Red Hat Process Automation Manager 7.8

Red Hat Customer Content Services

Abstract

This document describes how to deploy a Red Hat Process Automation Manager 7.8 authoring environment on Red Hat OpenShift Container Platform.

Preface

As a system engineer, you can deploy a Red Hat Process Automation Manager authoring environment on Red Hat OpenShift Container Platform to provide a platform for development of services, process applications, and other business assets.

Prerequisites

  • Red Hat OpenShift Container Platform version 3.11 is deployed.
  • At least four gigabytes of memory are available in the OpenShift cluster/namespace.
  • For a high-availability deployment, the following resources are available on the OpenShift cluster:

    • For the Business Central replicated pod, 8 gigabytes of memory and 2 CPU cores are required for each replica. Two replicas are created by default.
    • For the KIE Server replicated pod, 1 gigabyte of memory and 1 CPU core are required for each replica. Two replicas are created by default.
    • For the Red Hat Data Grid replicated pod, 2 gigabytes of memory and 1 CPU core are required for each replica. Two replicas are created by default.
    • The Red Hat AMQ replicated pod uses the default resource limits configured on your cluster.
    • The MySQL replicated pod uses the default resource limits configured on your cluster.
Note

For instructions about checking the capacity of your cluster, see Analyzing cluster capacity in the Red Hat OpenShift Container Platform 3.11 product documentation.

  • The OpenShift project for the deployment is created.
  • You are logged in to the project using the oc command. For more information about the oc command-line tool, see the OpenShift CLI Reference. If you want to use the OpenShift Web console to deploy templates, you must also be logged on using the Web console.
  • Dynamic persistent volume (PV) provisioning is enabled. Alternatively, if dynamic PV provisioning is not enabled, enough persistent volumes must be available. By default, the deployed components require the following PV sizes:

    • The replicated set of KIE Server pods requires one 1Gi PV for the database by default. You can change the database PV size in the template parameters. This requirement does not apply if you use an external database server.
    • Business Central requires one 1Gi PV by default. You can change the PV size for Business Central persistent storage in the template parameters.
  • If you intend to deploy a high-availability authoring environment, which includes high-availability Business Central, your OpenShift environment supports persistent volumes with ReadWriteMany mode. If your environment does not support this mode, you can use NFS to provision the volumes. However, for best performance and reliability, use GlusterFS to provision persistent volumes for a high-availability authoring environment. For information about access mode support in OpenShift public and dedicated clouds, see Access Modes.
Note

Since Red Hat Process Automation Manager version 7.5, images and templates for Red Hat OpenShift Container Platform 3.x are deprecated. These images and templates do not get new features, but remain supported until the end of full support for Red Hat OpenShift Container Platform version 3.x. For more information about the full support lifecycle phase for Red Hat OpenShift Container Platform version 3.x, see Red Hat OpenShift Container Platform Life Cycle Policy (non-current versions).

Note

Do not use Red Hat Process Automation Manager templates with Red Hat OpenShift Container Platform 4.x. To deploy Red Hat Process Automation Manager on Red Hat OpenShift Container Platform 4.x, see the instructions in Deploying a Red Hat Process Automation Manager environment on Red Hat OpenShift Container Platform using Operators.

Chapter 1. Overview of Red Hat Process Automation Manager on Red Hat OpenShift Container Platform

You can deploy Red Hat Process Automation Manager into a Red Hat OpenShift Container Platform environment.

In this solution, components of Red Hat Process Automation Manager are deployed as separate OpenShift pods. You can scale each of the pods up and down individually to provide as few or as many containers as required for a particular component. You can use standard OpenShift methods to manage the pods and balance the load.

The following key components of Red Hat Process Automation Manager are available on OpenShift:

  • KIE Server, also known as Execution Server, is the infrastructure element that runs decision services, process applications, and other deployable assets (collectively referred to as services) . All logic of the services runs on execution servers.

    A database server is normally required for KIE Server. You can provide a database server in another OpenShift pod or configure an execution server on OpenShift to use any other database server. Alternatively, KIE Server can use an H2 database; in this case, you cannot scale the pod.

    In some templates, you can scale up a KIE Server pod to provide as many copies as required, running on the same host or different hosts. As you scale a pod up or down, all of its copies use the same database server and run the same services. OpenShift provides load balancing and a request can be handled by any of the pods.

    You can deploy a separate KIE Server pod to run a different group of services. That pod can also be scaled up or down. You can have as many separate replicated KIE Server pods as required.

  • Business Central is a web-based interactive environment used for authoring services. It also provides a management and monitoring console. You can use Business Central to develop services and deploy them to KIE Servers. You can also use Business Central to monitor the execution of processes.

    Business Central is a centralized application. However, you can configure it for high availability, where multiple pods run and share the same data.

    Business Central includes a Git repository that holds the source for the services that you develop on it. It also includes a built-in Maven repository. Depending on configuration, Business Central can place the compiled services (KJAR files) into the built-in Maven repository or (if configured) into an external Maven repository.

  • Business Central Monitoring is a web-based management and monitoring console. It can manage the deployment of services to KIE Servers and provide monitoring information, but does not include authoring capabilities. You can use this component to manage staging and production environments.
  • Smart Router is an optional layer between KIE Servers and other components that interact with them. When your environment includes many services running on different KIE Servers, Smart Router provides a single endpoint to all client applications. A client application can make a REST API call that requires any service. Smart Router automatically calls the KIE Server that can process a particular request.

You can arrange these and other components into various environment configurations within OpenShift.

The following environment types are typical:

  • Authoring: An environment for creating and modifying services using Business Central. It consists of pods that provide Business Central for the authoring work and a KIE Server for test execution of the services. For instructions about deploying this environment, see Deploying a Red Hat Process Automation Manager authoring environment on Red Hat OpenShift Container Platform.
  • Managed deployment: An environment for running existing services for staging and production purposes. This environment includes several groups of KIE Server pods; you can deploy and undeploy services on every such group and also scale the group up or down as necessary. Use Business Central Monitoring to deploy, run, and stop the services and to monitor their execution.

    You can deploy two types of managed environment. In a freeform server environment, you initially deploy Business Central Monitoring and one KIE Server. You can additionally deploy any number of KIE Servers. Business Central Monitoring can connects to all servers in the same namespace. For instructions about deploying this environment, see Deploying a Red Hat Process Automation Manager freeform managed server environment on Red Hat OpenShift Container Platform.

    Alternatively, you can deploy a fixed managed server environment. A single deployment includes Business Central Monitoring, Smart Router, and a preset number of KIE Servers (by default, two servers, but you can modify the template to change the number). You cannot easily add or remove servers at a later time. For instructions about deploying this environment, see Deploying a Red Hat Process Automation Manager fixed managed server environment on Red Hat OpenShift Container Platform.

  • Deployment with immutable servers: An alternate environment for running existing services for staging and production purposes. In this environment, when you deploy a KIE Server pod, it builds an image that loads and starts a service or group of services. You cannot stop any service on the pod or add any new service to the pod. If you want to use another version of a service or modify the configuration in any other way, you deploy a new server image and displace the old one. In this system, the KIE Server runs like any other pod on the OpenShift environment; you can use any container-based integration workflows and do not need to use any other tools to manage the pods. Optionally, you can use Business Central Monitoring to monitor the performance of the environment and to stop and restart some of the service instances, but not to deploy additional services to any KIE Server or undeploy any existing ones (you cannot add or remove containers). For instructions about deploying this environment, see Deploying a Red Hat Process Automation Manager immutable server environment on Red Hat OpenShift Container Platform.

You can also deploy a trial or evaluation environment. This environment includes Business Central and a KIE Server. You can set it up quickly and use it to evaluate or demonstrate developing and running assets. However, the environment does not use any persistent storage, and any work you do in the environment is not saved. For instructions about deploying this environment, see Deploying a Red Hat Process Automation Manager trial environment on Red Hat OpenShift Container Platform.

