorntail.

The Thorntail runtime enables you to run Thorntail applications and services in OpenShift while providing all the advantages and conveniences of the OpenShift platform such as rolling updates, service discovery, and canary deployments. OpenShift also makes it easier for your applications to implement common microservice patterns such as externalized configuration, health check, circuit breaker, and failover.

Thorntail has a product version of its runtime that runs on OpenShift and is provided as part of a Red Hat subscription.

Chapter 2. Example applications and cloud-native development on OpenShift

When developing applications on OpenShift, you can use examples to kickstart your development.

Example applications

Examples are working applications that showcase different fundamental pieces of building cloud native applications and services.

The examples implement a Microservice pattern such as:

  • Creating REST APIs
  • Interoperating with a database
  • Implementing the Health Check pattern

You can use the examples for a variety of purposes:

  • A proof of technology demonstration
  • A learning tool, or a sandbox for understanding how to develop applications for your project
  • A starting point for updating or extending to your own use case

Each example application is implemented in one or more runtimes. The REST API Level 0 example is implemented for these runtimes:

Chapter 3. Available examples for Thorntail

The following example applications are available for Thorntail.

3.1. REST API Level 0 example for Thorntail

Example proficiency level: Foundational.

What the REST API Level 0 example does

The REST API Level 0 example shows how to map business operations to a remote procedure call endpoint over HTTP using a REST framework. This corresponds to Level 0 in the Richardson Maturity Model. Creating an HTTP endpoint using REST and its underlying principles to define your API lets you quickly prototype and design the API flexibly.

This example introduces the mechanics of interacting with a remote service using the HTTP protocol. It allows you to:

  • Execute an HTTP GET request on the api/greeting endpoint.
  • Receive a response in JSON format with a payload consisting of the Hello, World! String.
  • Execute an HTTP GET request on the api/greeting endpoint while passing in a String argument. This uses the name request parameter in the query string.
  • Receive a response in JSON format with a payload of Hello, $name! with $name replaced by the value of the name parameter passed into the request.

3.1.1. Viewing the example application source code and README

Prerequisites

One of the following:

  • Access to developers.redhat.com/launch
  • Fabric8 Launcher installed on a Minishift or CDK

Procedure

  1. Use the Fabric8 Launcher tool to generate your own version of the example application.
  2. View the generated GitHub repository or download and extract the ZIP file that contains the example application source code.

3.1.2. REST API Level 0 design tradeoffs

Table 3.1. Design tradeoffs

ProsCons
  • The example application enables fast prototyping.
  • The API Design is flexible.
  • HTTP endpoints allow clients to be language-neutral.
  • As an application or service matures, the REST API Level 0 approach might not scale well. It might not support a clean API design or use cases with database interactions.

    • Any operations involving shared, mutable state must be integrated with an appropriate backing datastore.
    • All requests handled by this API design are scoped only to the container servicing the request. Subsequent requests might not be served by the same container.

3.1.3. Deploying the REST API Level 0 example application to OpenShift Online

Use one of the following options to execute the REST API Level 0 example application on OpenShift Online.

Although each method uses the same oc commands to deploy your application, using developers.redhat.com/launch provides an automated deployment workflow that executes the oc commands for you.

3.1.3.1. Deploying the example application using developers.redhat.com/launch

Prerequisites

Procedure

  1. Navigate to the developers.redhat.com/launch URL in a browser and log in.
  2. Follow on-screen instructions to create and launch your example application in Thorntail.

3.1.3.2. Authenticating the oc CLI client

To work with example applications on OpenShift Online using the oc command-line client, you must authenticate the client using the token provided by the OpenShift Online web interface.

Prerequisites

Procedure

  1. Navigate to the OpenShift Online URL in a browser.
  2. Click on the question mark icon in the top right-hand corner of the Web console, next to your user name.
  3. Select Command Line Tools in the drop-down menu.
  4. Find the text box that contains the oc login …​ command with the hidden token, and click the button next to it to copy its content to your clipboard.
  5. Paste the command into a terminal application. The command uses your authentication token to authenticate your oc CLI client with your OpenShift Online account.

    $ oc login OPENSHIFT_URL --token=MYTOKEN

3.1.3.3. Deploying the REST API Level 0 example application using the oc CLI client

Prerequisites

Procedure

  1. Clone your project from GitHub.

    $ git clone git@github.com:USERNAME/MY_PROJECT_NAME.git

    Alternatively, if you downloaded a ZIP file of your project, extract it.

    $ unzip MY_PROJECT_NAME.zip
  2. Create a new project in OpenShift.

    $ oc new-project MY_PROJECT_NAME
  3. Navigate to the root directory of your application.
  4. Use Maven to start the deployment to OpenShift.

    $ mvn clean fabric8:deploy -Popenshift

    This command uses the Fabric8 Maven Plugin to launch the S2I process on OpenShift and to start the pod.

  5. Check the status of your application and ensure your pod is running.

    $ oc get pods -w
    NAME                             READY     STATUS      RESTARTS   AGE
    MY_APP_NAME-1-aaaaa               1/1       Running     0          58s
    MY_APP_NAME-s2i-1-build           0/1       Completed   0          2m

    The MY_APP_NAME-1-aaaaa pod should have a status of Running once it is fully deployed and started. Your specific pod name will vary. The number in the middle will increase with each new build. The letters at the end are generated when the pod is created.

  6. After your example application is deployed and started, determine its route.

    Example Route Information

    $ oc get routes
    NAME                 HOST/PORT                                                     PATH      SERVICES        PORT      TERMINATION
    MY_APP_NAME         MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME      MY_APP_NAME      8080

    The route information of a pod gives you the base URL which you use to access it. In the example above, you would use http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME as the base URL to access the application.

3.1.4. Deploying the REST API Level 0 example application to Minishift or CDK

3.1.5. Deploying the REST API Level 0 example application to OpenShift Container Platform

The process of creating and deploying example applications to OpenShift Container Platform is similar to OpenShift Online:

Prerequisites

Procedure

3.1.6. Interacting with the unmodified REST API Level 0 example application for Thorntail

The example provides a default HTTP endpoint that accepts GET requests.

Prerequisites

  • Your application running
  • The curl binary or a web browser

Procedure

  1. Use curl to execute a GET request against the example. You can also use a browser to do this.

    $ curl http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/greeting
    {"content":"Hello, World!"}
  2. Use curl to execute a GET request with the name URL parameter against the example. You can also use a browser to do this.

    $ curl http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/greeting?name=Sarah
    {"content":"Hello, Sarah!"}
Note

From a browser, you can also use a form provided by the example to perform these same interactions. The form is located at the root of the project http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME.

3.1.7. Running the REST API Level 0 example application integration tests

This example application includes a self-contained set of integration tests. When run inside an OpenShift project, the tests:

  • Deploy a test instance of the application to the project.
  • Execute the individual tests on that instance.
  • Remove all instances of the application from the project when the testing is done.
Warning

Executing integration tests removes all existing instances of the example application from the target OpenShift project. To avoid accidentally removing your example application, ensure that you create and select a separate OpenShift project to execute the tests.

Prerequisites

  • The oc client authenticated
  • An empty OpenShift project

Procedure

Execute the following command to run the integration tests:

$ mvn clean verify -Popenshift,openshift-it

3.1.8. REST resources

3.2. Externalized Configuration example for Thorntail

Example proficiency level: Foundational.

Externalized Configuration provides a basic example of using a ConfigMap to externalize configuration. ConfigMap is an object used by OpenShift to inject configuration data as simple key and value pairs into one or more Linux containers while keeping the containers independent of OpenShift.

This example shows you how to:

  • Set up and configure a ConfigMap.
  • Use the configuration provided by the ConfigMap within an application.
  • Deploy changes to the ConfigMap configuration of running applications.

3.2.1. The externalized configuration design pattern

Whenever possible, externalize the application configuration and separate it from the application code. This allows the application configuration to change as it moves through different environments, but leaves the code unchanged. Externalizing the configuration also keeps sensitive or internal information out of your code base and version control. Many languages and application servers provide environment variables to support externalizing an application’s configuration.

Microservices architectures and multi-language (polyglot) environments add a layer of complexity to managing an application’s configuration. Applications consist of independent, distributed services, and each can have its own configuration. Keeping all configuration data synchronized and accessible creates a maintenance challenge.

ConfigMaps enable the application configuration to be externalized and used in individual Linux containers and pods on OpenShift. You can create a ConfigMap object in a variety of ways, including using a YAML file, and inject it into the Linux container. ConfigMaps also allow you to group and scale sets of configuration data. This lets you configure a large number of environments beyond the basic Development, Stage, and Production. You can find more information about ConfigMaps in the OpenShift documentation.

3.2.2. Externalized Configuration design tradeoffs

Table 3.2. Design Tradeoffs

ProsCons
  • Configuration is separate from deployments
  • Can be updated independently
  • Can be shared across services
  • Adding configuration to environment requires additional step
  • Has to be maintained separately
  • Requires coordination beyond the scope of a service

    {"content":"Hello World from a ConfigMap!"}
  2. Update the deployed ConfigMap configuration.

    $ oc edit configmap app-config

    Change the value for the greeting.message key to Bonjour %s from a ConfigMap! and save the file. After you save this, the changes will be propagated to your OpenShift instance.

  3. Rollout the new version of your application so the ConfigMap configuration changes are picked up.

    $ oc rollout latest dc/MY_APP_NAME
  4. Check the status of your example and ensure your new pod is running.

    $ oc get pods -w
    NAME                             READY     STATUS      RESTARTS   AGE
    MY_APP_NAME-1-aaaaa       1/1       Running     0          58s
    MY_APP_NAME-s2i-1-build   0/1       Completed   0          2m

    The MY_APP_NAME-1-aaaaa pod should have a status of Running once its fully deployed and started. Your specific pod name will vary. The number in the middle will increase with each new build. The letters at the end are generated when the pod is created.

  5. Execute a GET request using curl against the example with the updated ConfigMap configuration to see your updated greeting. You can also do this from your browser using the web form provided by the application.

    $ curl http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/greeting
    {"content":"Bonjour World from a ConfigMap!"}

3.3. Relational Database Backend example for Thorntail

Limitation: Run this example application on a Minishift or CDK. You can also use a manual workflow to deploy this example to OpenShift Online Pro and OpenShift Container Platform. This example is not currently available on OpenShift Online Starter.

Example proficiency level: Foundational.

What the Relational Database Backend example does

The Relational Database Backend example expands on the REST API Level 0 application to provide a basic example of performing create, read, update and delete (CRUD) operations on a PostgreSQL database using a simple HTTP API. CRUD operations are the four basic functions of persistent storage, widely used when developing an HTTP API dealing with a database.

The example also demonstrates the ability of the HTTP application to locate and connect to a database in OpenShift. Each runtime shows how to implement the connectivity solution best suited in the given case. The runtime can choose between options such as using JDBC, JPA, or accessing ORM APIs directly.

The example application exposes an HTTP API, which provides endpoints that allow you to manipulate data by performing CRUD operations over HTTP. The CRUD operations are mapped to HTTP Verbs. The API uses JSON formatting to receive requests and return responses to the user. The user can also use a user interface provided by the example to use the application. Specifically, this example provides an application that allows you to:

  • Navigate to the application web interface in your browser. This exposes a simple website allowing you to perform CRUD operations on the data in the my_data database.
  • Execute an HTTP GET request on the api/fruits endpoint.
  • Receive a response formatted as a JSON array containing the list of all fruits in the database.
  • Execute an HTTP GET request on the api/fruits/* endpoint while passing in a valid item ID as an argument.
  • Receive a response in JSON format containing the name of the fruit with the given ID. If no item matches the specified ID, the call results in an HTTP error 404.
  • Execute an HTTP POST request on the api/fruits endpoint passing in a valid name value to create a new entry in the database.
  • Execute an HTTP PUT request on the api/fruits/* endpoint passing in a valid ID and a name as an argument. This updates the name of the item with the given ID to match the name specified in your request.
  • Execute an HTTP DELETE request on the api/fruits/* endpoint, passing in a valid ID as an argument. This removes the item with the specified ID from the database and returns an HTTP code 204 (No Content) as a response. If you pass in an invalid ID, the call results in an HTTP error 404.

This example also contains a set of automated integration tests that can be used to verify that the application is fully integrated with the database.

This example does not showcase a fully matured RESTful model (level 3), but it does use compatible HTTP verbs and status, following the recommended HTTP API practices.

3.3.1. Relational Database Backend design tradeoffs

Table 3.3. Design Tradeoffs

ProsCons
  • Each runtime determines how to implement the database interactions. One can use a low-level connectivity API such as JDBC, some other can use JPA, and yet another can access ORM APIs directly. Each runtime decides what would be the best way.
  • Each runtime determines how the schema is created.
  • The PostgreSQL database provided with this example application is not backed up with persistent storage. Changes to the database are lost if you stop or redeploy the database pod. To use an external database with your example application’s pod in order to preserve changes, see the Integrating External Services chapter of the OpenShift Documentation. It is also possible to set up persistent storage with database containers on OpenShift. (For more details about using persistent storage with OpenShift and containers, see the Persistent Storage, Managing Volumes and Persistent Volumes chapters of the OpenShift Documentation).

  2. Create a new OpenShift project.

    $ oc new-project MY_PROJECT_NAME
  3. Navigate to the root directory of your application.
  4. Deploy the PostgreSQL database to OpenShift. Ensure that you use the following values for user name, password, and database name when creating your database application. The example application is pre-configured to use these values. Using different values prevents your application from integrating with the database.

    $ oc new-app -e POSTGRESQL_USER=luke -ePOSTGRESQL_PASSWORD=secret -ePOSTGRESQL_DATABASE=my_data openshift/postgresql-92-centos7 --name=my-database
  5. Check the status of your database and ensure the pod is running.

    $ oc get pods -w
    my-database-1-aaaaa   1/1       Running   0         45s
    my-database-1-deploy   0/1       Completed   0         53s

    The my-database-1-aaaaa pod should have a status of Running and should be indicated as ready once it is fully deployed and started. Your specific pod name will vary. The number in the middle will increase with each new build. The letters at the end are generated when the pod is created.

  6. Use maven to start the deployment to OpenShift.

    $ mvn clean fabric8:deploy -Popenshift

    This command uses the Fabric8 Maven Plugin to launch the S2I process on OpenShift and to start the pod.

  7. Check the status of your application and ensure your pod is running.

    $ oc get pods -w
    NAME                             READY     STATUS      RESTARTS   AGE
    MY_APP_NAME-1-aaaaa       1/1       Running     0          58s
    MY_APP_NAME-s2i-1-build   0/1       Completed   0          2m

    Your MY_APP_NAME-1-aaaaa pod should have a status of Running and should be indicated as ready once it is fully deployed and started.