To deploy a Red Hat Process Automation Manager environment on OpenShift, you can use the templates that are provided with Red Hat Process Automation Manager. You can modify the templates to ensure that the configuration suits your environment.

Chapter 2. Architecture of an authoring environment

In Red Hat Process Automation Manager, the Business Central component provides a web-based interactive user interface for authoring services. The KIE Server component runs the services.

The KIE Server uses a database server to store the state of process services.

You can also use Business Central to deploy services onto a KIE Server. You can use several KIE Servers to run different services and control the servers from the same Business Central.

Single authoring environment

In a single authoring environment, only one instance of Business Central is running. Multiple users can access its web interface at the same time, however the performance can be limited and there is no failover capability.

Business Central includes a built-in Maven repository that stores the built versions of the services that you develop (KJAR files/artifacts). You can use your continuous integration and continuous deployment (CICD) tools to retrieve these artifacts from the repository and move them as necessary.

Business Central saves the source code in a built-in Git repository, stored in the .niogit directory. It uses a built-in indexing mechanism to index the assets in your services.

Business Central uses persistent storage for the Maven repository and for the Git repository.

A single authoring environment, by default, includes one KIE Server. This KIE Server uses a built-in H2 database engine to store the state of process services.

A single authoring environment, by default, uses the controller strategy. Business Central includes the Controller, a component that can manage KIE Servers. When you configure a KIE Server to connect to Business Central, the KIE Server uses a REST API to connect to the Controller. This connection opens a persistent WebSocket. In an OpenShift deployment that uses the controller strategy, each KIE Server is initially configured to connect to the Business Central Controller.

When you use the Business Central user interface to deploy or manage a service on the KIE Server, the KIE Server receives the request through the Controller connection WebSocket. To deploy a service, the KIE Server requests the necessary artifact from the Maven repository that is a part of Business Central.

Client applications use a REST API to use services that run on the KIE Server.

Clustering KIE Servers and using multiple KIE Servers

You can scale a KIE Server pod to run a clustered KIE Server environment. To scale a KIE Server, you must ensure that it uses a database server in a separate pod or an external database server, and not a built-in H2 database engine.

In a clustered deployment, several instances of the KIE Server run the same services. These servers can connect to the Business Central Controller using the same server ID, so they can receive the same requests from the controller. Red Hat OpenShift Container Platform provides load-balancing between the servers. Decision services and business optimizer services that run on a clustered KIE Server must be stateless, because requests from the same client might be processed by different instances.

You can also deploy several independent KIE Servers to run different services. In this case, the servers connect to the Business Central Controller with different server ID values. You can use the Business Central UI to deploy services to each of the servers.

Smart Router

The optional Smart Router component provides a layer between client applications and KIE Servers. It can be useful if you are using several independent KIE Servers.

The client application can use services running on different KIE Servers, but always connects to the Smart Router. The Smart Router automatically passes the request to the KIE Servers that runs the required service. The Smart Router also enables management of service versions and provides an additional load-balancing layer.

High-availability authoring environment

In a high-availability (HA) authoring environment, the Business Central pod is scaled, so several instances of Business Central are running. Red Hat OpenShift Container Platform provides load balancing for user requests. This environment provides optimal performance for multiple users and supports failover.

Each instance of Business Central includes the Maven repository for the built artifacts and uses the .niogit Git repository for source code. The instances use shared persistent storage for the repositories. A persistent volume with ReadWriteMany access is required for this storage.

An instance of Red Hat DataGrid provides indexing of all projects and assets developed in Business Central.

An instance of Red Hat AMQ propagates Java CDI messages between all instances of Business Central. For example, when a new project is created or when an asset is locked or modified on one of the instances, this information is immediately reflected in all other instances.

The controller strategy is not suitable for clustered deployment. In an OpenShift deployment, a high-availability Business Central must manage KIE Servers using the OpenShift startup strategy.

Each KIE Server deployment (which can be scaled) creates a ConfigMap that reflects its current state. The Business Central discovers all KIE Servers by reading their ConfigMaps.

When the user requests a change in KIE Server configuration (for example, deploys or undeploys a service), Business Central initiates a connection to the KIE Server and sends a REST API request. The KIE Server changes the ConfigMap to reflect the new configuration state and then triggers its own redeployment, so that all instances are redeployed and reflect the new configuration.

You can deploy several independent KIE Servers in your OpenShift environment. Each of the KIE Servers has a separate ConfigMap with the necessary configuration. You can scale each of the KIE Servers separately.

You can include Smart Router in the OpenShift deployment.

Chapter 3. Preparing to deploy Red Hat Process Automation Manager in your OpenShift environment

Before deploying Red Hat Process Automation Manager in your OpenShift environment, you must complete several tasks. You do not need to repeat these tasks if you want to deploy additional images, for example, for new versions of processes or for other processes.

3.1. Ensuring the availability of image streams and the image registry

To deploy Red Hat Process Automation Manager components on Red Hat OpenShift Container Platform, you must ensure that OpenShift can download the correct images from the Red Hat registry. To download the images, OpenShift requires image streams, which contain the information about the location of images. OpenShift also must be configured to authenticate with the Red Hat registry using your service account user name and password.

Some versions of the OpenShift environment include the required image streams. You must check if they are available. If image streams are available in OpenShift by default, you can use them if the OpenShift infrastructure is configured for registry authentication server. The administrator must complete the registry authentication configuration when installing the OpenShift environment.

Otherwise, you can configure registry authentication in your own project and install the image streams in that project.

Procedure

  1. Determine whether Red Hat OpenShift Container Platform is configured with the user name and password for Red Hat registry access. For details about the required configuration, see Configuring a Registry Location. If you are using an OpenShift Online subscription, it is configured for Red Hat registry access.
  2. If Red Hat OpenShift Container Platform is configured with the user name and password for Red Hat registry access, enter the following commands:

    $ oc get imagestreamtag -n openshift | grep rhpam-businesscentral | grep 7.8
    $ oc get imagestreamtag -n openshift | grep rhpam-kieserver | grep 7.8

    If the outputs of both commands are not empty, the required image streams are available in the openshift namespace and no further action is required.

  3. If the output of one or both of the commands is empty or if OpenShift is not configured with the user name and password for Red Hat registry access, complete the following steps:

    1. Ensure you are logged in to OpenShift with the oc command and that your project is active.
    2. Complete the steps documented in Registry Service Accounts for Shared Environments. You must log in to the Red Hat Customer Portal to access the document and to complete the steps to create a registry service account.
    3. Select the OpenShift Secret tab and click the link under Download secret to download the YAML secret file.
    4. View the downloaded file and note the name that is listed in the name: entry.
    5. Enter the following commands:

      oc create -f <file_name>.yaml
      oc secrets link default <secret_name> --for=pull
      oc secrets link builder <secret_name> --for=pull

      Replace <file_name> with the name of the downloaded file and <secret_name> with the name that is listed in the name: entry of the file.

    6. Download the rhpam-7.8.0-openshift-templates.zip product deliverable file from the Software Downloads page and extract the rhpam78-image-streams.yaml file.
    7. Enter the following command:

      $ oc apply -f rhpam78-image-streams.yaml
      Note

      If you complete these steps, you install the image streams into the namespace of your project. In this case, when you deploy the templates, you must set the IMAGE_STREAM_NAMESPACE parameter to the name of this project.

3.2. Creating the secrets for KIE Server

OpenShift uses objects called secrets to hold sensitive information such as passwords or keystores. For more information about OpenShift secrets, see the Secrets chapter in the Red Hat OpenShift Container Platform documentation.

You must create an SSL certificate for HTTP access to KIE Server and provide it to your OpenShift environment as a secret.

Procedure

  1. Generate an SSL keystore with a private and public key for SSL encryption for KIE Server. For more information on how to create a keystore with self-signed or purchased SSL certificates, see Generate a SSL Encryption Key and Certificate.

    Note

    In a production environment, generate a valid signed certificate that matches the expected URL for KIE Server.

  2. Save the keystore in a file named keystore.jks.
  3. Record the name of the certificate. The default value for this name in Red Hat Process Automation Manager configuration is jboss.
  4. Record the password of the keystore file. The default value for this name in Red Hat Process Automation Manager configuration is mykeystorepass.
  5. Use the oc command to generate a secret named kieserver-app-secret from the new keystore file:

    $ oc create secret generic kieserver-app-secret --from-file=keystore.jks

3.3. Creating the secrets for Business Central

You must create an SSL certificate for HTTP access to Business Central and provide it to your OpenShift environment as a secret.

Do not use the same certificate and keystore for Business Central and KIE Server.

Procedure

  1. Generate an SSL keystore with a private and public key for SSL encryption for KIE Server. For more information on how to create a keystore with self-signed or purchased SSL certificates, see Generate a SSL Encryption Key and Certificate.

    Note

    In a production environment, generate a valid signed certificate that matches the expected URL for Business Central.

  2. Save the keystore in a file named keystore.jks.
  3. Record the name of the certificate. The default value for this name in Red Hat Process Automation Manager configuration is jboss.
  4. Record the password of the keystore file. The default value for this name in Red Hat Process Automation Manager configuration is mykeystorepass.
  5. Use the oc command to generate a secret named businesscentral-app-secret from the new keystore file:

    $ oc create secret generic businesscentral-app-secret --from-file=keystore.jks

3.4. Creating the secret for the administrative user

You must create a generic secret that contains the user name and password for a Red Hat Process Automation Manager administrative user account. This secret is required for deploying Red Hat Process Automation Manager using any template except the trial template.

The secret must contain the user name and password as literals. The key name for the user name is KIE_ADMIN_USER. The key name for the password is KIE_ADMIN_PWD.

If you are using multiple templates to deploy components of Red Hat Process Automation Manager, use the same secret for all these deployments. The components utilize this user account to communicate with each other.

You can also use this user account to log in to Business Central.

Important

If you use RH-SSO or LDAP authentication, the same user with the same password must be configured in your authentication system with the kie-server,rest-all,admin roles for Red Hat Process Automation Manager.

Procedure

Use the oc command to generate a generic secret named kie-admin-user-secret from the user name and password:

$ oc create secret generic rhpam-credentials --from-literal=KIE_ADMIN_USER=adminUser --from-literal=KIE_ADMIN_PWD=adminPassword

In this command, replace adminPassword with the password for the administrative user. Optionally, you can replace adminUser with another user name for the administrative user.

3.5. Changing GlusterFS configuration

You must check whether your OpenShift environment uses GlusterFS to provide permanent storage volumes. If it uses GlusterFS, to ensure optimal performance of Business Central, you must tune your GlusterFS storage by changing the storage class configuration.

Procedure

  1. To check whether your environment uses GlusterFS, enter the following command:

    oc get storageclass

    In the results, check whether the (default) marker is on the storage class that lists glusterfs. For example, in the following output the default storage class is gluster-container, which does list glusterfs:

    NAME              PROVISIONER                       AGE
    gluster-block     gluster.org/glusterblock          8d
    gluster-container (default) kubernetes.io/glusterfs 8d

    If the result has a default storage class that does not list glusterfs or if the result is empty, you do not need to make any changes. In this case, skip the rest of this procedure.

  2. To save the configuration of the default storage class into a YAML file, enter the following command:

    oc get storageclass <class-name> -o yaml >storage_config.yaml

    Replace <class-name> with the name of the default storage class. Example:

    oc get storageclass gluster-container -o yaml >storage_config.yaml
  3. Edit the storage_config.yaml file:

    1. Remove the lines with the following keys:

      • creationTimestamp
      • resourceVersion
      • selfLink
      • uid
    2. If you are planning to use Business Central only as a single pod, without high-availability configuration, on the line with the volumeoptions key, add the following options:

      features.cache-invalidation on
      performance.nl-cache on

      For example:

      volumeoptions: client.ssl off, server.ssl off, features.cache-invalidation on, performance.nl-cache on

    3. If you are planning to use Business Central in a high-availability configuration, on the line with the volumeoptions key, add the following options:

      features.cache-invalidation on
      nfs.trusted-write on
      nfs.trusted-sync on
      performance.nl-cache on
      performance.stat-prefetch off
      performance.read-ahead off
      performance.write-behind off
      performance.readdir-ahead off
      performance.io-cache off
      performance.quick-read off
      performance.open-behind off
      locks.mandatory-locking off
      performance.strict-o-direct on

      For example:

      volumeoptions: client.ssl off, server.ssl off, features.cache-invalidation on, nfs.trusted-write on, nfs.trusted-sync on, performance.nl-cache on, performance.stat-prefetch off, performance.read-ahead off, performance.write-behind off, performance.readdir-ahead off, performance.io-cache off, performance.quick-read off, performance.open-behind off, locks.mandatory-locking off, performance.strict-o-direct on

  4. To remove the existing default storage class, enter the following command:

    oc delete storageclass <class-name>

    Replace <class-name> with the name of the default storage class. Example:

    oc delete storageclass gluster-container
  5. To re-create the storage class using the new configuration, enter the following command:

    oc create -f storage_config.yaml

3.6. Provisioning persistent volumes with ReadWriteMany access mode using NFS

If you want to deploy high-availability Business Central or any KIE Servers that use the H2 database, which is the default setting for a non-high-availability authoring environment, your environment must provision persistent volumes with ReadWriteMany access mode.

Note

If you want to deploy a high-availability authoring environment, for optimal performance and reliability, provision persistent volumes using GlusterFS. Configure the GlusterFS storage class as described in Section 3.5, “Changing GlusterFS configuration”.

If your configuration requires provisioning persistent volumes with ReadWriteMany access mode but your environment does not support such provisioning, use NFS to provision the volumes. Otherwise, skip this procedure.

Procedure

Deploy an NFS server and provision the persistent volumes using NFS. For information about provisioning persistent volumes using NFS, see the "Persistent storage using NFS" section of the Configuring Clusters guide in the Red Hat OpenShift Container Platform 3.11 documentation.

3.7. Preparing a Maven mirror repository for offline use

If your Red Hat OpenShift Container Platform environment does not have outgoing access to the public Internet, you must prepare a Maven repository with a mirror of all the necessary artifacts and make this repository available to your environment.

Note

You do not need to complete this procedure if your Red Hat OpenShift Container Platform environment is connected to the Internet.

Prerequisites

  • A computer that has outgoing access to the public Internet is available.

Procedure

  1. Configure a Maven release repository to which you have write access. The repository must allow read access without authentication and your OpenShift environment must have network access to this repository.

    You can deploy a Nexus repository manager in the OpenShift environment. For instructions about setting up Nexus on OpenShift, see Setting up Nexus in the Red Hat OpenShift Container Platform 3.11 documentation. Use this repository as a separate mirror repository.

    Alternatively, if you use a custom external repository (for example, Nexus) for your services, you can use the same repository as a mirror repository.

  2. On the computer that has an outgoing connection to the public Internet, complete the following steps:

    1. Click Red Hat Process Automation Manager 7.8.0 Offliner Content List to download the rhpam-7.8.0-offliner.zip product deliverable file from the Software Downloads page of the Red Hat Customer Portal.
    2. Extract the contents of the rhpam-7.8.0-offliner.zip file into any directory.
    3. Change to the directory and enter the following command:

      ./offline-repo-builder.sh offliner.txt

      This command creates a repository subdirectory and downloads the necessary artifacts into this subdirectory.

      If a message reports that some downloads have failed, run the same command again. If downloads fail again, contact Red Hat support.

    4. Upload all artifacts from the repository subdirectory to the Maven mirror repository that you prepared. You can use the Maven Repository Provisioner utility, available from the Maven repository tools Git repository, to upload the artifacts.
  3. If you developed services outside Business Central and they have additional dependencies, add the dependencies to the mirror repository. If you developed the services as Maven projects, you can use the following steps to prepare these dependencies automatically. Complete the steps on the computer that has an outgoing connection to the public Internet.