  8. After your example application is deployed and started, determine its route.

    Example Route Information

    $ oc get routes
    NAME                 HOST/PORT                                     PATH      SERVICES             PORT      TERMINATION
    MY_APP_NAME   MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME      MY_APP_NAME   8080

    The route information of a pod gives you the base URL which you use to access it. In the example above, you would use http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME as the base URL to access the application.

Prerequisites

Procedure

3.3.6. Interacting with the Relational Database Backend API

When you have finished creating your example application, you can interact with it the following way:

Prerequisites

  • Your application running
  • The curl binary or a web browser

Procedure

  1. Obtain the URL of your application by executing the following command:

    $ oc get route MY_APP_NAME
    NAME                 HOST/PORT                                         PATH      SERVICES             PORT      TERMINATION

  2. To access the web interface of the database application, navigate to the application URL in your browser:

    http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME

    Alternatively, you can make requests directly on the api/fruits/* endpoint using curl:

    List all entries in the database:

    $ curl http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/fruits

    [ {
      "id" : 1,
      "name" : "Apple",
      "stock" : 10
    }, {
      "id" : 2,
      "name" : "Orange",
      "stock" : 10
    }, {
      "id" : 3,
      "name" : "Pear",
      "stock" : 10
    } ]

    Retrieve an entry with a specific ID

    $ curl http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/fruits/3

    {
      "id" : 3,
      "name" : "Pear",
      "stock" : 10
    }

    Create a new entry:

    $ curl -H "Content-Type: application/json" -X POST -d '{"name":"Peach","stock":1}'  http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/fruits

    {
      "id" : 4,
      "name" : "Peach",
      "stock" : 1
    }

    Update an Entry

    $ curl -H "Content-Type: application/json" -X PUT -d '{"name":"Apple","stock":"100"}'  http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/fruits/1

    {
      "id" : 1,
      "name" : "Apple",
      "stock" : 100
    }

    Delete an Entry:

    $ curl -X DELETE http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/fruits/1

Troubleshooting
  • If you receive an HTTP Error code 503 as a response after executing these commands, it means that the application is not ready yet.

3.3.7. Running the Relational Database Backend example application integration tests

This example application includes a self-contained set of integration tests. When run inside an OpenShift project, the tests:

  • Deploy a test instance of the application to the project.
  • Execute the individual tests on that instance.
  • Remove all instances of the application from the project when the testing is done.
Warning

Executing integration tests removes all existing instances of the example application from the target OpenShift project. To avoid accidentally removing your example application, ensure that you create and select a separate OpenShift project to execute the tests.

Prerequisites

  • The oc client authenticated
  • An empty OpenShift project

Procedure

Execute the following command to run the integration tests:

$ mvn clean verify -Popenshift,openshift-it

3.4. Health Check example for Thorntail

Example proficiency level: Foundational.

When you deploy an application, it is important to know if it is available and if it can start handling incoming requests. Implementing the health check pattern allows you to monitor the health of an application, which includes if an application is available and whether it is able to service requests.

Note

If you are not familiar with the health check terminology, see the Section 3.4.1, “Health check concepts” section first.

The purpose of this use case is to demonstrate the health check pattern through the use of probing. Probing is used to report the liveness and readiness of an application. In this use case, you configure an application which exposes an HTTP health endpoint to issue HTTP requests. If the container is alive, according to the liveness probe on the health HTTP endpoint, the management platform receives 200 as return code and no further action is required. If the health HTTP endpoint does not return a response, for example if the thread is blocked, then the application is not considered alive according to the liveness probe. In that case, the platform kills the pod corresponding to that application and recreates a new pod to restart the application.

This use case also allows you to demonstrate and use a readiness probe. In cases where the application is running but is unable to handle requests, such as when the application returns an HTTP 503 response code during restart, this application is not considered ready according to the readiness probe. If the application is not considered ready by the readiness probe, requests are not routed to that application until it is considered ready according to the readiness probe.

3.4.1. Health check concepts

In order to understand the health check pattern, you need to first understand the following concepts:

Liveness
Liveness defines whether an application is running or not. Sometimes a running application moves into an unresponsive or stopped state and needs to be restarted. Checking for liveness helps determine whether or not an application needs to be restarted.
Readiness
Readiness defines whether a running application can service requests. Sometimes a running application moves into an error or broken state where it can no longer service requests. Checking readiness helps determine whether or not requests should continue to be routed to that application.
Fail-over
Fail-over enables failures in servicing requests to be handled gracefully. If an application fails to service a request, that request and future requests can then fail-over or be routed to another application, which is usually a redundant copy of that same application.
Resilience and Stability
Resilience and Stability enable failures in servicing requests to be handled gracefully. If an application fails to service a request due to connection loss, in a resilient system that request can be retried after the connection is re-established.
Probe
A probe is a Kubernetes action that periodically performs diagnostics on a running container.

    MY_APP_NAME-s2i-1-build           0/1       Completed   0          2m

    The MY_APP_NAME-1-aaaaa pod should have a status of Running once its fully deployed and started. You should also wait for your pod to be ready before proceeding, which is shown in the READY column. For example, MY_APP_NAME-1-aaaaa is ready when the READY column is 1/1. Your specific pod name will vary. The number in the middle will increase with each new build. The letters at the end are generated when the pod is created.

  6. After your example application is deployed and started, determine its route.

    Example Route Information

    $ oc get routes
    NAME                 HOST/PORT                                                     PATH      SERVICES        PORT      TERMINATION
    MY_APP_NAME         MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME      MY_APP_NAME      8080

    The route information of a pod gives you the base URL which you use to access it. In the example above, you would use http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME as the base URL to access the application.

3.4.5. Deploying the Health Check example application to OpenShift Container Platform

The process of creating and deploying example applications to OpenShift Container Platform is similar to OpenShift Online:

Prerequisites

Procedure

3.4.6. Interacting with the unmodified Health Check example application

After you deploy the example application, you will have the MY_APP_NAME service running. The MY_APP_NAME service exposes the following REST endpoints:

/api/greeting
Returns a name as a String.
/api/stop
Forces the service to become unresponsive as means to simulate a failure.

The following steps demonstrate how to verify the service availability and simulate a failure. This failure of an available service causes the OpenShift self-healing capabilities to be trigger on the service.

Alternatively, you can use the web interface to perform these steps.

  1. Use curl to execute a GET request against the MY_APP_NAME service. You can also use a browser to do this.

    $ curl http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/greeting
    {"content":"Hello, World!"}
  2. Invoke the /api/stop endpoint and verify the availability of the /api/greeting endpoint shortly after that.

    Invoking the /api/stop endpoint simulates an internal service failure and triggers the OpenShift self-healing capabilities. When invoking /api/greeting after simulating the failure, the service should return a HTTP status 503.

    $ curl http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/stop

    (followed by)

    $ curl http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/api/greeting
    <html>
      <head><title>Error</title></head>
      <body>503 - Service Unavailable</body>
    </html>
  3. Use oc get pods -w to continuously watch the self-healing capabilities in action.

    While invoking the service failure, you can watch the self-healing capabilities in action on OpenShift console, or with the oc client tools. You should see the number of pods in the READY state move to zero (0/1) and after a short period (less than one minute) move back up to one (1/1). In addition to that, the RESTARTS count increases every time you you invoke the service failure.

    $ oc get pods -w
    NAME                           READY     STATUS    RESTARTS   AGE
    MY_APP_NAME-1-26iy7   0/1       Running   5          18m
    MY_APP_NAME-1-26iy7   1/1       Running   5         19m
  4. Optional: Use the web interface to invoke the service.

    Alternatively to the interaction using the terminal window, you can use the web interface provided by the service to invoke the different methods and watch the service move through the life cycle phases.

    http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME
  5. Optional: Use the web console to view the log output generated by the application at each stage of the self-healing process.

    1. Navigate to your project.
    2. On the sidebar, click on Monitoring.
    3. In the upper right-hand corner of the screen, click on Events to display the log messages.
    4. Optional: Click View Details to display a detailed view of the Event log.

    The health check application generates the following messages:

    MessageStatus

    Unhealthy

    Readiness probe failed. This message is expected and indicates that the simulated failure of the /api/greeting endpoint has been detected and the self-healing process starts.

    Killing

    The unavailable Docker container running the service is being killed before being re-created.

    Pulling

    Downloading the latest version of docker image to re-create the container.

    Pulled

    Docker image downloaded successfully.

    Created

    Docker container has been successfully created

    Started

    Docker container is ready to handle requests

3.4.7. Running the Health Check example application integration tests

This example application includes a self-contained set of integration tests. When run inside an OpenShift project, the tests:

  • Deploy a test instance of the application to the project.
  • Execute the individual tests on that instance.
  • Remove all instances of the application from the project when the testing is done.
Warning

Executing integration tests removes all existing instances of the example application from the target OpenShift project. To avoid accidentally removing your example application, ensure that you create and select a separate OpenShift project to execute the tests.

Prerequisites

  • The oc client authenticated
  • An empty OpenShift project

Procedure

Execute the following command to run the integration tests:

$ mvn clean verify -Popenshift,openshift-it

3.5. Circuit Breaker example for Thorntail

Limitation: Run this example application on a Minishift or CDK. You can also use a manual workflow to deploy this example to OpenShift Online Pro and OpenShift Container Platform. This example is not currently available on OpenShift Online Starter.

Example proficiency level: Foundational.

The Circuit Breaker example demonstrates a generic pattern for reporting the failure of a service and then limiting access to the failed service until it becomes available to handle requests. This helps prevent cascading failure in other services that depend on the failed services for functionality.

This example shows you how to implement a Circuit Breaker and Fallback pattern in your services.

3.5.1. The circuit breaker design pattern

The Circuit Breaker is a pattern intended to:

  • Reduce the impact of network failure and high latency on service architectures where services synchronously invoke other services.

    If one of the services:

    • becomes unavailable due to network failure, or
    • incurs unusually high latency values due to overwhelming traffic,

    other services attempting to call its endpoint may end up exhausting critical resources in an attempt to reach it, rendering themselves unusable.

  • Prevent the condition also known as cascading failure, which can render the entire microservice architecture unusable.
  • Act as a proxy between a protected function and a remote function, which monitors for failures.
  • Trip once the failures reach a certain threshold, and all further calls to the circuit breaker return an error or a predefined fallback response, without the protected call being made at all.

The Circuit Breaker usually also contain an error reporting mechanism that notifies you when the Circuit Breaker trips.

Circuit breaker implementation
  • With the Circuit Breaker pattern implemented, a service client invokes a remote service endpoint via a proxy at regular intervals.
  • If the calls to the remote service endpoint fail repeatedly and consistently, the Circuit Breaker trips, making all calls to the service fail immediately over a set timeout period and returns a predefined fallback response.
  • When the timeout period expires, a limited number of test calls are allowed to pass through to the remote service to determine whether it has healed, or remains unavailable.

    • If the test calls fail, the Circuit Breaker keeps the service unavailable and keeps returning the fallback responses to incoming calls.
    • If the test calls succeed, the Circuit Breaker closes, fully enabling traffic to reach the remote service again.

3.5.2. Circuit Breaker design tradeoffs

Table 3.4. Design Tradeoffs

ProsCons
  • Enables a service to handle the failure of other services it invokes.
  • Optimizing the timeout values can be challenging

    • Larger-than-necessary timeout values may generate excessive latency.
    • Smaller-than-necessary timeout values may introduce false positives.

3.5.3. Viewing the example application source code and README

Prerequisites

One of the following:

  • Access to developers.redhat.com/launch
  • Fabric8 Launcher installed on a Minishift or CDK

Procedure

  2. Click on the question mark icon in the top right-hand corner of the Web console, next to your user name.
  3. Select Command Line Tools in the drop-down menu.
  4. Find the text box that contains the oc login …​ command with the hidden token, and click the button next to it to copy its content to your clipboard.
  5. Paste the command into a terminal application. The command uses your authentication token to authenticate your oc CLI client with your OpenShift Online account.

    $ oc login OPENSHIFT_URL --token=MYTOKEN

3.5.4.3. Deploying the Circuit Breaker example application using the oc CLI client

Prerequisites

Procedure

  1. Clone your project from GitHub.

    $ git clone git@github.com:USERNAME/MY_PROJECT_NAME.git

    Alternatively, if you downloaded a ZIP file of your project, extract it.

    $ unzip MY_PROJECT_NAME.zip
  2. Create a new OpenShift project.

    $ oc new-project MY_PROJECT_NAME
  3. Navigate to the root directory of your application.
  4. Use Maven to start the deployment to OpenShift.

    $ mvn clean fabric8:deploy -Popenshift

    This command uses the Fabric8 Maven Plugin to launch the S2I process on OpenShift and to start the pod.

  5. Check the status of your application and ensure your pod is running.

    $ oc get pods -w
    NAME                             READY     STATUS      RESTARTS   AGE
    MY_APP_NAME-greeting-1-aaaaa     1/1       Running   0           17s
    MY_APP_NAME-greeting-1-deploy    0/1       Completed 0           22s
    MY_APP_NAME-name-1-aaaaa         1/1       Running   0           14s
    MY_APP_NAME-name-1-deploy        0/1       Completed 0           28s

    Both the MY_APP_NAME-greeting-1-aaaaa and MY_APP_NAME-name-1-aaaaa pods should have a status of Running once they are fully deployed and started. You should also wait for your pods to be ready before proceeding, which is shown in the READY column. For example, MY_APP_NAME-greeting-1-aaaaa is ready when the READY column is 1/1. Your specific pod names will vary. The number in the middle will increase with each new build. The letters at the end are generated when the pod is created.

  6. After your example application is deployed and started, determine its route.

    Example Route Information

    $ oc get routes
    NAME                 HOST/PORT                                                     PATH      SERVICES        PORT      TERMINATION
    MY_APP_NAME-greeting   MY_APP_NAME-greeting-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME            MY_APP_NAME-greeting   8080                    None

3.5.5.4. Deploying the Circuit Breaker example application using the oc CLI client

Prerequisites

Procedure

  1. Clone your project from GitHub.

    $ git clone git@github.com:USERNAME/MY_PROJECT_NAME.git

    Alternatively, if you downloaded a ZIP file of your project, extract it.

    $ unzip MY_PROJECT_NAME.zip
  2. Create a new OpenShift project.

    $ oc new-project MY_PROJECT_NAME
  3. Navigate to the root directory of your application.
  4. Use Maven to start the deployment to OpenShift.

    $ mvn clean fabric8:deploy -Popenshift

    This command uses the Fabric8 Maven Plugin to launch the S2I process on OpenShift and to start the pod.

  5. Check the status of your application and ensure your pod is running.

    $ oc get pods -w
    NAME                             READY     STATUS      RESTARTS   AGE
    MY_APP_NAME-greeting-1-aaaaa     1/1       Running   0           17s

    The route information of a pod gives you the base URL which you use to access it. In the example above, you would use http://MY_APP_NAME-greeting-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME as the base URL to access the application.