    1. Create a backup of the local Maven cache directory (~/.m2/repository) and then clear the directory.
    2. Build the source of your projects using the mvn clean install command.
    3. For every project, enter the following command to ensure that Maven downloads all runtime dependencies for all the artifacts generated by the project:

      mvn -e -DskipTests dependency:go-offline -f /path/to/project/pom.xml --batch-mode -Djava.net.preferIPv4Stack=true

      Replace /path/to/project/pom.xml with the correct path to the pom.xml file of the project.

    4. Upload all artifacts from the local Maven cache directory (~/.m2/repository) to the Maven mirror repository that you prepared. You can use the Maven Repository Provisioner utility, available from the Maven repository tools Git repository, to upload the artifacts.

3.8. Building a custom KIE Server extension image for an external database

If you want to use an external database server for a KIE Server and the database server is not a MySQL or PostgreSQL server, you must build a custom KIE Server extension image with drivers for this server before deploying your environment.

Complete the steps in this build procedure to provide drivers for any of the following database servers:

  • Microsoft SQL Server
  • IBM DB2
  • Oracle Database
  • Sybase

Optionally, you can use this procedure to build a new version of drivers for any of the following database servers:

  • MySQL
  • MariaDB
  • PostgreSQL

For the supported versions of the database servers, see Red Hat Process Automation Manager 7 Supported Configurations.

The build procedure creates a custom extension image that extends the existing KIE Server image. You must import this custom extension image into your OpenShift environment and then reference it in the EXTENSION_IMAGE parameter.

Prerequisites

  • You are logged in to your OpenShift environment using the oc command. Your OpenShift user must have the registry-editor role.
  • For Oracle Database, IBM DB2, or Sybase, you downloaded the JDBC driver from the database server vendor.
  • You have installed the following required software:

    • Docker: For installation instructions, see Get Docker.
    • Cekit version 3.2: For installation instructions, see Installation.
    • The following libraries and extensions for Cekit. For more information, see Dependencies.

      • docker, provided by the python3-docker package or similar package
      • docker-squash, provided by the python3-docker-squash package or similar package
      • behave, provided by the python3-behave package or similar package

Procedure

  1. For IBM DB2, Oracle Database, or Sybase, provide the JDBC driver JAR file in a local directory.
  2. Download the rhpam-7.8.0-openshift-templates.zip product deliverable file from the Software Downloads page of the Red Hat Customer Portal.
  3. Unzip the file and, using the command line, change to the templates/contrib/jdbc/cekit directory of the unzipped file. This directory contains the source code for the custom build.
  4. Enter one of the following commands, depending on the database server type:

    • For Microsoft SQL Server:

      make mssql
    • For MySQL:

      make mysql
    • For PostgreSQL:

      make postgresql
    • For MariaDB:

      make mariadb
    • For IBM DB2:

      make db2 artifact=/tmp/db2jcc4.jar version=10.2

      In this command, replace /tmp/db2jcc4.jar with the path name of the downloaded Oracle Database driver and 10.2 with the version of the driver.

    • For Oracle Database:

      make oracle artifact=/tmp/ojdbc7.jar version=7.0

      In this command, replace /tmp/ojdbc7.jar with the path name of the downloaded Oracle Database driver and 7.0 with the version of the driver.

    • For Sybase:

      make build sybase artifact=/tmp/jconn4-16.0_PL05.jar version=16.0_PL05

      In this command, replace /tmp/jconn4-16.0_PL05.jar with the path name of the downloaded Sybase driver and 16.0_PL05 with the version of the driver.

      Alternatively, if you need to update the driver class or driver XA class for the Sybase driver, you can set the DRIVER_CLASS or DRIVER_XA_CLASS variable for this command, for example:

      export DRIVER_CLASS=another.class.Sybase && make sybase artifact=/tmp/jconn4-16.0_PL05.jar version=16.0_PL05
  5. Enter the following command to list the Docker images that are available locally:

    docker images

    Note the name of the image that was built, for example, jboss-kie-db2-extension-openshift-image, and the version tag of the image, for example, 11.1.4.4 (not the latest tag).

  6. Access the registry of your OpenShift environment directly and push the image to the registry. Depending on your user permissions, you can push the image into the openshift namespace or into a project namespace. For instructions about accessing the registry and pushing the images, see Accessing the Registry Directly in the Red Hat OpenShift Container Platform product documentation.
  7. When configuring your KIE Server deployment with a template that supports an external database server, set the following parameters:

    • Drivers Extension Image (EXTENSIONS_IMAGE): The ImageStreamTag definition of the extension image, for example, jboss-kie-db2-extension-openshift-image:11.1.4.4
    • Drivers ImageStream Namespace (EXTENSIONS_IMAGE_NAMESPACE): The namespace to which you uploaded the extension image, for example, openshift or your project namespace.

Chapter 4. Authoring environment

You can deploy an environment for creating and modifying processes using Business Central. It consists of Business Central for the authoring work and KIE Server for test execution of the processes. If necessary, you can connect additional KIE Servers to the Business Central.

Depending on your needs, you can deploy either a single authoring environment template or a high-availability (HA) authoring environment template.

A single authoring environment contains two pods. One of the pods runs Business Central, the other runs KIE Server. The KIE Server by default includes an embedded H2 database engine. This environment is most suitable for single-user authoring or when your OpenShift infrastructure has limited resources. It does not require persistent volumes that support the ReadWriteMany access mode.

In a single authoring environment, you cannot scale Business Central. By default, you also cannot scale KIE Server, as the H2 database engine does not support scaling. However, you can modify the template to use a separate MySQL or PostgreSQL database server pod; in this case, you can scale KIE Server. For instructions about modifying the single authoring environment template, see Section 4.6, “Modifying the template for the single authoring environment”.

In an HA authoring environment, both Business Central and KIE Server are provided in scalable pods. When pods are scaled, persistent storage is shared between the copies. The database is provided by a separate pod.

To enable high-availability functionality in Business Central, additional pods with AMQ and Data Grid are required. These pods are configured and deployed by the high-availability authoring template. Use a high-availability authoring environment to provide maximum reliability and responsiveness, especially if several users are involved in authoring at the same time.

In the current version of Red Hat Process Automation Manager, an HA authoring environment is supported with certain limitations:

  • If a Business Central pod crashes while a user works with it, the user can get an error message and then is redirected to another pod. Logging on again is not required.
  • If a Business Central pod crashes during a user operation, data that was not committed (saved) might be lost.
  • If a Business Central pod crashes during creation of a project, an unusable project might be created.
  • If a Business Central pod crashes during creation of an asset, the asset might be created but not indexed, so it cannot be used. The user can open the asset in Business Central and save it again to make it indexed.
  • When a user deploys a service to the KIE Server, the KIE Server deployment is rolled out again. Users can not deploy another service to the same KIE Server until the roll-out completes.

In a high-availability authoring environment you can also deploy additional managed or immutable KIE Servers, if required. Business Central can automatically discover any KIE Servers in the same namespace, including immutable KIE Servers and managed KIE Servers.

If you want to deploy additional managed or immutable KIE Servers in a single authoring environment, you must complete an additional manual step to enable the OpenShiftStartupStrategy setting in the environment, as described in Section 4.5, “Enabling the OpenShiftStartupStrategy setting to connect additional KIE Servers to Business Central”. This setting enables the discovery of other KIE Servers.

For instructions about deploying managed KIE Servers, see Deploying a Red Hat Process Automation Manager freeform managed server environment on Red Hat OpenShift Container Platform. For instructions about deploying immutable KIE Servers, see Deploying a Red Hat Process Automation Manager immutable server environment on Red Hat OpenShift Container Platform.