3.5.6. Deploying the Circuit Breaker example application to OpenShift Container Platform

The process of creating and deploying example applications to OpenShift Container Platform is similar to OpenShift Online:

Prerequisites

Procedure

3.5.7. Interacting with the unmodified Thorntail Circuit Breaker example application

After you have the Thorntail example application deployed, you have the following services running:

MY_APP_NAME-name

Exposes the following endpoints:

  • the /api/name endpoint, which returns a name when this service is working, and an error when this service is set up to demonstrate failure.
  • the /api/state endpoint, which controls the behavior of the /api/name endpoint and determines whether the service works correctly or demonstrates failure.
MY_APP_NAME-greeting

Exposes the following endpoints:

  • the /api/greeting endpoint that you can call to get a personalized greeting response.

    When you call the /api/greeting endpoint, it issues a call against the /api/name endpoint of the MY_APP_NAME-name service as part of processing your request. The call made against the /api/name endpoint is protected by the Circuit Breaker.

    If the remote endpoint is available, the name service responds with an HTTP code 200 (OK) and you receive the following greeting from the /api/greeting endpoint:

    {"content":"Hello, World!"}

    If the remote endpoint is unavailable, the name service responds with an HTTP code 500 (Internal server error) and you receive a predefined fallback response from the /api/greeting endpoint:

    {"content":"Hello, Fallback!"}
  • the /api/cb-state endpoint, which returns the state of the Circuit Breaker. The state can be:

    • open : the circuit breaker is preventing requests from reaching the failed service,
    • closed: the circuit breaker is allowing requests to reach the service.

The following steps demonstrate how to verify the availability of the service, simulate a failure and receive a fallback response.

  1. Use curl to execute a GET request against the MY_APP_NAME-greeting service. You can also use the Invoke button in the web interface to do this.

    $ curl http://MY_APP_NAME-greeting-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME/api/greeting
    {"content":"Hello, World!"}
  2. To simulate the failure of the MY_APP_NAME-name service you can:

    • use the Toggle button in the web interface.
    • scale the number of replicas of the pod running the MY_APP_NAME-name service down to 0.
    • execute an HTTP PUT request against the /api/state endpoint of the MY_APP_NAME-name service to set its state to fail.

      $ curl -X PUT -H "Content-Type: application/json" -d '{"state": "fail"}' http://MY_APP_NAME-name-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME/api/state
  3. Invoke the /api/greeting endpoint. When several requests on the /api/name endpoint fail:

    1. the Circuit Breaker opens,
    2. the state indicator in the web interface changes from CLOSED to OPEN,
    3. the Circuit Breaker issues a fallback response when you invoke the /api/greeting endpoint:

      $ curl http://MY_APP_NAME-greeting-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME/api/greeting
      {"content":"Hello, Fallback!"}
  4. Restore the name MY_APP_NAME-name service to availability. To do this you can:

    • use the Toggle button in the web interface.
    • scale the number of replicas of the pod running the MY_APP_NAME-name service back up to 1.
    • execute an HTTP PUT request against the /api/state endpoint of the MY_APP_NAME-name service to set its state back to ok.

      $ curl -X PUT -H "Content-Type: application/json" -d '{"state": "ok"}' http://MY_APP_NAME-name-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME/api/state
  5. Invoke the /api/greeting endpoint again. When several requests on the /api/name endpoint succeed:

    1. the Circuit Breaker closes,
    2. the state indicator in the web interface changes from OPEN to CLOSED,
    3. the Circuit Breaker issues a returns the Hello World! greeting when you invoke the /api/greeting endpoint:

      $ curl http://MY_APP_NAME-greeting-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME/api/greeting
      {"content":"Hello, World!"}

3.5.8. Running the Circuit Breaker example application integration tests

This example application includes a self-contained set of integration tests. When run inside an OpenShift project, the tests:

  • Deploy a test instance of the application to the project.
  • Execute the individual tests on that instance.
  • Remove all instances of the application from the project when the testing is done.
Warning

Executing integration tests removes all existing instances of the example application from the target OpenShift project. To avoid accidentally removing your example application, ensure that you create and select a separate OpenShift project to execute the tests.

Prerequisites

  • The oc client authenticated
  • An empty OpenShift project

Procedure

Execute the following command to run the integration tests:

$ mvn clean verify -Popenshift,openshift-it

3.5.9. Using Hystrix Dashboard to monitor the circuit breaker

Hystrix Dashboard lets you easily monitor the health of your services in real time by aggregating Hystrix metrics data from an event stream and displaying them on one screen.

Prerequisites

  • The application deployed

Procedure

  1. Log in to your Minishift or CDK cluster.

    $ oc login OPENSHIFT_URL --token=MYTOKEN
  2. To access the Web console, use your browser to navigate to your Minishift or CDK URL.
  3. Navigate to the project that contains your Circuit Breaker application.

    $ oc project MY_PROJECT_NAME
  4. Import the YAML template for the Hystrix Dashboard application. You can do this by clicking Add to Project, then selecting the Import YAML / JSON tab, and copying the contents of the YAML file into the text box. Alternatively, you can execute the following command:

    $ oc create -f https://raw.githubusercontent.com/snowdrop/openshift-templates/master/hystrix-dashboard/hystrix-dashboard.yml
  5. Click the Create button to create the Hystrix Dashboard application based on the template. Alternatively, you can execute the following command.

    $ oc new-app --template=hystrix-dashboard
  6. Wait for the pod containing Hystrix Dashboard to deploy.
  7. Obtain the route of your Hystrix Dashboard application.

    $ oc get route hystrix-dashboard
    NAME                HOST/PORT                                                    PATH      SERVICES            PORT      TERMINATION   WILDCARD
    hystrix-dashboard   hystrix-dashboard-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME                 hystrix-dashboard   <all>                   None
  8. To access the Dashboard, open the Dashboard application route URL in your browser. Alternatively, you can navigate to the Overview screen in the Web console and click the route URL in the header above the pod containing your Hystrix Dashboard application.
  9. To use the Dashboard to monitor the MY_APP_NAME-greeting service, replace the default event stream address with the following address and click the Monitor Stream button.

    http://MY_APP_NAME-greeting/hystrix.stream

3.6. Secured example application for Thorntail

Limitation: Run this example application on a Minishift or CDK. You can also use a manual workflow to deploy this example to OpenShift Online Pro and OpenShift Container Platform. This example is not currently available on OpenShift Online Starter.

Example proficiency level: Advanced.

The Secured example application secures a REST endpoint using Red Hat SSO. (This example expands on the REST API Level 0 example).

Red Hat SSO:

  • Implements the Open ID Connect protocol which is an extension of the OAuth 2.0 specification.
  • Issues access tokens to provide clients with various access rights to secured resources.

Securing an application with SSO enables you to add security to your applications while centralizing the security configuration.

Important

This example comes with Red Hat SSO pre-configured for demonstration purposes, it does not explain its principles, usage, or configuration. Before using this example, ensure that you are familiar with the basic concepts related to Red Hat SSO.

3.6.1. The Secured project structure

The SSO example contains:

  • the sources for the Greeting service, which is the one which we are going to to secure
  • a template file (service.sso.yaml) to deploy the SSO server
  • the Keycloak adapter configuration to secure the service

3.6.2. Viewing the example application source code and README

Prerequisites

One of the following:

  • Access to developers.redhat.com/launch
  • Fabric8 Launcher installed on a Minishift or CDK

Procedure

  1. Use the Fabric8 Launcher tool to generate your own version of the example application.
  2. View the generated GitHub repository or download and extract the ZIP file that contains the example application source code.

3.6.3. Red Hat SSO deployment configuration

The service.sso.yaml file in this example contains all OpenShift configuration items to deploy a pre-configured Red Hat SSO server. The SSO server configuration has been simplified for the sake of this exercise and does provide an out-of-the-box configuration, with pre-configured users and security settings. The service.sso.yaml file also contains very long lines, and some text editors, such as gedit, may have issues reading this file.

Warning

It is not recommended to use this SSO configuration in production. Specifically, the simplifications made to the example security configuration impact the ability to use it in a production environment.

The default configuration includes both public and private keys in the yaml configuration files.

We did this because the end user can deploy Red Hat SSO module and have it in a usable state without needing to know the internals or how to configure Red Hat SSO.

In production, do not store private keys under source control. They should be added by the server administrator.

The configured clients accept any callback url.

To avoid having a custom configuration for each runtime, we avoid the callback verification that is required by the OAuth2 specification.

An application-specific callback URL should be provided with a valid domain name.

Clients do not require SSL/TLS and the secured applications are not exposed over HTTPS.

The examples are simplified by not requiring certificates generated for each runtime.

In production a secure application should use HTTPS rather than plain HTTP.

The token timeout has been increased to 10 minutes from the default of 1 minute.

Provides a better user experience when working with the command line examples

From a security perspective, the window an attacker would have to guess the access token is extended. It is recommended to keep this window short as it makes it much harder for a potential attacker to guess the current token.

3.6.4. Red Hat SSO realm model

The master realm is used to secure this example. There are two pre-configured application client definitions that provide a model for command line clients and the secured REST endpoint.

There are also two pre-configured users in the Red Hat SSO master realm that can be used to validate various authentication and authorization outcomes: admin and alice.

3.6.4.1. Red Hat SSO users

The realm model for the secured examples includes two users:

admin
The admin user has a password of admin and is the realm administrator. This user has full access to the Red Hat SSO administration console, but none of the role mappings that are required to access the secured endpoints. You can use this user to illustrate the behavior of an authenticated, but unauthorized user.
alice

The alice user has a password of password and is the canonical application user. This user will demonstrate successful authenticated and authorized access to the secured endpoints. An example representation of the role mappings is provided in this decoded JWT bearer token:

{
  "jti": "0073cfaa-7ed6-4326-ac07-c108d34b4f82",
  "exp": 1510162193,

  "preferred_username": "alice", 5
  "given_name": "Alice",
  "family_name": "InChains",
  "email": "alice@keycloak.org"
}
1
The iss field corresponds to the Red Hat SSO realm instance URL that issues the token. This must be configured in the secured endpoint deployments in order for the token to be verified.
2
The roles object provides the roles that have been granted to the user at the global realm level. In this case alice has been granted the example-admin role. We will see that the secured endpoint will look to the realm level for authorized roles.
3
The resource_access object contains resource specific role grants. Under this object you will find an object for each of the secured endpoints.
4
The resource_access.secured-example-endpoint.roles object contains the roles granted to alice for the secured-example-endpoint resource.
5
The preferred_username field provides the username that was used to generate the access token.

3.6.4.2. The application clients

The OAuth 2.0 specification allows you to define a role for application clients that access secured resources on behalf of resource owners. The master realm has the following application clients defined:

demoapp
This is a confidential type client with a client secret that is used to obtain an access token. The token contains grants for the alice user which enable alice to access the Thorntail, Eclipse Vert.x, Node.js and Spring Boot based REST example application deployments.
secured-example-endpoint
The secured-example-endpoint is a bearer-only type of client that requires a example-admin role for accessing the associated resources, specifically the Greeting service.

3.6.5. Thorntail SSO adapter configuration

The SSO adapter is the client side, or client to the SSO server, component that enforces security on the web resources. In this specific case, it is the greeting service.

In Thorntail, the security configuration breaks down into two notable assets:

  • The web.xml configuration to enact the security for the service
  • The keycloak.json configuration for the keycloak adapter.

Enacting Security using web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="2.5">
  <security-constraint>
    <web-resource-collection>
      <url-pattern>/api/greeting</url-pattern> 1
    </web-resource-collection>
    <auth-constraint>
      <role-name>example-admin</role-name> 2
    </auth-constraint>
  </security-constraint>

  <login-config>
    <auth-method>KEYCLOAK</auth-method> 3
  </login-config>

  <security-role>
    <role-name>example-admin</role-name>
  </security-role>
</web-app>

1
The web context that is to be secured.
2
The role needed to access the endpoint.
3
Using keycloak as the security provider.

Enacting Security in Keycloak Adapter using keycloak.json

{
  "realm": "master", 1
  "resource": "secured-example-endpoint", 2
  "realm-public-key": "...", 3
  "auth-server-url": "${sso.auth.server.url}", 4
  "ssl-required": "external",
  "disable-trust-manager": true,
  "bearer-only": true, 5
  "use-resource-role-mappings": true
}

1
The security realm to be used.
2
The actual keycloak client configuration.
3
PEM format of the realm public key. You can obtain this from the administration console.
4
The address of the Red Hat SSO server (Interpolation at build time).
5
If enabled the adapter will not attempt to authenticate users, but only verify bearer tokens.

The web.xml enables keycloak and enforces protection of the Greeting service web resource endpoint. The keycloak.json configures the security adapter to interact with Red Hat SSO.

3.6.6. Deploying the Secured example application to Minishift or CDK

3.6.6.1. Getting the Fabric8 Launcher tool URL and credentials

You need the Fabric8 Launcher tool URL and user credentials to create and deploy example applications on Minishift or CDK. This information is provided when the Minishift or CDK is started.

Prerequisites

Procedure

  1. Navigate to the console where you started Minishift or CDK.
  2. Check the console output for the URL and user credentials you can use to access the running Fabric8 Launcher:

    Example Console Output from a Minishift or CDK Startup

    $ oc login OPENSHIFT_URL --token=MYTOKEN

3.6.6.4. Deploying the Secured example application using the oc CLI client

Prerequisites

Procedure

  1. Clone your project from GitHub.

    $ git clone git@github.com:USERNAME/MY_PROJECT_NAME.git

    Alternatively, if you downloaded a ZIP file of your project, extract it.

    $ unzip MY_PROJECT_NAME.zip
  2. Create a new OpenShift project.

    $ oc new-project MY_PROJECT_NAME
  3. Navigate to the root directory of your application.
  4. Deploy the Red Hat SSO server using the service.sso.yaml file from your example ZIP file:

    $ oc create -f service.sso.yaml
  5. Use Maven to start the deployment to Minishift or CDK.

    $ mvn clean fabric8:deploy -Popenshift -DskipTests \
          -DSSO_AUTH_SERVER_URL=$(oc get route secure-sso -o jsonpath='{"https://"}{.spec.host}{"/auth\n"}')

    This command uses the Fabric8 Maven Plugin to launch the S2I process on Minishift or CDK and to start the pod.

This process generates the uberjar file as well as the OpenShift resources and deploys them to the current project on your Minishift or CDK server.

3.6.7. Deploying the Secured example application to OpenShift Container Platform

In addition to the Minishift or CDK, you can create and deploy the example on OpenShift Container Platform with only minor differences. The most important difference is that you need to create the example application on Minishift or CDK before you can deploy it with OpenShift Container Platform.