4.1. Deploying an authoring environment

You can use OpenShift templates to deploy a single or high-availability authoring environment. This environment consists of Business Central and a single KIE Server.

4.1.1. Starting configuration of the template for an authoring environment

If you want to deploy a single authoring environment, use the rhpam78-authoring.yaml template file. By default, the single authoring template uses the H2 database with permanent storage. If you prefer to create a MySQL or PostgreSQL pod or to use an external database server (outside the OpenShift project), modify the template before deploying the environment. For instructions about modifying the template, see Section 4.6, “Modifying the template for the single authoring environment”.

If you want to deploy a high-availability authoring environment, use the rhpam78-authoring-ha.yaml template file. By default, the high-availability authoring template creates a MySQL pod to provide the database server for the KIE Server. If you prefer to use PostgreSQL or to use an external server (outside the OpenShift project) you need to modify the template before deploying the environment. You can also modify the template to change the number of replicas initially created for Business Central. For instructions about modifying the template, see Section 4.7, “Modifying the template for the High Availability authoring environment”.

Procedure

  1. Download the rhpam-7.8.0-openshift-templates.zip product deliverable file from the Software Downloads page of the Red Hat Customer Portal.
  2. Extract the required template file.
  3. Use one of the following methods to start deploying the template:

    • To use the OpenShift Web UI, in the OpenShift application console select Add to Project → Import YAML / JSON and then select or paste the <template-file-name>.yaml file. In the Add Template window, ensure Process the template is selected and click Continue.
    • To use the OpenShift command line console, prepare the following command line:

      oc new-app -f <template-path>/<template-file-name>.yaml -p BUSINESS_CENTRAL_HTTPS_SECRET=businesscentral-app-secret -p KIE_SERVER_HTTPS_SECRET=kieserver-app-secret -p PARAMETER=value

      In this command line, make the following changes:

      • Replace <template-path> with the path to the downloaded template file.
      • Replace <template-file-name> with the name of the template file.
      • Use as many -p PARAMETER=value pairs as needed to set the required parameters.

Next steps

Set the parameters for the template. Follow the steps in Section 4.1.2, “Setting required parameters for an authoring environment” to set common parameters. You can view the template file to see descriptions for all parameters.

4.1.2. Setting required parameters for an authoring environment

When configuring the template to deploy an authoring environment, you must set the following parameters in all cases.

Prerequisites

Procedure

  1. Set the following parameters:

Next steps

If necessary, set additional parameters.

To complete the deployment, follow the procedure in Section 4.1.13, “Completing deployment of the template for an authoring environment”.

4.1.3. Configuring the image stream namespace for an authoring environment

If you created image streams in a namespace that is not openshift, you must configure the namespace in the template.

If all image streams were already available in your Red Hat OpenShift Container Platform environment, you can skip this procedure.

Prerequisites

Procedure

If you installed an image streams file according to instructions in Section 3.1, “Ensuring the availability of image streams and the image registry”, set the ImageStream Namespace (IMAGE_STREAM_NAMESPACE) parameter to the name of your OpenShift project.

4.1.4. Setting an optional Maven repository for an authoring environment

When configuring the template to deploy an authoring environment, if you want to place the built KJAR files into an external Maven repository, you must set parameters to access the repository.

Prerequisites

Procedure

To configure access to a custom Maven repository, set the following parameters:

  • Maven repository URL (MAVEN_REPO_URL): The URL for the Maven repository.
  • Maven repository ID (MAVEN_REPO_ID): An identifier for the Maven repository. The default value is repo-custom.
  • Maven repository username (MAVEN_REPO_USERNAME): The user name for the Maven repository.
  • Maven repository password (MAVEN_REPO_PASSWORD): The password for the Maven repository.

Next steps

If necessary, set additional parameters.

To complete the deployment, follow the procedure in Section 4.1.13, “Completing deployment of the template for an authoring environment”.

Important

To export or push Business Central projects as KJAR artifacts to the external Maven repository, you must also add the repository information in the pom.xml file for every project. For information about exporting Business Central projects to an external repository, see Packaging and deploying a Red Hat Process Automation Manager project.

4.1.5. Configuring access to a Maven mirror in an environment without a connection to the public Internet for an authoring environment

When configuring the template to deploy an authoring environment, if your OpenShift environment does not have a connection to the public Internet, you must configure access to a Maven mirror that you set up according to Section 3.7, “Preparing a Maven mirror repository for offline use”.

Prerequisites

Procedure

To configure access to the Maven mirror, set the following parameters:

  • Maven mirror URL (MAVEN_MIRROR_URL): The URL for the Maven mirror repository that you set up in Section 3.7, “Preparing a Maven mirror repository for offline use”. This URL must be accessible from a pod in your OpenShift environment.
  • Maven mirror of (MAVEN_MIRROR_OF): The value that determines which artifacts are to be retrieved from the mirror. For instructions about setting the mirrorOf value, see Mirror Settings in the Apache Maven documentation. The default value is external:*,!repo-rhpamcentr; with this value, Maven retrieves artifacts from the built-in Maven repository of Business Central directly and retrieves any other required artifacts from the mirror. If you configure an external Maven repository (MAVEN_REPO_URL), change MAVEN_MIRROR_OF to exclude the artifacts in this repository, for example, external:*,!repo-custom. Replace repo-custom with the ID that you configured in MAVEN_REPO_ID.

Next steps

If necessary, set additional parameters.

To complete the deployment, follow the procedure in Section 4.1.13, “Completing deployment of the template for an authoring environment”.

4.1.6. Configuring Business Central and KIE Server replicas for a high-availability authoring environment

If you are deploying a high-availability authoring environment, by default two replicas of Business Central and two replicas of the KIE Server are initially created.

Optionally, you can modify the number of replicas.

Skip this procedure for a single authoring environment.

Prerequisites

Procedure

To modify the numbers of initial replicas, set the following parameters:

  • Business Central Container Replicas (BUSINESS_CENTRAL_CONTAINER_REPLICAS): The number of replicas that the deployment initially creates for Business Central.
  • KIE Server Container Replicas (KIE_SERVER_CONTAINER_REPLICAS): The number of replicas that the deployment initially creates for the KIE Server.

Next steps

If necessary, set additional parameters.

To complete the deployment, follow the procedure in Section 4.1.13, “Completing deployment of the template for an authoring environment”.

4.1.7. Specifying the Git hooks directory for an authoring environment

You can use Git hooks to facilitate interaction between the internal Git repository of Business Central and an external Git repository.

If you want to use Git hooks, you must configure a Git hooks directory.

Prerequisites

Procedure

To configure a Git hooks directory, set the following parameter:

  • Git hooks directory (GIT_HOOKS_DIR): The fully qualified path to a Git hooks directory, for example, /opt/kie/data/git/hooks. You must provide the content of this directory and mount it at the specified path. For instructions about providing and mounting the Git hooks directory using a configuration map or a persistent volume, see Section 4.2, “(Optional) Providing the Git hooks directory”.

Next steps

If necessary, set additional parameters.

To complete the deployment, follow the procedure in Section 4.1.13, “Completing deployment of the template for an authoring environment”.

4.1.8. Configuring resource usage for a high-availability deployment

If you are deploying the high-availability template (rhpam78-authoring-ha.yaml), you can optionally configure resource usage to optimize performance for your requirements.

If you are deploying the single authoring environment template (rhpam78-authoring.yaml), skip this procedure.

For more information about sizing resources, see the following sections in the Red Hat OpenShift Container Platform 3.11 product documentation:

Prerequisites

Procedure

Set the following parameters of the template as applicable:

  • Business Central Container Memory Limit (BUSINESS_CENTRAL_MEMORY_LIMIT): The amount of memory requested in the OpenShift environment for the Business Central container. The default value is 8Gi.
  • Business Central JVM Max Memory Ratio (BUSINESS_CENTRAL_JAVA_MAX_MEM_RATIO): The percentage of container memory that is used for the Java Virtual Machine for Business Central. The remaining memory is used for the operating system. The default value is 80, for a limit of 80%.