Prerequisites

3.6.7.1. Authenticating the oc CLI client

To work with example applications on OpenShift Container Platform using the oc command-line client, you must authenticate the client using the token provided by the OpenShift Container Platform web interface.

Prerequisites

  • An account at OpenShift Container Platform.

Procedure

  1. Navigate to the OpenShift Container Platform URL in a browser.
  2. Click on the question mark icon in the top right-hand corner of the Web console, next to your user name.
  3. Select Command Line Tools in the drop-down menu.
  4. Find the text box that contains the oc login …​ command with the hidden token, and click the button next to it to copy its content to your clipboard.
  5. Paste the command into a terminal application. The command uses your authentication token to authenticate your oc CLI client with your OpenShift Container Platform account.

    $ oc login OPENSHIFT_URL --token=MYTOKEN

3.6.7.2. Deploying the Secured example application using the oc CLI client

Prerequisites

Procedure

  1. Clone your project from GitHub.

    $ git clone git@github.com:USERNAME/MY_PROJECT_NAME.git

    Alternatively, if you downloaded a ZIP file of your project, extract it.

    $ unzip MY_PROJECT_NAME.zip
  2. Create a new OpenShift project.

    $ oc new-project MY_PROJECT_NAME
  3. Navigate to the root directory of your application.
  4. Deploy the Red Hat SSO server using the service.sso.yaml file from your example ZIP file:

    $ oc create -f service.sso.yaml
  5. Use Maven to start the deployment to OpenShift Container Platform.

    $ mvn clean fabric8:deploy -Popenshift -DskipTests \
          -DSSO_AUTH_SERVER_URL=$(oc get route secure-sso -o jsonpath='{"https://"}{.spec.host}{"/auth\n"}')

    This command uses the Fabric8 Maven Plugin to launch the S2I process on OpenShift Container Platform and to start the pod.

This process generates the uberjar file as well as the OpenShift resources and deploys them to the current project on your OpenShift Container Platform server.

3.6.8. Authenticating to the Secured example application API endpoint

The Secured example application provides a default HTTP endpoint that accepts GET requests if the caller is authenticated and authorized. The client first authenticates against the Red Hat SSO server and then performs a GET request against the Secured example application using the access token returned by the authentication step.

3.6.8.1. Getting the Secured example application API endpoint

When using a client to interact with the example, you must specify the Secured example application endpoint, which is the PROJECT_ID service.

Prerequisites

  • The Secured example application deployed and running.
  • The oc client authenticated.

Procedure

  1. In a terminal application, execute the oc get routes command.

    A sample output is shown in the following table:

    Example 3.1. List of Secured endpoints

    NameHost/PortPathServicesPortTermination

    secure-sso

    secure-sso-myproject.LOCAL_OPENSHIFT_HOSTNAME

     

    secure-sso

    <all>

    passthrough

    PROJECT_ID

    PROJECT_ID-myproject.LOCAL_OPENSHIFT_HOSTNAME

     

    PROJECT_ID

    <all>

     

    sso

    sso-myproject.LOCAL_OPENSHIFT_HOSTNAME

     

    sso

    <all>

     

    In the above example, the example endpoint would be http://PROJECT_ID-myproject.LOCAL_OPENSHIFT_HOSTNAME. PROJECT_ID is based on the name you entered when generating your example using developers.redhat.com/launch or the Fabric8 Launcher tool.

3.6.8.2. Authenticating HTTP requests using the command line

Request a token by sending a HTTP POST request to the Red Hat SSO server. In the following example, the jq CLI tool is used to extract the token value from the JSON response.

Prerequisites

Procedure

  1. Request an access token with curl, the credentials, and <SSO_AUTH_SERVER_URL> and extract the token from the response with the jq command:

    curl -sk -X POST https://<SSO_AUTH_SERVER_URL>/auth/realms/master/protocol/openid-connect/token \
      -d grant_type=password \
      -d username=alice\
      -d password=password \
      -d client_id=demoapp \
      -d client_secret=1daa57a2-b60e-468b-a3ac-25bd2dc2eadc \
      | jq -r '.access_token'

    <SSO_AUTH_SERVER_URL> is the url of the secure-sso service.

    The attributes, such as username, password, and client_secret are usually kept secret, but the above command uses the default provided credentials with this example for demonstration purpose.

    If you do not want to use jq to extract the token, you can run just the curl command and manually extract the access token.

    Note

    The -sk option tells curl to ignore failures resulting from self-signed certificates. Do not use this option in a production environment. On macOS, you must have curl version 7.56.1 or greater installed. It must also be built with OpenSSL.

  1. Invoke the Secured service. Attach the access (bearer) token to the HTTP headers:

    $ curl -v -H "Authorization: Bearer <TOKEN>" http://<SERVICE_HOST>/api/greeting
    
    {
        "content": "Hello, World!",
        "id": 2
    }

    Example 3.2. A sample GET Request Headers with an Access (Bearer) Token

    > GET /api/greeting HTTP/1.1
    > Host: <SERVICE_HOST>
    > User-Agent: curl/7.51.0
    > Accept: */*
    > Authorization: Bearer <TOKEN>

    <SERVICE_HOST> is the URL of the secured example endpoint. For more information, see Section 3.6.8.1, “Getting the Secured example application API endpoint”.

  2. Verify the signature of the access token.

    The access token is a JSON Web Token, so you can decode it using the JWT Debugger:

    1. In a web browser, navigate to the JWT Debugger website.
    2. Select RS256 from the Algorithm drop down menu.

      Note

      Make sure the web form has been updated after you made the selection, so it displays the correct RSASHA256(…​) information in the Signature section. If it has not, try switching to HS256 and then back to RS256.

    3. Paste the following content in the topmost text box into the VERIFY SIGNATURE section:

      -----BEGIN PUBLIC KEY-----
      MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAoETnPmN55xBJjRzN/cs30OzJ9olkteLVNRjzdTxFOyRtS2ovDfzdhhO9XzUcTMbIsCOAZtSt8K+6yvBXypOSYvI75EUdypmkcK1KoptqY5KEBQ1KwhWuP7IWQ0fshUwD6jI1QWDfGxfM/h34FvEn/0tJ71xN2P8TI2YanwuDZgosdobx/PAvlGREBGuk4BgmexTOkAdnFxIUQcCkiEZ2C41uCrxiS4CEe5OX91aK9HKZV4ZJX6vnqMHmdDnsMdO+UFtxOBYZio+a1jP4W3d7J5fGeiOaXjQCOpivKnP2yU2DPdWmDMyVb67l8DRA+jh0OJFKZ5H2fNgE3II59vdsRwIDAQAB
      -----END PUBLIC KEY-----
      Note

      This is the master realm public key from the Red Hat SSO server deployment of the Secured example application.

    4. Paste the token output from the client output into the Encoded box.

      The Signature Verified sign is displayed on the debugger page.

3.6.8.3. Authenticating HTTP requests using the web interface

In addition to the HTTP API, the secured endpoint also contains a web interface to interact with.

The following procedure is an exercise for you to see how security is enforced, how you authenticate, and how you work with the authentication token.

Prerequisites

Procedure

  1. In a web browser, navigate to the endpoint URL.
  2. Perform an unauthenticated request:

    1. Click the Invoke button.

      Figure 3.1. Unauthenticated Secured Example Web Interface

      sso main

      The services responds with an HTTP 401 Unauthorized status code.

      Figure 3.2. Unauthenticated Error Message

      sso unauthenticated
  3. Perform an authenticated request as a user:

    1. Click the Login button to authenticate against Red Hat SSO. You will be redirected to the SSO server.
    2. Log in as the Alice user. You will be redirected back to the web interface.

      Note

      You can see the access (bearer) token in the command line output at the bottom of the page.

      Figure 3.3. Authenticated Secured Example Web Interface (as Alice)

      sso alice
    3. Click Invoke again to access the Greeting service.

      Confirm that there is no exception and the JSON response payload is displayed. This means the service accepted your access (bearer) token and you are authorized access to the Greeting service.

      Figure 3.4. The Result of an Authenticated Greeting Request (as Alice)

      sso invoke alice
    4. Log out.
  4. Perform an authenticated request as an admininstrator:

    1. Click the Invoke button.

      Confirm that this sends an unauthenticated request to the Greeting service.

    2. Click the Login button and log in as the admin user.

      Figure 3.5. Authenticated Secured Example Web Interface (as admin)

      sso admin
  5. Click the Invoke button.

    The service responds with an HTTP 403 Forbidden status code because the admin user is not authorized to access the Greeting service.

    Figure 3.6. Unauthorized Error Message

    sso unauthorized

3.6.9. Running the Thorntail Secured example application integration tests

Important

The keycloak-authz-client library for Thorntail is provided as a Technology Preview.

Prerequisites

  • The oc client authenticated.
Procedure

Executing integration tests removes all existing instances of the example application from the target OpenShift project. To avoid accidentally removing your example application, ensure that you create and select a separate OpenShift project to execute the tests.

  1. In a terminal application, navigate to the directory with your project.
  2. Deploy the Red Hat SSO server:

    oc apply -f service.sso.yaml
  3. Wait until the Red Hat SSO server is ready. Go to the Web console or view the output of oc get pods to check if the pod is ready.
  4. Execute the integration tests. Provide the URL of the Red Hat SSO server as a parameter:

    $ mvn clean verify -Popenshift,openshift-it -DSSO_AUTH_SERVER_URL=$(oc get route secure-sso -o jsonpath='{"https://"}{.spec.host}{"/auth\n"}')
  5. Once the tests are finished, remove the Red Hat SSO server:

    oc delete -f service.sso.yaml

3.6.10. Secured SSO resources

Follow the links below for additional information on the principles behind the OAuth2 specification and on securing your applications using Red Hat SSO and Keycloak:

3.7. Cache example for Thorntail

Limitation: Run this example application on a Minishift or CDK. You can also use a manual workflow to deploy this example to OpenShift Online Pro and OpenShift Container Platform. This example is not currently available on OpenShift Online Starter.

Example proficiency level: Advanced.

The Cache example demonstrates how to use a cache to increase the response time of applications.

This example shows you how to:

  • Deploy a cache to OpenShift.
  • Use a cache within an application.

3.7.1. How caching works and when you need it

Caches allows you to store information and access it for a given period of time. You can access information in a cache faster or more reliably than repeatedly calling the original service. A disadvantage of using a cache is that the cached information is not up to date. However, that problem can be reduced by setting an expiration or TTL (time to live) on each value stored in the cache.

Example 3.3. Caching example

Assume you have two applications: service1 and service2:

  • Service1 depends on a value from service2.

    • If the value from service2 infrequently changes, service1 could cache the value from service2 for a period of time.
    • Using cached values can also reduce the number of times service2 is called.
  • If it takes service1 500 ms to retrieve the value directly from service2, but 100 ms to retrieve the cached value, service1 would save 400 ms by using the cached value for each cached call.
  • If service1 would make uncached calls to service2 5 times per second, over 10 seconds, that would be 50 calls.
  • If service1 started using a cached value with a TTL of 1 second instead, that would be reduced to 10 calls over 10 seconds.

How the Cache example works

  1. The cache, cute name, and greeting services are deployed and exposed.
  2. User accesses the web frontend of the greeting service.
  3. User invokes the greeting HTTP API using a button on the web frontend.
  4. The greeting service depends on a value from the cute name service.

    • The greeting service first checks if that value is stored in the cache service. If it is, then the cached value is returned.
    • If the value is not cached, the greeting service calls the cute name service, returns the value, and stores the value in the cache service with a TTL of 5 seconds.
  5. The web front end displays the response from the greeting service as well as the total time of the operation.
  6. User invokes the service multiple times to see the difference between cached and uncached operations.

    • Cached operations are significantly faster than uncached operations.
    • User can force the cache to be cleared before the TTL expires.

3.7.2. Viewing the example application source code and README

Prerequisites

One of the following:

  • Access to developers.redhat.com/launch
  • Fabric8 Launcher installed on a Minishift or CDK

Procedure

  1. Use the Fabric8 Launcher tool to generate your own version of the example application.
  2. View the generated GitHub repository or download and extract the ZIP file that contains the example application source code.

3.7.3. Deploying the Cache example application to OpenShift Online

Use one of the following options to execute the Cache example application on OpenShift Online.

Although each method uses the same oc commands to deploy your application, using developers.redhat.com/launch provides an automated deployment workflow that executes the oc commands for you.

3.7.3.1. Deploying the example application using developers.redhat.com/launch

Prerequisites

Procedure

  1. Navigate to the developers.redhat.com/launch URL in a browser and log in.
  2. Follow on-screen instructions to create and launch your example application in Thorntail.

3.7.3.2. Authenticating the oc CLI client

  4. Find the text box that contains the oc login …​ command with the hidden token, and click the button next to it to copy its content to your clipboard.
  5. Paste the command into a terminal application. The command uses your authentication token to authenticate your oc CLI client with your OpenShift Online account.

    $ oc login OPENSHIFT_URL --token=MYTOKEN

3.7.3.3. Deploying the Cache example application using the oc CLI client

Prerequisites

Procedure

  1. Clone your project from GitHub.

    $ git clone git@github.com:USERNAME/MY_PROJECT_NAME.git

    Alternatively, if you downloaded a ZIP file of your project, extract it.

    $ unzip MY_PROJECT_NAME.zip
  2. Create a new project.

    $ oc new-project MY_PROJECT_NAME
  3. Navigate to the root directory of your application.
  4. Deploy the cache service.

    $ oc apply -f service.cache.yml
  5. Use Maven to start the deployment to OpenShift.

    $ mvn clean fabric8:deploy -Popenshift
  6. Check the status of your application and ensure your pod is running.

    $ oc get pods -w
    NAME                             READY     STATUS      RESTARTS   AGE
    cache-server-123456789-aaaaa             1/1       Running     0          8m
    MY_APP_NAME-cutename-1-bbbbb       1/1       Running     0          4m
    MY_APP_NAME-cutename-s2i-1-build   0/1       Completed   0          7m
    MY_APP_NAME-greeting-1-ccccc       1/1       Running     0          3m
    MY_APP_NAME-greeting-s2i-1-build   0/1       Completed   0          3m

    Your 3 pods should have a status of Running once they are fully deployed and started.

  7. After your example application is deployed and started, determine its route.

    Example Route Information

    $ oc get routes
    NAME                 HOST/PORT                                                     PATH      SERVICES        PORT      TERMINATION
    MY_APP_NAME-cutename   MY_APP_NAME-cutename-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME             MY_APP_NAME-cutename   8080                    None
    MY_APP_NAME-greeting   MY_APP_NAME-greeting-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME             MY_APP_NAME-greeting   8080                    None

    The route information of a pod gives you the base URL which you use to access it. In the example above, you would use http://MY_APP_NAME-greeting-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME as the base URL to access the greeting service.

3.7.4. Deploying the Cache example application to Minishift or CDK

Use one of the following options to execute the Cache example application locally on Minishift or CDK:

Although each method uses the same oc commands to deploy your application, using Fabric8 Launcher provides an automated deployment workflow that executes the oc commands for you.

3.7.4.1. Getting the Fabric8 Launcher tool URL and credentials

You need the Fabric8 Launcher tool URL and user credentials to create and deploy example applications on Minishift or CDK. This information is provided when the Minishift or CDK is started.

Prerequisites

Procedure

  1. Navigate to the console where you started Minishift or CDK.
  2. Check the console output for the URL and user credentials you can use to access the running Fabric8 Launcher:

    Example Console Output from a Minishift or CDK Startup

    ...
    -- Removing temporary directory ... OK
    -- Server Information ...
       OpenShift server started.
       The server is accessible via web console at:
           https://192.168.42.152:8443
    
       You are logged in as:
           User:     developer
           Password: developer
    
       To login as administrator:
           oc login -u system:admin

  1. Navigate to the Fabric8 Launcher URL in a browser.
  2. Follow the on-screen instructions to create and launch your example application in Thorntail.

3.7.4.3. Authenticating the oc CLI client

To work with example applications on Minishift or CDK using the oc command-line client, you must authenticate the client using the token provided by the Minishift or CDK web interface.

Prerequisites

Procedure

  1. Navigate to the Minishift or CDK URL in a browser.
  2. Click on the question mark icon in the top right-hand corner of the Web console, next to your user name.
  3. Select Command Line Tools in the drop-down menu.
  4. Find the text box that contains the oc login …​ command with the hidden token, and click the button next to it to copy its content to your clipboard.
  5. Paste the command into a terminal application. The command uses your authentication token to authenticate your oc CLI client with your Minishift or CDK account.

    $ oc login OPENSHIFT_URL --token=MYTOKEN

3.7.4.4. Deploying the Cache example application using the oc CLI client

Prerequisites

Procedure

  1. Clone your project from GitHub.

    $ git clone git@github.com:USERNAME/MY_PROJECT_NAME.git

    Alternatively, if you downloaded a ZIP file of your project, extract it.

    $ unzip MY_PROJECT_NAME.zip
  2. Create a new project.

    $ oc new-project MY_PROJECT_NAME
  3. Navigate to the root directory of your application.
  4. Deploy the cache service.

    $ oc apply -f service.cache.yml
  5. Use Maven to start the deployment to OpenShift.

    $ mvn clean fabric8:deploy -Popenshift
  6. Check the status of your application and ensure your pod is running.

    $ oc get pods -w
    NAME                             READY     STATUS      RESTARTS   AGE
    cache-server-123456789-aaaaa             1/1       Running     0          8m
    MY_APP_NAME-cutename-1-bbbbb       1/1       Running     0          4m
    MY_APP_NAME-cutename-s2i-1-build   0/1       Completed   0          7m
    MY_APP_NAME-greeting-1-ccccc       1/1       Running     0          3m
    MY_APP_NAME-greeting-s2i-1-build   0/1       Completed   0          3m

    Your 3 pods should have a status of Running once they are fully deployed and started.

  7. After your example application is deployed and started, determine its route.

    Example Route Information

    $ oc get routes
    NAME                 HOST/PORT                                                     PATH      SERVICES        PORT      TERMINATION
    MY_APP_NAME-cutename   MY_APP_NAME-cutename-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME             MY_APP_NAME-cutename   8080                    None
    MY_APP_NAME-greeting   MY_APP_NAME-greeting-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME             MY_APP_NAME-greeting   8080                    None

    The route information of a pod gives you the base URL which you use to access it. In the example above, you would use http://MY_APP_NAME-greeting-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME as the base URL to access the greeting service.

3.7.5. Deploying the Cache example application to OpenShift Container Platform

The process of creating and deploying example applications to OpenShift Container Platform is similar to OpenShift Online:

Prerequisites

Procedure

3.7.6. Interacting with the unmodified Cache example application

Prerequisites

  • Your application deployed

Procedure

  1. Navigate to the greeting service using your browser.
  2. Click Invoke the service once.

    Notice the duration value is above 2000. Also notice the cache state has changed form No cached value to A value is cached.

  3. Wait 5 seconds and notice cache state has changed back to No cached value.

    The TTL for the cached value is set to 5 seconds. When the TTL expires, the value is no longer cached.

  4. Click Invoke the service once more to cache the value.
  5. Click Invoke the service a few more times over the course of a few seconds while cache state is A value is cached.

    Notice a significantly lower duration value since it is using a cached value. If you click Clear the cache, the cache is emptied.

3.7.7. Running the Cache example application integration tests

This example application includes a self-contained set of integration tests. When run inside an OpenShift project, the tests:

  • Deploy a test instance of the application to the project.
  • Execute the individual tests on that instance.
  • Remove all instances of the application from the project when the testing is done.
Warning

Executing integration tests removes all existing instances of the example application from the target OpenShift project. To avoid accidentally removing your example application, ensure that you create and select a separate OpenShift project to execute the tests.

Prerequisites

  • The oc client authenticated
  • An empty OpenShift project

Procedure

Execute the following command to run the integration tests:

$ mvn clean verify -Popenshift,openshift-it

3.7.8. Caching resources

More background and related information on caching can be found here:

Chapter 4. Developing and deploying Thorntail application

In addition to using an example, you can create new Thorntail applications from scratch and deploy them to OpenShift.

4.1. Creating an application from scratch

Creating a simple Thorntail–based application with a REST endpoint from scratch.

Prerequisites

  • OpenJDK 8 or OpenJDK 11 installed
  • Maven 3.5.0 installed

Procedure

  1. Create a directory for the application and navigate to it:

    $ mkdir myApp
    $ cd myApp

    We recommend you start tracking the directory contents with Git. For more information, see Git tutorial.

  2. In the directory, create a pom.xml file with the following content.

    <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      </pluginRepositories>
    
    </project>
  3. Create a directory structure for your application:

    mkdir -p src/main/java/com/example/rest
  4. In the src/main/java/com/example/rest directory, create the source files:

    • HelloWorldEndpoint.java with the class that serves the HTTP endpoint:

      package com.example.rest;
      
      import javax.ws.rs.Path;
      import javax.ws.rs.core.Response;
      import javax.ws.rs.GET;
      import javax.ws.rs.Produces;
      
      @Path("/hello")
      public class HelloWorldEndpoint {
      
        @GET
        @Produces("text/plain")
        public Response doGet() {
          return Response.ok("Hello from Thorntail!").build();
        }
      }
    • RestApplication.java with the application context:

      package com.example.rest;
      
      import javax.ws.rs.core.Application;
      import javax.ws.rs.ApplicationPath;
      
      @ApplicationPath("/rest")
      public class RestApplication extends Application {
      }
  5. Execute the application using Maven:

    $ mvn thorntail:run

Results

Accessing the http://localhost:8080/rest/hello URL in your browser should return the following message:

Hello from Thorntail!

After finishing the procedure, there should be a directory on your hard drive with the following contents:

myApp
├── pom.xml
└── src
    └── main
        └── java
            └── com
                └── example
                    └── rest
                        ├── HelloWorldEndpoint.java
                        └── RestApplication.java

4.2. Deploying Thorntail application to OpenShift

To deploy your Thorntail application to OpenShift, configure the pom.xml file in your application and then deploy using the Fabric8 Maven plugin.

4.2.1. Preparing Thorntail application for OpenShift deployment

For deploying your Thorntail application to OpenShift, it must contain:

  • Launcher profile information in the application’s pom.xml file.

In the following procedure, a profile with Fabric8 Maven plugin is used for building and deploying the application to OpenShift.

Prerequisites

  • Maven is installed.

Procedure

  1. Add the following content to the pom.xml file in the application root directory:

    ...
    
    <profiles>
        <profile>
          <id>openshift</id>
          <build>
            <plugins>
              <plugin>
                <groupId>io.fabric8</groupId>
                <artifactId>fabric8-maven-plugin</artifactId>
                <version>4.1.0</version>
                <executions>
                  <execution>
                    <goals>
                      <goal>resource</goal>
                      <goal>build</goal>
                    </goals>
                  </execution>
                </executions>
              </plugin>
            </plugins>
          </build>
        </profile>
      </profiles>

4.2.2. Deploying Thorntail application to OpenShift using Fabric8 Maven plugin

To deploy your Thorntail application to OpenShift, you must perform the following:

  • Log in to your OpenShift instance.
  • Deploy the application to the OpenShift instance.

Prerequisites

  • oc CLI client installed.
  • Maven installed.

Procedure

  1. Log in to your OpenShift instance with the oc client.

    $ oc login ...
  2. Create a new project in the OpenShift instance.

    $ oc new-project MY_PROJECT_NAME
  3. Deploy the application to OpenShift using Maven from the application’s root directory. The root directory of an application contains the pom.xml file.

    $ mvn clean fabric8:deploy -Popenshift

    This command uses the Fabric8 Maven Plugin to launch the S2I process on OpenShift and start the pod.

  4. Verify the deployment.

    1. Check the status of your application and ensure your pod is running.

      $ oc get pods -w
      NAME                             READY     STATUS      RESTARTS   AGE
      MY_APP_NAME-1-aaaaa               1/1       Running     0          58s
      MY_APP_NAME-s2i-1-build           0/1       Completed   0          2m

      The MY_APP_NAME-1-aaaaa pod should have a status of Running once it is fully deployed and started.

      Your specific pod name will vary.

    2. Determine the route for the pod.

      Example Route Information

      $ oc get routes
      NAME                 HOST/PORT                                                     PATH      SERVICES        PORT      TERMINATION
      MY_APP_NAME         MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME      MY_APP_NAME      8080

      The route information of a pod gives you the base URL which you use to access it.

      In this example, http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME is the base URL to access the application.

    3. Verify that your application is running in OpenShift.

      $ curl http://MY_APP_NAME-MY_PROJECT_NAME.OPENSHIFT_HOSTNAME/rest/hello
      Hello from Thorntail!

4.3. Deploying Thorntail application to standalone Red Hat Enterprise Linux

To deploy your Thorntail application to standalone Red Hat Enterprise Linux, configure the pom.xml file in the application, package it using Maven and deploy using the java -jar command.

Prerequisites

    $ curl http://localhost:8080

Chapter 5. Using Thorntail Maven Plugin

Thorntail provides a Maven plugin to accomplish most of the work of building uberjar packages.

5.1. Thorntail Maven plugin general usage

The Thorntail Maven plugin is used like any other Maven plugin, that is through editing the pom.xml file in your application and adding a <plugin> section:

<plugin>
  <groupId>io.thorntail</groupId>
  <artifactId>thorntail-maven-plugin</artifactId>
  <version>${version.thorntail}</version>
  <executions>
    ...
    <execution>
      <goals>
        ...
      </goals>
      <configuration>
        ...
      </configuration>
    </execution>
  </executions>
</plugin>

5.2. Thorntail Maven plugin goals

The Thorntail Maven plugin provides several goals:

package
Creates the executable package (see Section 8.2, “Creating an uberjar”).
run
Executes your application in the Maven process. The application is stopped if the Maven build is interrupted, for example when you press Ctrl + C.
start and multistart
Executes your application in a forked process. Generally, it is only useful for running integration tests using a plugin, such as the maven-failsafe-plugin. The multistart variant allows starting multiple Thorntail–built applications using Maven GAVs to support complex testing scenarios.
stop

Stops any previously started applications.

Note

The stop goal can only stop applications that were started in the same Maven execution.

5.3. Thorntail Maven plugin configuration options

The Thorntail Maven plugin accepts the following configuration options:

bundleDependencies

If true, dependencies are included in the -thorntail.jar file. Otherwise, they are resolved from $M2_REPO or from the network at runtime.

Property

thorntail.bundleDependencies

Default

true

Used by

package

debug

The port to use for debugging. If set, the Thorntail process suspends on start and opens a debugger on this port.

Property

thorntail.debug.port

Default

 

Used by

run, start

environment

A properties-style list of environment variables to use when executing the application.

Property

none

Default

 

Used by

multistart, run, start

environmentFile

A .properties file with environment variables to use when executing the application.

Property

thorntail.environmentFile

Default

 

Used by

multistart, run, start

filterWebInfLib

If true, the plugin removes artifacts that are provided by the Thorntail runtime from the WEB-INF/lib directory of the project WAR file. Otherwise, the contents of WEB-INF/lib remain untouched.

Property

thorntail.filterWebInfLib

Default

true

Used by

package

Note

This option is generally not necessary and is provided as a workaround in case the Thorntail plugin removes a dependency required by the application. When false, it is the responsibility of the developer to ensure that the WEB-INF/lib directory does not contain Thorntail artifacts that would compromise the functionality of the application. One way to do that is to avoid expressing dependencies on fractions and rely on auto-detection or by explicitly listing any required extra fractions using the fractions option.

fractionDetectMode

The mode of fraction detection. The available options are:

  • when_missing: Runs only when no Thorntail dependencies are found.
  • force: Always run, and merge any detected fractions with the existing dependencies. Existing dependencies take precedence.
  • never: Disable fraction detection.

Property

thorntail.detect.mode

Default

when_missing

Used by

package, run, start

fractions

A list of extra fractions to include when using auto-detection. It is useful for fractions that cannot be detected or for user-provided fractions.

Use one of the following formats when specifying a fraction: * group:artifact:version * artifact:version * artifact

If no group is provided, io.thorntail is assumed.

If no version is provided, the version is taken from the Thorntail BOM for the version of the plugin you are using.

If the value starts with a ! character, the corresponding auto-detected fraction is not installed (unless it is a dependency of any other fraction). In the following example the Undertow fraction is not installed even though your application references a class from the javax.servlet package:

<plugin>
  <groupId>io.thorntail</groupId>
  <artifactId>thorntail-maven-plugin</artifactId>
  <version>${version.thorntail}</version>
  <executions>
    <execution>
      <goals>
        <goal>package</goal>
      </goals>
      <configuration>
       <fractions>
         <fraction>!undertow</fraction>
       </fractions>
      </configuration>
    </execution>
  </executions>
</plugin>

stdoutFile

Specifies the path to a file where the stdout output is stored instead of being sent to the stdout output of the launching process.

Property

thorntail.stdout

Default

 

Used by

run, start

useUberJar

If specified, the -thorntail.jar file located in ${project.build.directory} is used. This JAR is not created automatically, so make sure you execute the package goal first.

Property

thorntail.useUberJar

Default

 

Used by

run, start

Note

Before version 2.3.0.Final, this property was called wildfly-swarm.useUberJar, and only setting it to true enabled this behavior: -Dwildfly-swarm.useUberJar=true. You can continue using the old name in later releases, but consider using the new variant, which no longer requires you to set a value: -Dthorntail.useUberJar.