      • KIE Server RH-SSO Client name (KIE_SERVER_SSO_CLIENT): The name of the client to create in RH-SSO for KIE Server.
      • KIE Server RH-SSO Client Secret (KIE_SERVER_SSO_SECRET): The secret string to set in RH-SSO for the client for KIE Server.
      • RH-SSO Realm Admin Username (SSO_USERNAME) and RH-SSO Realm Admin Password (SSO_PASSWORD): The user name and password for the realm administrator user for the RH-SSO realm for Red Hat Process Automation Manager. You must provide this user name and password in order to create the required clients.

Next steps

If necessary, set additional parameters.

To complete the deployment, follow the procedure in Section 4.1.13, “Completing deployment of the template for an authoring environment”.

After completing the deployment, review the URLs for components of Red Hat Process Automation Manager in the RH-SSO authentication system to ensure they are correct.

4.1.10. Setting parameters for LDAP authentication for an authoring environment

If you want to use LDAP authentication, complete the following additional configuration when configuring the template to deploy an authoring environment.

Important

Do not configure LDAP authentication and RH-SSO authentication in the same deployment.

Prerequisites

Procedure

  1. Set the AUTH_LDAP* parameters of the template. These parameters correspond to the settings of the LdapExtended Login module of Red Hat JBoss EAP. For instructions about using these settings, see LdapExtended login module.

    If the LDAP server does not define all the roles required for your deployment, you can map LDAP groups to Red Hat Process Automation Manager roles. To enable LDAP role mapping, set the following parameters:

    • RoleMapping rolesProperties file path (AUTH_ROLE_MAPPER_ROLES_PROPERTIES): The fully qualified path name of a file that defines role mapping, for example, /opt/eap/standalone/configuration/rolemapping/rolemapping.properties. You must provide this file and mount it at this path in all applicable deployment configurations; for instructions, see Section 4.4, “(Optional) Providing the LDAP role mapping file”.
    • RoleMapping replaceRole property (AUTH_ROLE_MAPPER_REPLACE_ROLE): If set to true, mapped roles replace the roles defined on the LDAP server; if set to false, both mapped roles and roles defined on the LDAP server are set as user application roles. The default setting is false.

Next steps

If necessary, set additional parameters.

To complete the deployment, follow the procedure in Section 4.1.13, “Completing deployment of the template for an authoring environment”.

4.1.11. Setting parameters for using an external database server for an authoring environment

      • org.hibernate.dialect.DB2Dialect
      • org.hibernate.dialect.Oracle10gDialect
      • org.hibernate.dialect.SybaseASE15Dialect

        For a complete list of supported dialects, see Table A.7 in Hibernate properties in the Red Hat JBoss EAP documentation.

    • KIE Server External Database name (KIE_SERVER_EXTERNALDB_DB): The database name to use on the external database server
    • JDBC Connection Checker class (KIE_SERVER_EXTERNALDB_CONNECTION_CHECKER): The name of the JDBC connection checker class for the database server. Without this information, a database server connection cannot be restored after it is lost, for example, if the database server is rebooted.
    • JDBC Exception Sorter class (KIE_SERVER_EXTERNALDB_EXCEPTION_SORTER): The name of the JDBC exception sorter class for the database server. Without this information, a database server connection cannot be restored after it is lost, for example, if the database server is rebooted.
  2. If you created a custom image for using an external database server, as described in Section 3.8, “Building a custom KIE Server extension image for an external database”, set the following parameters:

    • Drivers Extension Image (EXTENSIONS_IMAGE): The ImageStreamTag definition of the extension image, for example, jboss-kie-db2-extension-openshift-image:11.1.4.4
    • Drivers ImageStream Namespace (EXTENSIONS_IMAGE_NAMESPACE): The namespace to which you uploaded the extension image, for example, openshift or your project namespace.
  3. If you are using a MySQL version 8 external database server, enable the mysql_native_password plugin and use it for authentication. For instructions about this pluding, see Native Pluggable Authentication in the MySQL 8.0 Reference Manual.

    If you are using a MySQL version 8 image provided by Red Hat on Red Hat OpenShift Container Platform, to enable the plugin, set the MYSQL_DEFAULT_AUTHENTICATION_PLUGIN environment variable to mysql_native_password.

    If you created users on the MySQL version 8 server before enabling the mysql_native_password plugin, you must update the mysql-user table after you enable the plugin.

Next steps

If necessary, set additional parameters.

To complete the deployment, follow the procedure in Section 4.1.13, “Completing deployment of the template for an authoring environment”.

4.1.12. Enabling Prometheus metric collection for an authoring environment

If you want to configure your KIE Server deployment to use Prometheus to collect and store metrics, enable support for this feature in KIE Server at deployment time.

Prerequisites

Procedure

To enable support for Prometheus metric collection, set the Prometheus Server Extension Disabled (PROMETHEUS_SERVER_EXT_DISABLED) parameter to false.

Next steps

If necessary, set additional parameters.

To complete the deployment, follow the procedure in Section 4.1.13, “Completing deployment of the template for an authoring environment”.

For instructions about configuring Prometheus metrics collection, see Managing and monitoring KIE Server.

4.1.13. Completing deployment of the template for an authoring environment

After setting all the required parameters in the OpenShift Web UI or in the command line, complete deployment of the template.

Procedure

Depending on the method that you are using, complete the following steps:

  • In the OpenShift Web UI, click Create.

    • If the This will create resources that may have security or project behavior implications message appears, click Create Anyway.
  • Complete the command line and press Enter.

4.2. (Optional) Providing the Git hooks directory

If you configure the GIT_HOOKS_DIR parameter, you must provide a directory of Git hooks and must mount this directory on the Business Central deployment.

The typical use of Git hooks is interaction with an upstream repository. To enable Git hooks to push commits into an upstream repository, you must also provide a secret key that corresponds to a public key configured on the upstream repository.

Procedure

  1. If interaction with an upstream repository using SSH authentication is required, complete the following steps to prepare and mount a secret with the necessary files:

    1. Prepare the id_rsa file with a private key that matches a public key stored in the repository.
    2. Prepare the known_hosts file with the correct name, address, and public key for the repository.
    3. Create a secret with the two files using the oc command, for example:

      oc create secret git-hooks-secret --from-file=id_rsa=id_rsa --from-file=known_hosts=known_hosts
    4. Mount the secret in the SSH key path of the Business Central deployment, for example:

      oc set volume dc/<myapp>-rhpamcentr --add --type secret --secret-name git-hooks-secret --mount-path=/home/jboss/.ssh --name=ssh-key

      Replace <myapp> with the application name that you set when configuring the template.

  2. Create the Git hooks directory. For instructions, see the Git hooks reference documentation.

    For example, a simple Git hooks directory can provide a post-commit hook that pushes the changes upstream. If the project was imported into Business Central from a repository, this repository remains configured as the upstream repository. Create a file named post-commit with permission values 755 and the following content:

    git push
    Note

    A pre-commit script is not supported in Business Central. Use a post-commit script.

  3. Supply the Git hooks directory to the Business Central deployment. You can use a configuration map or a persistent volume.

    1. If the Git hooks consist of one or several fixed script files, use a configuration map. Complete the following steps:

      1. Change into the Git hooks directory that you have created.
      2. Create an OpenShift configuration map from the files in the directory. Run the following command:

        oc create configmap git-hooks --from-file=<file_1>=<file_1> --from-file=<file_2>=<file_2> ...

        Replace file_1, file_2, and so on with Git hook script file names. Example:

        oc create configmap git-hooks --from-file=post-commit=post-commit
      3. Mount the configuration map on the Business Central deployment in the path that you have configured:

        oc set volume dc/<myapp>-rhpamcentr --add --type configmap --configmap-name git-hooks  --mount-path=<git_hooks_dir> --name=git-hooks

        Replace <myapp> with the application name that was set when configuring the template and <git_hooks_dir> is the value of GIT_HOOKS_DIR that was set when configuring the template.