5.4. Thorntail Maven plugin configuration properties

Properties can be used to configure the execution and affect the packaging or running of your application.

If you add a <properties> or <propertiesFile> section to the <configuration> of the plugin, the properties are used when executing your application using the mvn thorntail:run command. In addition to that, the same properties are added to your myapp-thorntail.jar file to affect subsequent executions of the uberjar. Any properties loaded from the <propertiesFile> override identically-named properties in the <properties> section.

Any properties added to the uberjar can be overridden at runtime using the traditional -Dname=value mechanism of the java binary, or using the YAML-based configuration files.

Only the following properties are added to the uberjar at package time:

  • The properties specified outside of the <properties> section or the <propertiesFile>, whose path starts with one of the following:

    • jboss.
    • wildfly.
    • thorntail.
    • swarm.
    • maven.
  • The properties that override a property specified in the <properties> section or the <propertiesFile>.

Chapter 6. Fractions

Thorntail is defined by an unbounded set of capabilities. Each piece of functionality is called a fraction. Some fractions provide only access to APIs, such as JAX-RS or CDI; other fractions provide higher-level capabilities, such as integration with RHSSO (Keycloak).

The typical method for consuming Thorntail fractions is through Maven coordinates, which you add to the pom.xml file in your application. The functionality the fraction provides is then packaged with your application (see Section 8.2, “Creating an uberjar”).

To enable easier consumption of Thorntail fractions, a bill of materials (BOM) is available. For more information, see Chapter 7, Using a BOM.

6.1. Auto-detecting fractions

Migrating existing legacy applications to benefit from Thorntail is simple when using fraction auto-detection. If you enable the Thorntail Maven plugin in your application, Thorntail detects which APIs you use, and includes the appropriate fractions at build time.

Note

By default, Thorntail only auto-detects if you do not specify any fractions explicitly. This behavior is controlled by the fractionDetectMode property. For more information, see the Maven plugin configuration reference.

For example, consider your pom.xml already specifies the API .jar file for a specification such as JAX-RS:

<dependencies>
    <dependency>
      <groupId>org.jboss.spec.javax.ws.rs</groupId>
      <artifactId>jboss-jaxrs-api_2.1_spec</artifactId>
      <version>${version.jaxrs-api}</version>
      <scope>provided</scope>
    </dependency>
</dependencies>

Thorntail then includes the jaxrs fraction during the build automatically.

Prerequisites

  • An existing Maven-based application with a pom.xml file.

Procedure

  1. Add the thorntail-maven-plugin to your pom.xml in a <plugin> block, with an <execution> specifying the package goal.

    <plugins>
      <plugin>
        <groupId>io.thorntail</groupId>
        <artifactId>thorntail-maven-plugin</artifactId>
        <version>${version.thorntail}</version>
        <executions>
          <execution>
            <id>package</id>
            <goals>
              <goal>package</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  2. Perform a normal Maven build:

    $ mvn package
  3. Execute the resulting uberjar:

    $ java -jar ./target/myapp-thorntail.jar

6.2. Using explicit fractions

When writing your application from scratch, ensure it compiles correctly and uses the correct version of APIs by explicitly selecting which fractions are packaged with it.

Prerequisites

  • A Maven-based application with a pom.xml file.

Procedure

  1. Add the BOM to your pom.xml. For more information, see Chapter 7, Using a BOM.
  2. Add the Thorntail Maven plugin to your pom.xml. For more information, see Section 8.2, “Creating an uberjar”.
  3. Add one or more dependencies on Thorntail fractions to the pom.xml file:

    <dependencies>
      <dependency>
        <groupId>io.thorntail</groupId>
        <artifactId>jaxrs</artifactId>
      </dependency>
    </dependencies>
  4. Perform a normal Maven build:

    $ mvn package
  5. Execute the resulting uberjar:

    $ java -jar ./target/myapp-thorntail.jar

Chapter 7. Using a BOM

To explicitly specify the Thorntail fractions your application uses, instead of relying on auto-detection, Thorntail includes a set of BOMs (bill of materials) which you can use instead of having to track and update Maven artifact versions in several places.

7.1. Thorntail product BOM types

Thorntail is described as just enough app-server, which means it consists of multiple pieces. Your application includes only the pieces it needs.

When using the Thorntail product, you can specify the following Maven BOMs:

bom
All fractions available in the product.
bom-certified
All community fractions that have been certified against the product. Any fraction used from bom-certified is unsupported.

7.2. Specifying a BOM for in your application

Importing a specific BOM in the pom.xml file in your application allows you to track all your application dependencies in one place.

Note

One shortcoming of importing a Maven BOM import is that it does not handle the configuration on the level of <pluginManagement>. When you use the Thorntail Maven Plugin, you must specify the version of the plugin to use.

Thanks to the property you use in your pom.xml file, you can easily ensure that your plugin usage matches the release of Thorntail that you are targeting with the BOM import.

<plugins>
  <plugin>
    <groupId>io.thorntail</groupId>
    <artifactId>thorntail-maven-plugin</artifactId>
    <version>${version.thorntail}</version>
      ...
  </plugin>
</plugins>

Prerequisites

  • Your application as a Maven-based project with a pom.xml file.

Procedure

  1. Include a bom artifact in your pom.xml.

    Tracking the current version of Thorntail through a property in your pom.xml is recommended.

    <properties>
      <version.thorntail>2.4.0.Final-redhat-00013</version.thorntail>
    </properties>

    Import BOMs in the <dependencyManagement> section. Specify the <type>pom</type> and <scope>import</scope>.

    <dependencyManagement>
      <dependencies>
        <dependency>
          <groupId>io.thorntail</groupId>
          <artifactId>bom</artifactId>
          <version>${version.thorntail}</version>
          <type>pom</type>
          <scope>import</scope>
        </dependency>
      </dependencies>
    </dependencyManagement>

    In the example above, the bom artifact is imported to ensure that only stable fractions are available.

    By including the BOMs of your choice in the <dependencyManagement> section, you have:

    • Provided version-management for any Thorntail artifacts you subsequently choose to use.
    • Provided support to your IDE for auto-completing known artifacts when you edit your the pom.xml file of your application.
  2. Include Thorntail dependencies.

    Even though you imported the Thorntail BOMs in the <dependencyManagement> section, your application still has no dependencies on Thorntail artifacts.

    To include Thorntail artifact dependencies based on the capabilities your application, enter the relevant artifacts as <dependency> elements:

    Note

    You do not have to specify the version of the artifacts because the BOM imported in <dependencyManagement> handles that.

    <dependencies>
      <dependency>
        <groupId>io.thorntail</groupId>
        <artifactId>jaxrs</artifactId>
      </dependency>
      <dependency>
        <groupId>io.thorntail</groupId>
        <artifactId>datasources</artifactId>
      </dependency>
    </dependencies>

    In the example above, we include explicit dependencies on the jaxrs and datasources fractions, which will provide transitive inclusion of others, for example undertow.

7.3. Logging

7.3.1. Enabling logging

Each Thorntail fraction is dependent on the Logging fraction, which means that if you use any Thorntail fraction in your application, logging is automatically enabled on the INFO level and higher. If you want to enable logging explicitly, add the Logging fraction to the POM file of your application.

Prerequisites

  • A Maven-based application

Procedure

  1. Find the <dependencies> section in the pom.xml file of your application. Verify it contains the following coordinates. If it does not, add them.

    <dependency>
      <groupId>io.thorntail</groupId>
      <artifactId>logging</artifactId>
    </dependency>
  2. If you want to log messages of a level other than INFO, launch the application while specifying the thorntail.logging system property:

    $ mvn thorntail:run -Dthorntail.logging=FINE

    See the org.wildfly.swarm.config.logging.Level class for the list of available levels.

7.3.2. Logging to a file

In addition to the console logging, you can save the logs of your application in a file. Typically, deployments use rotating logs to save disk space.

In Thorntail, logging is configured using system properties. Even though it is possible to use the -Dproperty=value syntax when launching your application, it is strongly recommended to configure file logging using the YAML profile files.

Prerequisites
Procedure
  1. Open a YAML profile file of your choice. If you do not know which one to use, open project-defaults.yml in the src/main/resources directory in your application sources. In the YAML file, add the following section:

    thorntail:
      logging:
  2. Configure a formatter (optional). The following formatters are configured by default:

    PATTERN
    Useful for logging into a file.
    COLOR_PATTERN
    Color output. Useful for logging to the console.

    To configure a custom formatter, add a new formatter with a pattern of your choice in the logging section. In this example, it is called LOG_FORMATTER:

    pattern-formatters:
      LOG_FORMATTER:
        pattern: "%p [%c] %s%e%n"
  3. Configure a file handler to use with the loggers. This example shows the configuration of a periodic rotating file handler. Under logging, add a periodic-rotating-file-handlers section with a new handler.

    periodic-rotating-file-handlers:
      FILE:
        file:
          path: target/MY_APP_NAME.log
        suffix: .yyyy-MM-dd
        named-formatter: LOG_FORMATTER
        level: INFO

    Here, a new handler named FILE is created, logging events of the INFO level and higher. It logs in the target directory, and each log file is named MY_APP_NAME.log with the suffix .yyyy-MM-dd. Thorntail automatically parses the log rotation period from the suffix, so ensure you use a format compatible with the java.text.SimpleDateFormat class.

  4. Configure the root logger.

    The root logger is by default configured to use the CONSOLE handler only. Under logging, add a root-logger section with the handlers you wish to use:

    root-logger:
      handlers:
      - CONSOLE
      - FILE

    Here, the FILE handler from the previous step is used, along with the default console handler.

Below, you can see the complete logging configuration section:

The logging section in a YAML configuration profile

thorntail:
  logging:
    pattern-formatters:
      LOG_FORMATTER:
        pattern: "CUSTOM LOG FORMAT %p [%c] %s%e%n"
    periodic-rotating-file-handlers:
      FILE:
        file:
          path: path/to/your/file.log
        suffix: .yyyy-MM-dd
        named-formatter: LOG_FORMATTER
    root-logger:
      handlers:
      - CONSOLE
      - FILE

7.4. Configuring a Thorntail application

You can configure numerous options with applications built with Thorntail. For most options, reasonable defaults are already applied, so you do not have to change any options unless you explicitly want to.

This reference is a complete list of all configurable items, grouped by the fraction that introduces them. Only the items related to the fractions that your application uses are relevant to you.

7.4.1. System properties

Using system properties for configuring your application is advantageous for experimenting, debugging, and other short-term activities.

7.4.1.1. Commonly used system properties

This is a non-exhaustive list of system properties you are likely to use in your application:

General system properties

thorntail.bind.address

The interface to bind servers

Default

0.0.0.0

thorntail.port.offset

The global port adjustment

Default

0

thorntail.context.path

The context path for the deployed application

Default

/

thorntail.http.port

The port for the HTTP server

Default

8080

thorntail.https.port

The port for the HTTPS server

Default

8483

thorntail.debug.port

If provided, the Thorntail process will pause for debugging on the given port.

This option is only available when running an Arquillian test or starting the application using the mvn thorntail:run command, not when executing a JAR file. The JAR file execution requires normal Java debug agent parameters.

Default

 

Datasource-related system properties

With JDBC driver autodetection, use the following properties to configure the datasource:

thorntail.ds.name

The name of the datasource

Default

ExampleDS

thorntail.ds.username

The user name to access the database

Default

driver-specific

thorntail.ds.password

The password to access the database

Default

driver-specific

thorntail.ds.connection.url

The JDBC connection URL

Default

driver-specific

Note

For a full set of available properties, see the documentation for each fraction and the javadocs on class SwarmProperties.java

7.4.1.2. Application configuration using system properties

Configuration properties are presented using dotted notation, and are suitable for use as Java system property names, which your application consumes through explicit setting in the Maven plugin configuration, or through the command line when your application is being executed.

Any property that has the KEY parameter in its name indicates that you must supply a key or identifier in that segment of the name.

Configuration of items with the KEY parameter

A configuration item documented as thorntail.undertow.servers.KEY.default-host indicates that the configuration applies to a particular named server.

In practical usage, the property would be, for example, thorntail.undertow.servers.default.default-host for a server known as default.

7.4.1.3. Setting system properties using the Maven plugin

Setting properties using the Maven plugin is useful for temporarily changing a configuration item for a single execution of your Thorntail application.

Note

Even though the configuration in the POM file of your application is persistent, it is not recommended to use it for long-term configuration of your application. Instead, use the YAML configuration files.

If you want to set explicit configuration values as defaults through the Maven plugin, add a <properties> section to the <configuration> block of the plugin in the pom.xml file in your application.

Prerequisites
  • Your Thorntail-based application with a POM file
Procedure
  1. In the POM file of your application, locate the configuration you want to modify.
  2. Insert a block with configuration of the io.thorntail:thorntail-maven-plugin artifact, for example:

    <build>
      <plugins>
        <plugin>
          <groupId>io.thorntail</groupId>
          <artifactId>thorntail-maven-plugin</artifactId>
          <version>2.4.0.Final-redhat-00013</version>
          <configuration>
            <properties>
              <thorntail.bind.address>127.0.0.1</thorntail.bind.address>
              <java.net.preferIPv4Stack>true</java.net.preferIPv4Stack>
            </properties>
          </configuration>
        </plugin>
      </plugins>
    </build>

    In the example above, the thorntail.bind.address property is set to 127.0.0.1 and the java.net.preferIPv4Stack property is set to true.

7.4.1.4. Setting system properties using the command line

Setting properties using the Maven plugin is useful for temporarily changing a configuration item for a single execution of your Thorntail application.

You can customize an environment-specific setting or experiment with configuration items before setting them in a YAML configuration file.

To use a property on the command line, pass it as a command-line parameter to the Java binary:

Prerequisites
  • A JAR file with your application
Procedure
  1. In a terminal application, navigate to the directory with your application JAR file.
  2. Execute your application JAR file using the Java binary and specify the property and its value:

    $ java -Dthorntail.bind.address=127.0.0.1 -jar myapp-thorntail.jar

    In this example, you assing the value 127.0.0.1 to the property called thorntail.bind.address.

7.4.1.5. Specifying JDBC drivers for hollow JARs

When executing a hollow JAR, you can specify a JDBC Driver JAR using the thorntail.classpath property. This way, you do not need to package the driver in the hollow JAR.

The thorntail.classpath property accepts one or more paths to JAR files separated by ; (a semicolon). The specified JAR files are added to the classpath of the application.

Prerequisites
  • A JAR file with your application
Procedure
  1. In a terminal application, navigate to the directory with your application JAR file.
  2. Execute your application JAR file using the Java binary and specify the JDBC driver:

    $ java -Dthorntail.classpath=./h2-1.4.196.jar -jar microprofile-jpa-hollow-thorntail.jar example-jpa-jaxrs-cdi.war

7.4.2. Environment Variables

Use environment variables to configure your application or override values stored in YAML files.