    2. If the Git hooks consist of long files or depend on binaries, such as executable or KJAR files, use a persistence volume. You must create a persistent volume, create a persistent volume claim and associate the volume with the claim, transfer files to the volume, and mount the volume in the myapp-rhpamcentr deployment configuration (replace myapp with the application name). For instructions about creating and mounting persistence volumes, see Using persistent volumes. For instructions about copying files onto a persistent volume, see Transferring files in and out of containers.
  4. Wait a few minutes, then review the list and status of pods in your project. Because Business Central does not start until you provide the Git hooks directory, the KIE Server might not start at all. To see if it has started, check the output of the following command:

    oc get pods

    If a working KIE Server pod is not present, start it:

    oc rollout latest dc/<myapp>-kieserver

    Replace <myapp> with the application name that was set when configuring the template.

4.3. (Optional) Providing a truststore for accessing HTTPS servers with self-signed certificates

Components of your Red Hat Process Automation Manager infrastructure might need to use HTTPS access to servers that have a self-signed HTTPS certificate. For example, Business Central and KIE Server might need to interact with an internal Nexus repository that uses a self-signed HTTPS server certificate.

In this case, to ensure that HTTPS connections complete successfully, you must provide client certificates for these services using a truststore.

Skip this procedure if you do not need Red Hat Process Automation Manager components to communicate with servers that use self-signed HTTPS server certificates.

Procedure

  1. Prepare a truststore with the certificates. Use the following command to create a truststore or to add a certificate to an existing truststore. Add all the necessary certificates to one truststore.

    keytool -importcert -file certificate-file -alias alias -keyalg algorithm -keysize size -trustcacerts -noprompt -storetype JKS -keypass truststore-password -storepass truststore-password -keystore keystore-file

    Replace the following values:

    • certificate-file: The pathname of the certificate that you want to add to the truststore.
    • alias: The alias for the certificate in the truststore. If you are adding more than one certificate to the truststore, every certificate must have a unique alias.
    • algorithm: The encryption algorithm used for the certificate, typically RSA.
    • size: The size of the certificate key in bytes, for example, 2048.
    • truststore-password: The password for the truststore.
    • keystore-file: The pathname of the truststore file. If the file does not exist, the command creates a new truststore.

      The following example command adds a certificate from the /var/certs/nexus.cer file to a truststore in the /var/keystores/custom-trustore.jks file. The truststore password is mykeystorepass.

      keytool -importcert -file /var/certs/nexus.cer -alias nexus-cert -keyalg RSA -keysize 2048 -trustcacerts -noprompt -storetype JKS -keypass mykeystorepass -storepass mykeystorepass -keystore /var/keystores/custom-trustore.jks
  2. Create a secret with the truststore file using the oc command, for example:

    oc create secret generic truststore-secret --from-file=/var/keystores/custom-trustore.jks
  3. In the deployment for the necessary components of your infrastructure, mount the secret and then set the JAVA_OPTS_APPEND option to enable the Java application infrastructure to use the trast store, for example:

    oc set volume dc/myapp-rhpamcentr --add --overwrite --name=custom-trustore-volume --mount-path /etc/custom-secret-volume --secret-name=custom-secret
    
    oc set env dc/myapp-rhpamcentr JAVA_OPTS_APPEND='-Djavax.net.ssl.trustStore=/etc/custom-secret-volume/custom-trustore.jks -Djavax.net.ssl.trustStoreType=jks -Djavax.net.ssl.trustStorePassword=mykeystorepass'
    oc set volume dc/myapp-kieserver --add --overwrite --name=custom-trustore-volume --mount-path /etc/custom-secret-volume --secret-name=custom-secret
    
    oc set env dc/myapp-kieserver JAVA_OPTS_APPEND='-Djavax.net.ssl.trustStore=/etc/custom-secret-volume/custom-trustore.jks -Djavax.net.ssl.trustStoreType=jks -Djavax.net.ssl.trustStorePassword=mykeystorepass'

    Replace myapp with the application name that you set when configuring the template.

4.4. (Optional) Providing the LDAP role mapping file

If you configure the AUTH_ROLE_MAPPER_ROLES_PROPERTIES parameter, you must provide a file that defines the role mapping. Mount this file on all affected deployment configurations.

Procedure

  1. Create the role mapping properties file, for example, my-role-map. The file must contain entries in the following format:

    ldap_role = product_role1, product_role2...

    For example:

    admins = kie-server,rest-all,admin
  2. Create an OpenShift configuration map from the file by entering the following command:

    oc create configmap ldap-role-mapping --from-file=<new_name>=<existing_name>

    Replace <new_name> with the name that the file is to have on the pods (it must be the same as the name specified in the AUTH_ROLE_MAPPER_ROLES_PROPERTIES file) and <existing_name> with the name of the file that you created. Example:

    oc create configmap ldap-role-mapping --from-file=rolemapping.properties=my-role-map
  3. Mount the configuration map on every deployment configuration that is configured for role mapping.

    The following deployment configurations can be affected in this environment:

    • myapp-rhpamcentr: Business Central
    • myapp-kieserver: KIE Server

    Replace myapp with the application name. Sometimes, several KIE Server deployments can be present under different application names.

    For every deployment configuration, run the command:

     oc set volume dc/<deployment_config_name> --add --type configmap --configmap-name ldap-role-mapping --mount-path=<mapping_dir> --name=ldap-role-mapping

    Replace <mapping_dir> with the directory name (without file name) set in the AUTH_ROLE_MAPPER_ROLES_PROPERTIES parameter, for example, /opt/eap/standalone/configuration/rolemapping .

4.5. Enabling the OpenShiftStartupStrategy setting to connect additional KIE Servers to Business Central

In an environment deployed using Red Hat Process Automation Manager authoring templates, Business Central manages one KIE Server. If you use the high-avalability authoring template or if you modified the single authoring template to use a database server other than an embedded H2 database, you can scale the KIE Server pod, but all the copies execute the same services.

You can connect additional KIE Servers to Business Central. However, if you deployed a single authoring environment using the rhpam78-authoring.yaml, you must enable the OpenShiftStartupStrategy setting in the environment. When OpenShiftStartupStrategy is enabled, Business Central automatically discovers KIE Servers in the same namespace and these KIE Servers can be configured to connect to the Business Central.

With the OpenShiftStartupStrategy setting, when a user deploys a service to the KIE Server, the KIE Server deployment is rolled out again. Users can not deploy another service to the same KIE Server until the roll-out completes. Because the roll-out might take noticeable time, the OpenShiftStartupStrategy setting might not be suitable for some authoring environments.

Do not complete this procedure if you deployed a high-availability authoring environment using the rhpam78-authoring-ha.yaml template. In this environment, the OpenShiftStartupStrategy setting is enabled by default.

Do not complete this procedure unless you want to connect additional KIE Servers to Business Central.

Prerequisites

  • You deployed an authoring environment using the rhpam78-authoring.yaml template.
  • You are logged in to the OpenShift project where the environment is deployed using the oc tool.

Procedure

  1. Enter the following command to view the deployment configurations that are deployed in the project:

    $ oc get dc
  2. In the output of the command, find the deployment configuration names for the Business Central and KIE Server pods:

    • The name of the deployment configuration for Business Central is myapp-rhpamcentr. Replace myapp with the application name of the environment, which is set in the APPLICATION_NAME parameter of the template.
    • The name of the deployment configuration for KIE Server is myapp-kieserver. Replace myapp with the application name.
  3. Enter the following commands to enable the OpenShiftStartupStrategy setting on the pods:

    $ oc env myapp-rhpamcentr KIE_SERVER_CONTROLLER_OPENSHIFT_ENABLED=true
    $ oc env myapp-kieserver KIE_SERVER_STARTUP_STRATEGY=OpenShiftStartupStrategy

    In these commands, replace myapp-rhpamcentr with the Business Central deployment configuration name and myapp-kieserver with the KIE Server deployment configuration name.