7.4.2.1. Application configuration using environment variables

Use environment variables to configure your application in various deployments—​especially in a containerized environment, such as Docker.

Example 7.1. Environment variables configuration

A property documented as thorntail.undertow.servers.KEY.default-host translates to the following environment variable (substituting the KEY segment with the default identifier):

export THORNTAIL.UNDERTOW.SERVERS.DEFAULT.DEFAULT_DASH_HOST=<myhost>

Unlike other configuration options, properties defined as environment variables in Linux-based containers do not allow defining non-alphanumeric characters like dot (.), dash/hyphen (-) or any other characters not in the [A-Za-z0-9_] range. Many configuration properties in Thorntail contain these characters, so you must follow these rules when defining the environment variables in the following environments:

Linux-based container rules

  • It is a naming convention that all environment properties are defined using uppercase letters. For example, define the serveraddress property as SERVERADDRESS.
  • All the dot (.) characters must be replaced with underscore (_). For example, define the thorntail.bind.address=127.0.0.1 property as THORNTAIL_BIND_ADDRESS=127.0.0.1.
  • All dash/hyphen (-) characters must be replaced with the _DASH_ string. For example, define the thorntail.data-sources.foo.url=<url> property as THORNTAIL_DATA_DASH_SOURCES_FOO_URL=<url>.
  • If the property name contains underscores, all underscore (_) characters must be replaced with the _UNDERSCORE_ string. For example, define the thorntail.data_sources.foo.url=<url> property as THORNTAIL_DATA_UNDERSCORE_SOURCES_FOO_URL=<url>.

Example 7.2. An example data source configuration

System property

-Dthorntail.datasources.data-sources.devwf.connection-url= jdbc:postgresql://localhost:5432/sampledb

Env. variable

THORNTAIL_DATASOURCES_DATA_DASH_SOURCES_DEVWF_CONNECTION_DASH_URL= 'jdbc:postgresql://localhost:5432/sampledb'

System property

-Dthorntail.datasources.data-sources.devwf.driver-name=postgresql

Env. variable

THORNTAIL_DATASOURCES_DATA_DASH_SOURCES_DEVWF_DRIVER_DASH_NAME='postgresql'

System property

-Dthorntail.datasources.data-sources.devwf.jndiname=java:/jboss/datasources/devwf

Env. variable

THORNTAIL_DATASOURCES_DATA_DASH_SOURCES_DEVWF_JNDI_DASH_NAME='java:/jboss/datasources/devwf'

System property

-Dthorntail.datasources.data-sources.devwf.user-name=postgres

Env. variable

THORNTAIL_DATASOURCES_DATA_DASH_SOURCES_DEVWF_USER_DASH_NAME='postgres'

System property

-Dthorntail.datasources.data-sources.devwf.password=admin

Env. variable

THORNTAIL_DATASOURCES_DATA_DASH_SOURCES_DEVWF_PASSWORD='admin'

7.4.3. YAML files

YAML is the preferred method for long-term configuration of your application. In addition to that, the YAML strategy provides grouping of environment-specific configurations, which you can selectively enable when executing the application.

7.4.3.1. The general YAML file format

The Thorntail configuration item names correspond to the YAML configuration structure.

Example 7.3. YAML configuration

For example, a configuration item documented as thorntail.undertow.servers.KEY.default-host translates to the following YAML structure, substituting the KEY segment with the default identifier:

thorntail:
  undertow:
    servers:
      default:
        default-host: <myhost>

7.4.3.2. Default Thorntail YAML Files

By default, Thorntail looks up permanent configuration in files with specific names to put on the classpath.

project-defaults.yml

If the original .war file with your application contains a file named project-defaults.yml, that file represents the defaults applied over the absolute defaults that Thorntail provides.

Other default file names

In addition to the project-defaults.yml file, you can provide specific configuration files using the -S <name> command-line option. The specified files are loaded, in the order you provided them, before project-defaults.yml. A name provided in the -S <name> argument specifies the project-<name>.yml file on your classpath.

Example 7.4. Specifying configuration files on the command line

Consider the following application execution:

$ java -jar myapp-thorntail.jar -Stesting -Scloud

The following YAML files are loaded, in this order. The first file containing a given configuration item takes precedence over others:

  1. project-testing.yml
  2. project-cloud.yml
  3. project-defaults.yml

7.4.3.3. Non-default Thorntail YAML configuration files

In addition to default configuration files for your Thorntail-based application, you can specify YAML files outside of your application. Use the -s <path> command-line option to load the desired file.

Both the -s <path> and -S <name> command-line options can be used at the same time, but files specified using the -s <path> option take precedence over YAML files contained in your application.

Example 7.5. Specifying configuration files inside and outside of the application

Consider the following application execution:

$ java -jar myapp-thorntail.jar -s/home/app/openshift.yml -Scloud -Stesting

The following YAML files are loaded, in this order:

  1. /home/app/openshift.yml
  2. project-cloud.yml
  3. project-testing.yml
  4. project-defaults.yml

The same order of preference is applied even if you invoke the application as follows:

$ java -jar myapp-thorntail.jar -Scloud -Stesting -s/home/app/openshift.yml

Chapter 8. Packaging your application

This sections contains information about packaging your Thorntail–based application for deployment and execution.

8.1. Packaging Types

When using Thorntail, there are the following ways to package your runtime and application, depending on how you intend to use and deploy it:

8.1.1. Uberjar

An uberjar is a single Java .jar file that includes everything you need to execute your application. This means both the runtime components you have selected—​you can understand that as the app server—​along with the application components (your .war file).

An uberjar is useful for many continuous integration and continuous deployment (CI/CD) pipeline styles, in which a single executable binary artifact is produced and moved through the testing, validation, and production environments in your organization.

The names of the uberjars that Thorntail produces include the name of your application and the -thorntail.jar suffix.

An uberjar can be executed like any executable JAR:

$ java -jar myapp-thorntail.jar

8.1.2. Hollow JAR

A hollow JAR is similar to an uberjar, but includes only the runtime components, and does not include your application code.

A hollow jar is suitable for deployment processes that involve Linux containers such as Docker. When using containers, place the runtime components in a container image lower in the image hierarchy—​which means it changes less often—​so that the higher layer which contains only your application code can be rebuilt more quickly.

The names of the hollow JARs that Thorntail produces include the name of your application, and the -hollow-thorntail.jar suffix. You must package the .war file of your application separately in order to benefit from the hollow JAR.

Note

Using hollow JARs has certain limitations:

  • To enable Thorntail to autodetect a JDBC driver, you must add the JAR with the driver to the thorntail.classpath system property, for example:

    $ java -Dthorntail.classpath=./h2-1.4.196.jar -jar my-hollow-thorntail.jar myApp.war
  • YAML configuration files in your application are not automatically applied. You must specify them manually, for example:

    $ java -jar my-hollow-thorntail.jar myApp.war -s ./project-defaults.yml

When executing the hollow JAR, provide the application .war file as an argument to the Java binary:

$ java -jar myapp-hollow-thorntail.jar myapp.war

8.1.2.1. Pre-Built Hollow JARs

Thorntail ships the following pre-built hollow JARs:

web
Functionality focused on web technologies
microprofile
Functionality defined by all Eclipse MicroProfile specifications

The hollow JARs are available under the following coordinates:

<dependency>
    <groupId>io.thorntail.servers</groupId>
    <artifactId>[web|microprofile]</artifactId>
</dependency>

8.2. Creating an uberjar

One method of packaging an application for execution with Thorntail is as an uberjar.

Prerequisites

  • A Maven-based application with a pom.xml file.

Procedure

  1. Add the thorntail-maven-plugin to your pom.xml in a <plugin> block, with an <execution> specifying the package goal.

    <plugins>
      <plugin>
        <groupId>io.thorntail</groupId>
        <artifactId>thorntail-maven-plugin</artifactId>
        <version>${version.thorntail}</version>
        <executions>
          <execution>
            <id>package</id>
            <goals>
              <goal>package</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  2. Perform a normal Maven build:

    $ mvn package
  3. Execute the resulting uberjar:

    $ java -jar ./target/myapp-thorntail.jar

Chapter 9. Testing

9.1. Testing in a container

Using Arquillian, you have the capability of injecting unit tests into a running application. This allows you to verify your application is behaving correctly. There is an adapter for Thorntail that makes Arquillian-based testing work well with Thorntail–based applications.

Prerequisites

  • A Maven-based application with a pom.xml file.

Procedure

  1. Include the Thorntail BOM as described in Chapter 7, Using a BOM:

    <dependencyManagement>
      <dependencies>
        <dependency>
          <groupId>io.thorntail</groupId>
          <artifactId>bom</artifactId>
          <version>${version.thorntail}</version>
          <type>pom</type>
          <scope>import</scope>
        </dependency>
      </dependencies>
    </dependencyManagement>
  2. Reference the io.thorntail:arquillian artifact in your pom.xml file with the <scope> set to test:

    <dependencies>
      <dependency>
        <groupId>io.thorntail</groupId>
        <artifactId>arquillian</artifactId>
        <scope>test</scope>
      </dependency>
    </dependencies>
  3. Create your Application.

    Write your application as you normally would; use any default project-defaults.yml files you need to configure it.

    thorntail:
      datasources:
        data-sources:
          MyDS:
            driver-name: myh2
            connection-url: jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
            user-name: sa
            password: sa
        jdbc-drivers:
          myh2:
            driver-class-name: org.h2.Driver
            xa-datasource-name: org.h2.jdbcx.JdbcDataSource
            driver-module-name: com.h2database.h2
  4. Create a test class.

    Note

    Creating an Arquillian test before Thorntail existed usually involved programatically creating Archive due to the fact that applications were larger, and the aim was to test a single component in isolation.

    package org.wildfly.swarm.howto.incontainer;
    
    public class InContainerTest {
    }
  5. Create a deployment.

    In the context of microservices, the entire application represents one small microservice component.

    Use the @DefaultDeployment annotation to automatically create the deployment of the entire application. The @DefaultDeployment annotation defaults to creating a .war file, which is not applicable in this case because Undertow is not involved in this process.

    Apply the @DefaultDeployment annotation at the class level of a JUnit test, along with the @RunWith(Arquillian.class) annotation:

    @RunWith(Arquillian.class)
    @DefaultDeployment(type = DefaultDeployment.Type.JAR)
    public class InContainerTest {

    Using the @DefaultDeployment annotation provided by Arquillian integration with Thorntail means you should not use the Arquillian @Deployment annotation on static methods that return an Archive.

    The @DefaultDeployment annotation inspects the package of the test:

    package org.wildfly.swarm.howto.incontainer;

    From the package, it uses heuristics to include all of your other application classes in the same package or deeper in the Java packaging hierarchy.

    Even though using the @DefaultDeployment annotation allows you to write tests that only create a default deployment for sub-packages of your application, it also prevents you from placing tests in an unrelated package, for example:

    package org.mycorp.myapp.test;
  6. Write your test code.

    Write an Arquillian-type of test as you normally would, including using Arquillian facilities to gain access to internal running components.

    In the example below, Arquillian is used to inject the InitialContext of the running application into an instance member of the test case:

    @ArquillianResource
    InitialContext context;

    That means the test method itself can use that InitialContext to ensure the Datasource you configured using project-defaults.yml is live and available:

    @Test
    public void testDataSourceIsBound() throws Exception {
        DataSource ds = (DataSource) context.lookup("java:jboss/datasources/MyDS");
        assertNotNull( ds );
    }
  7. Run the tests.

    Because Arquillian provides an integration with JUnit, you can execute your test classes using Maven or your IDE:

    $ mvn install
    Note

    In many IDEs, execute a test class by right-clicking it and selecting Run.

Chapter 10. Debugging

This sections contains information about debugging your Thorntail–based application both in local and remote deployments.

10.1. Remote debugging

To remotely debug an application, you must first configure it to start in a debugging mode, and then attach a debugger to it.

10.1.1. Starting your application locally in debugging mode

One of the ways of debugging a Maven-based project is manually launching the application while specifying a debugging port, and subsequently connecting a remote debugger to that port. This method is applicable at least to the following deployments of the application:

  • When launching the application manually using the mvn thorntail:run goal.
  • When starting the application without waiting for it to exit using the mvn thorntail:start goal. This is useful especially when performing integration testing.
  • When using the Arquillian adapter for Thorntail.

Prerequisites

  • A Maven-based application

Procedure

  1. In a console, navigate to the directory with your application.
  2. Launch your application and specify the debug port using the -Dthorntail.debug.port argument:

    $ mvn thorntail:run -Dthorntail.debug.port=$PORT_NUMBER

    Here, $PORT_NUMBER is an unused port number of your choice. Remember this number for the remote debugger configuration.

10.1.2. Starting an uberjar in debugging mode

If you chose to package your application as a Thorntail uberjar, debug it by executing it with the following parameters.

Prerequisites

  • An uberjar with your application

Procedure

  1. In a console, navigate to the directory with the uberjar.
  2. Execute the uberjar with the following parameters. Ensure that all the parameters are specified before the name of the uberjar on the line.

    $ java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=$PORT_NUMBER -jar $UBERJAR_FILENAME

    $PORT_NUMBER is an unused port number of your choice. Remember this number for the remote debugger configuration.

    If you want the JVM to pause and wait for remote debugger connection before it starts the application, change suspend to y.

10.1.3. Starting your application on OpenShift in debugging mode

To debug your Thorntail-based application on OpenShift remotely, you must set the JAVA_DEBUG environment variable inside the container to true and configure port forwarding so that you can connect to your application from a remote debugger.

Prerequisites

  • Your application running on OpenShift.
  • The oc binary installed on your machine.
  • The ability to execute the oc port-forward command in your target OpenShift environment.

Procedure

  1. Using the oc command, list the available deployment configurations:

    $ oc get dc
  2. Set the JAVA_DEBUG environment variable in the deployment configuration of your application to true, which configures the JVM to open the port number 5005 for debugging. For example:

    $ oc set env dc/MY_APP_NAME JAVA_DEBUG=true
  3. Redeploy the application if it is not set to redeploy automatically on configuration change. For example:

    $ oc rollout latest dc/MY_APP_NAME
  4. Configure port forwarding from your local machine to the application pod:

    1. List the currently running pods and find one containing your application:

      $ oc get pod
      NAME                            READY     STATUS      RESTARTS   AGE
      MY_APP_NAME-3-1xrsp          0/1       Running     0          6s
      ...
    2. Configure port forwarding:

      $ oc port-forward MY_APP_NAME-3-1xrsp $LOCAL_PORT_NUMBER:5005

      Here, $LOCAL_PORT_NUMBER is an unused port number of your choice on your local machine. Remember this number for the remote debugger configuration.

  5. When you are done debugging, unset the JAVA_DEBUG environment variable in your application pod. For example:

    $ oc set env dc/MY_APP_NAME JAVA_DEBUG-

Additional resources

You can also set the JAVA_DEBUG_PORT environment variable if you want to change the debug port from the default, which is 5005.

10.1.4. Attaching a remote debugger to the application

When your application is configured for debugging, attach a remote debugger of your choice to it. In this guide, Red Hat CodeReady Studio is covered, but the procedure is similar when using other programs.

Prerequisites

  • The application running either locally or on OpenShift, and configured for debugging.
  • The port number that your application is listening on for debugging.
  • Red Hat CodeReady Studio installed on your machine. You can download it from the Red Hat CodeReady Studio download page.

Procedure

  1. Start Red Hat CodeReady Studio.
  2. Create a new debug configuration for your application:

    1. Click Run→Debug Configurations.
    2. In the list of configurations, double-click Remote Java application. This creates a new remote debugging configuration.
    3. Enter a suitable name for the configuration in the Name field.
    4. Enter the path to the directory with your application into the Project field. You can use the Browse…​ button for convenience.
    5. Set the Connection Type field to Standard (Socket Attach) if it is not already.
    6. Set the Port field to the port number that your application is listening on for debugging.
    7. Click Apply.
  3. Start debugging by clicking the Debug button in the Debug Configurations window.

    To quickly launch your debug configuration after the first time, click Run→Debug History and select the configuration from the list.

10.2. Debug logging

10.2.1. Local debug logging

To enable debug logging locally, see the Section 7.3.1, “Enabling logging” section and use the DEBUG log level.

If you want to enable debug logging permanently, add the following configuration to the src/main/resources/project-defaults.yml file in your application:

Debug logging YAML configuration

swarm:
  logging: DEBUG

10.2.2. Accessing debug logs on OpenShift

Start your application and interact with it to see the debugging statements in OpenShift.

Prerequisites

  • A Maven-based application with debug logging enabled.
  • The oc CLI client installed and authenticated.

Procedure

  1. Deploy your application to OpenShift:

    $ mvn clean fabric8:deploy -Popenshift
  2. View the logs:

    1. Get the name of the pod with your application:

      $ oc get pods
    2. Start watching the log output:

      $ oc logs -f pod/MY_APP_NAME-2-aaaaa

      Keep the terminal window displaying the log output open so that you can watch the log output.

  3. Interact with your application:

    For example, if you had debug logging in the REST API Level 0 example to log the message variable in the /api/greeting method:

    1. Get the route of your application:

      $ oc get routes
    2. Make an HTTP request on the /api/greeting endpoint of your application:

      $ curl $APPLICATION_ROUTE/api/greeting?name=Sarah
  4. Return to the window with your pod logs and inspect debug logging messages in the logs.

    ...
    2018-02-11 11:12:31,158 INFO  [io.openshift.MY_APP_NAME] (default task-18) Hello, Sarah!
    ...
  5. To disable debug logging, remove the logging key from the project-defaults.yml file and redeploy the appliation.

Chapter 11. Monitoring your application

This section contains information about monitoring your Thorntail–based application running on OpenShift.

11.1. Accessing JVM metrics for your application on OpenShift

11.1.1. Accessing JVM metrics using Jolokia on OpenShift

Jolokia is a built-in lightweight solution for accessing JMX (Java Management Extension) metrics over HTTP on OpenShift. Jolokia allows you to access CPU, storage, and memory usage data collected by JMX over an HTTP bridge. Jolokia uses a REST interface and JSON-formatted message payloads. It is suitable for monitoring cloud applications thanks to its comparably high speed and low resource requirements.

For Java-based applications, the OpenShift Web console provides the integrated hawt.io console that collects and displays all relevant metrics output by the JVM running your application.

Prerequistes

  • the oc client authenticated
  • a Java-based application container running in a project on OpenShift
  • latest JDK 1.8.0 image

Procedure

  1. List the deployment configurations of the pods inside your project and select the one that corresponds to your application.

    oc get dc
    NAME         REVISION   DESIRED   CURRENT   TRIGGERED BY
    MY_APP_NAME   2          1         1         config,image(my-app:6)
    ...
  2. Open the YAML deployment template of the pod running your application for editing.

    oc edit dc/MY_APP_NAME
  3. Add the following entry to the ports section of the template and save your changes:

    ...
    spec:
      ...
      ports:
      - containerPort: 8778
        name: jolokia
        protocol: TCP
      ...
    ...
  4. Redeploy the pod running your application.

    oc rollout latest dc/MY_APP_NAME

    The pod is redeployed with the updated deployment configuration and exposes the port 8778.

  5. Log into the OpenShift Web console.
  6. In the sidebar, navigate to Applications > Pods, and click on the name of the pod running your application.
  7. In the pod details screen, click Open Java Console to access the hawt.io console.

Appendix A. The Source-to-Image (S2I) build process

Source-to-Image (S2I) is a build tool for generating reproducible Docker-formatted container images from online SCM repositories with application sources. With S2I builds, you can easily deliver the latest version of your application into production with shorter build times, decreased resource and network usage, improved security, and a number of other advantages. OpenShift supports multiple build strategies and input sources.

For more information, see the Source-to-Image (S2I) Build chapter of the OpenShift Container Platform documentation.

You must provide three elements to the S2I process to assemble the final container image:

  • The application sources hosted in an online SCM repository, such as GitHub.
  • The S2I Builder image, which serves as the foundation for the assembled image and provides the ecosystem in which your application is running.
  • Optionally, you can also provide environment variables and parameters that are used by S2I scripts.

The process injects your application source and dependencies into the Builder image according to instructions specified in the S2I script, and generates a Docker-formatted container image that runs the assembled application. For more information, check the S2I build requirements, build options and how builds work sections of the OpenShift Container Platform documentation.

Appendix B. Updating the deployment configuration of an example application

The deployment configuration for an example application contains information related to deploying and running the application in OpenShift, such as route information or readiness probe location. The deployment configuration of an example application is stored in a set of YAML files. For examples that use the Fabric8 Maven Plugin, the YAML files are located in the src/main/fabric8/ directory. For examples using Nodeshift, the YAML files are located in the .nodeshift directory.

Important

The deployment configuration files used by the Fabric8 Maven Plugin and Nodeshift do not have to be full OpenShift resource definitions. Both Fabric8 Maven Plugin and Nodeshift can take the deployment configuration files and add some missing information to create a full OpenShift resource definition. The resource definitions generated by the Fabric8 Maven Plugin are available in the target/classes/META-INF/fabric8/ directory. The resource definitions generated by Nodeshift are available in the tmp/nodeshift/resource/ directory.

Prerequisites

  • An existing example project.
  • The oc CLI client installed.

Procedure

  1. Edit an existing YAML file or create an additional YAML file with your configuration update.

    • For example, if your example already has a YAML file with a readinessProbe configured, you could change the path value to a different available path to check for readiness:

      spec:
        template:
          spec:
            containers:
              readinessProbe:
                httpGet:
                  path: /path/to/probe
                  port: 8080
                  scheme: HTTP
      ...
    • If a readinessProbe is not configured in an existing YAML file, you can also create a new YAML file in the same directory with the readinessProbe configuration.
  2. Deploy the updated version of your example using Maven or npm.
  3. Verify that your configuration updates show in the deployed version of your example.

    $ oc export all --as-template='my-template'
    
    apiVersion: v1
    kind: Template
    metadata:
      creationTimestamp: null
      name: my-template
    objects:
    - apiVersion: v1
      kind: DeploymentConfig
      ...
      spec:
        ...
        template:
          ...
          spec:
            containers:
              ...
              livenessProbe:
                failureThreshold: 3
                httpGet:
                  path: /path/to/different/probe
                  port: 8080
                  scheme: HTTP
                initialDelaySeconds: 60
                periodSeconds: 30
                successThreshold: 1
                timeoutSeconds: 1
              ...

Additional resources

If you updated the configuration of your application directly using the web-based console or the oc CLI client, export and add these changes to your YAML file. Use the oc export all command to show the configuration of your deployed application.

Appendix C. Configuring a Jenkins freestyle project to deploy your application with the Fabric8 Maven Plugin

Similar to using Maven and the Fabric8 Maven Plugin from your local host to deploy an application, you can configure Jenkins to use Maven and the Fabric8 Maven Plugin to deploy an application.

Prerequisites

  • Access to an OpenShift cluster.
  • The Jenkins container image running on same OpenShift cluster.
  • A JDK and Maven installed and configured on your Jenkins server.
  • An application configured to use Maven, the Fabric8 Maven Plugin, and the Red Hat base image in the pom.xml.

    Note

    For building and deploying your applications to OpenShift, Spring Boot 2.1.x only supports builder images based on OpenJDK 8 and OpenJDK 11. Oracle JDK and OpenJDK 9 builder images are not supported.

    Example pom.xml

    <properties>
      ...
      <fabric8.generator.from>registry.access.redhat.com/redhat-openjdk-18/openjdk18-openshift:latest</fabric8.generator.from>
    </properties>

  • The source of the application available in GitHub.

Procedure

  1. Create a new OpenShift project for your application:

    1. Open the OpenShift Web console and log in.
    2. Click Create Project to create a new OpenShift project.
    3. Enter the project information and click Create.
  2. Ensure Jenkins has access to that project.

    For example, if you configured a service account for Jenkins, ensure that account has edit access to the project of your application.

  3. Create a new freestyle Jenkins project on your Jenkins server:

    1. Click New Item.
    2. Enter a name, choose Freestyle project, and click OK.
    3. Under Source Code Management, choose Git and add the GitHub url of your application.
    4. Under Build, choose Add build step and select Invoke top-level Maven targets.
    5. Add the following to Goals:

      clean fabric8:deploy -Popenshift -Dfabric8.namespace=MY_PROJECT

      Substitute MY_PROJECT with the name of the OpenShift project for your application.

    6. Click Save.
  4. Click Build Now from the main page of the Jenkins project to verify your application builds and deploys to the OpenShift project for your application.

    You can also verify that your application is deployed by opening the route in the OpenShift project of the application.

Next steps

  • Consider adding GITSCM polling or using the Poll SCM build trigger. These options enable builds to run every time a new commit is pushed to the GitHub repository.
  • Consider adding a build step that executes tests before deploying.

The maximum size of a batch to be inserted/deleted from the store. If the value is less than one, then no upper limit is placed on the number of operations in a batch.
thorntail.infinispan.cache-containers.KEY.distributed-caches.KEY.hotrod-store.passivation
If true, data is only written to the cache store when it is evicted from memory, a phenomenon known as 'passivation'. Next time the data is requested, it will be 'activated' which means that data will be brought back to memory and removed from the persistent store. If false, the cache store contains a copy of the contents in memory, so writes to cache result in cache store writes. This essentially gives you a 'write-through' configuration.
thorntail.infinispan.cache-containers.KEY.distributed-caches.KEY.hotrod-store.preload
If true, when the cache starts, data stored in the cache store will be pre-loaded into memory. This is particularly useful when data in the cache store will be needed immediately after startup and you want to avoid cache operations being delayed as a result of loading this data lazily. Can be used to provide a 'warm-cache' on startup, however there is a performance penalty as startup time is affected by this process.

thorntail.infinispan.cache-containers.KEY.invalidation-caches.KEY.binary-jdbc-store.passivation
If true, data is only written to the cache store when it is evicted from memory, a phenomenon known as 'passivation'. Next time the data is requested, it will be 'activated' which means that data will be brought back to memory and removed from the persistent store. If false, the cache store contains a copy of the contents in memory, so writes to cache result in cache store writes. This essentially gives you a 'write-through' configuration.
thorntail.infinispan.cache-containers.KEY.invalidation-caches.KEY.binary-jdbc-store.preload
If true, when the cache starts, data stored in the cache store will be pre-loaded into memory. This is particularly useful when data in the cache store will be needed immediately after startup and you want to avoid cache operations being delayed as a result of loading this data lazily. Can be used to provide a 'warm-cache' on startup, however there is a performance penalty as startup time is affected by this process.

thorntail.infinispan.cache-containers.KEY.local-caches.KEY.hotrod-store.max-batch-size
The maximum size of a batch to be inserted/deleted from the store. If the value is less than one, then no upper limit is placed on the number of operations in a batch.
thorntail.infinispan.cache-containers.KEY.local-caches.KEY.hotrod-store.passivation
If true, data is only written to the cache store when it is evicted from memory, a phenomenon known as 'passivation'. Next time the data is requested, it will be 'activated' which means that data will be brought back to memory and removed from the persistent store. If false, the cache store contains a copy of the contents in memory, so writes to cache result in cache store writes. This essentially gives you a 'write-through' configuration.
thorntail.infinispan.cache-containers.KEY.local-caches.KEY.hotrod-store.preload
If true, when the cache starts, data stored in the cache store will be pre-loaded into memory. This is particularly useful when data in the cache store will be needed immediately after startup and you want to avoid cache operations being delayed as a result of loading this data lazily. Can be used to provide a 'warm-cache' on startup, however there is a performance penalty as startup time is affected by this process.

The dialect of this datastore.
thorntail.infinispan.cache-containers.KEY.replicated-caches.KEY.binary-jdbc-store.fetch-state
If true, fetch persistent state when joining a cluster. If multiple cache stores are chained, only one of them can have this property enabled.
thorntail.infinispan.cache-containers.KEY.replicated-caches.KEY.binary-jdbc-store.max-batch-size
The maximum size of a batch to be inserted/deleted from the store. If the value is less than one, then no upper limit is placed on the number of operations in a batch.
thorntail.infinispan.cache-containers.KEY.replicated-caches.KEY.binary-jdbc-store.passivation
If true, data is only written to the cache store when it is evicted from memory, a phenomenon known as 'passivation'. Next time the data is requested, it will be 'activated' which means that data will be brought back to memory and removed from the persistent store. If false, the cache store contains a copy of the contents in memory, so writes to cache result in cache store writes. This essentially gives you a 'write-through' configuration.
thorntail.infinispan.cache-containers.KEY.replicated-caches.KEY.binary-jdbc-store.preload
If true, when the cache starts, data stored in the cache store will be pre-loaded into memory. This is particularly useful when data in the cache store will be needed immediately after startup and you want to avoid cache operations being delayed as a result of loading this data lazily. Can be used to provide a 'warm-cache' on startup, however there is a performance penalty as startup time is affected by this process.

thorntail.infinispan.cache-containers.KEY.replicated-caches.KEY.remote-store.preload
If true, when the cache starts, data stored in the cache store will be pre-loaded into memory. This is particularly useful when data in the cache store will be needed immediately after startup and you want to avoid cache operations being delayed as a result of loading this data lazily.