  4. When you enable the OpenShiftStartupStrategy setting, by default Business Central discovers only KIE Servers that are deployed with the same value of the APPLICATION_NAME parameter as the authoring template. If you want to connect KIE Servers with any other application names to the Business Central, enter the following command:

    $ oc env myapp-rhpamcentr KIE_SERVER_CONTROLLER_OPENSHIFT_GLOBAL_DISCOVERY_ENABLED=true

    In this command, replace myapp-rhpamcentr with the Business Central deployment configuration name.

4.6. Modifying the template for the single authoring environment

By default, the single authoring template uses the H2 database with permanent storage. If you prefer to create a MySQL or PostgreSQL pod or to use an external database server (outside the OpenShift project), modify the template before deploying the environment.

You must use a MySQL or PostgreSQL pod or an external database server if you want to scale the KIE Server pod. An OpenShift template defines a set of objects that can be created by OpenShift. To change an environment configuration, you need to modify, add, or delete these objects. To simplify this task, comments are provided in the Red Hat Process Automation Manager templates.

Some comments mark blocks within the template, staring with BEGIN and ending with END. For example, the following block is named Sample block:

## Sample block BEGIN
sample line 1
sample line 2
sample line 3
## Sample block END

For some changes, you might need to replace a block in one template file with a block from another template file provided with Red Hat Process Automation Manager. In this case, delete the block, then paste the new block in its exact location.

Procedure

Edit the rhpam78-authoring.yaml template file to make any of the following changes as necessary.

  • If you want to use MySQL instead of the H2 database, you need to replace several blocks of the file, marked with comments from BEGIN to END, with blocks from the rhpam78-kieserver-mysql.yaml file that are also marked with comments. You also need to remove several other blocks and to add blocks in designated locations:

    1. Replace the block named H2 database parameters with the block named MySQL database parameters. (Take this block and all subsequent replacement blocks from the rhpam78-kieserver-mysql.yaml file.)
    2. Replace the block named H2 driver settings with the block named MySQL driver settings.
    3. Replace the block named H2 persistent volume claim with the block named MySQL persistent volume claim.
    4. Remove the blocks named H2 volume mount and H2 volume settings.
    5. Under the comment Place to add database service, add the block named MySQL service.
    6. Under the comment Place to add database deployment config, add the block named MySQL deployment config.
  • If you want to use PostgreSQL instead of the H2 database, you need to replace several blocks of the file, marked with comments from BEGIN to END, with blocks from the rhpam78-kieserver-postgresql.yaml file that are also marked with comments. You also need to remove several other blocks and to add blocks in designated locations:

    1. Replace the block named H2 database parameters with the block named PostgreSQL database parameters. (Take this block and all subsequent replacement blocks from the rhpam78-kieserver-postgresql.yaml file.)
    2. Replace the block named H2 driver settings with the block named PostgreSQL driver settings.
    3. Replace the block named H2 persistent volume claim with the block named PostgreSQL persistent volume claim.
    4. Remove the blocks named H2 volume mount and H2 volume settings.
    5. Under the comment Place to add database service, add the block named PostgreSQL service.
    6. Under the comment Place to add database deployment config, add the block named PostgreSQL deployment config.
  • If you want to use an external database server, replace several blocks of the file, marked with comments from BEGIN to END, with blocks from the rhpam78-kieserver-externaldb.yaml file, and also remove some blocks:

    1. Replace the block named H2 database parameters with the block named External database parameters. (Take this block and all subsequent replacement blocks from the rhpam78-kieserver-externaldb.yaml file.)
    2. Replace the block named H2 driver settings with the block named External database driver settings.
    3. Remove the following blocks of the file, marked with comments from BEGIN to END:

      • H2 persistent volume claim
      • H2 volume mount
      • H2 volume settings
Important

The standard KIE Server image includes drivers for MySQL, MariaDB, and PostgreSQL external database servers. If you want to use another database server, you must build a custom KIE Server image. For instructions, see Section 3.8, “Building a custom KIE Server extension image for an external database”.

4.7. Modifying the template for the High Availability authoring environment

By default, the high-availability authoring template creates a MySQL pod to provide the database server for the KIE Server. If you prefer to use PostgreSQL or to use an external server (outside the OpenShift project), you need to modify the template before deploying the environment.

You can also modify the High Availability authoring template to change the number of replicas initially created for Business Central.

An OpenShift template defines a set of objects that can be created by OpenShift. To change an environment configuration, you need to modify, add, or delete these objects. To simplify this task, comments are provided in the Red Hat Process Automation Manager templates.

Some comments mark blocks within the template, staring with BEGIN and ending with END. For example, the following block is named Sample block:

## Sample block BEGIN
sample line 1
sample line 2
sample line 3
## Sample block END

For some changes, you might need to replace a block in one template file with a block from another template file provided with Red Hat Process Automation Manager. In this case, delete the block, then paste the new block in its exact location.

Procedure

Edit the rhpam78-authoring-ha.yaml template file to make any of the following changes as necessary.

  • If you want to use PostgreSQL instead of MySQL, replace several blocks of the file, marked with comments from BEGIN to END, with blocks from the rhpam78-kieserver-postgresql.yaml file:

    1. Replace the block named MySQL database parameters with the block named PostgreSQL database parameters. (Take this block and all subsequent replacement blocks from the rhpam78-kieserver-postgresql.yaml file.)
    2. Replace the block named MySQL service with the block named PostgreSQL service.
    3. Replace the block named MySQL driver settings with the block named PostgreSQL driver settings.
    4. Replace the block named MySQL deployment config with the block named PostgreSQL deployment config.
    5. Replace the block named MySQL persistent volume claim with the block named PostgreSQL persistent volume claim.
  • If you want to use an external database server, replace several blocks of the file, marked with comments from BEGIN to END, with blocks from the rhpam78-kieserver-externaldb.yaml file, and also remove some blocks:

    1. Replace the block named MySQL database parameters with the block named External database parameters. (Take this block and all subsequent replacement blocks from the rhpam78-kieserver-externaldb.yaml file.)
    2. Replace the block named MySQL driver settings with the block named External database driver settings.
    3. Remove the following blocks of the file, marked with comments from BEGIN to END:

      • MySQL service
      • MySQL deployment config
      • MySQL persistent volume claim
Important

The standard KIE Server image includes drivers for MySQL, MariaDB, and PostgreSQL external database servers. If you want to use another database server, you must build a custom KIE Server image. For instructions, see Section 3.8, “Building a custom KIE Server extension image for an external database”.

  • If you want to change the number of replicas initially created for Business Central, on the line below the comment ## Replicas for Business Central, change the number of replicas to the desired value.

Chapter 5. Red Hat Process Automation Manager roles and users

To access Business Central or KIE Server, you must create users and assign them appropriate roles before the servers are started.

The Business Central and KIE Server use Java Authentication and Authorization Service (JAAS) login module to authenticate the users. If both Business Central and KIE Server are running on a single instance, then they share the same JAAS subject and security domain. Therefore, a user, who is authenticated for Business Central can also access KIE Server.

However, if Business Central and KIE Server are running on different instances, then the JAAS login module is triggered for both individually. Therefore, a user, who is authenticated for Business Central, needs to be authenticated separately to access the KIE Server (for example, to view or manage process definitions in Business Central). In case, the user is not authenticated on the KIE Server, then 401 error is logged in the log file, displaying Invalid credentials to load data from remote server. Contact your system administrator. message in Business Central.

This section describes available Red Hat Process Automation Manager user roles.

Note

The admin, analyst, developer, manager, process-admin, user, and rest-all roles are reserved for Business Central. The kie-server role is reserved for KIE Server. For this reason, the available roles can differ depending on whether Business Central, KIE Server, or both are installed.

  • admin: Users with the admin role are the Business Central administrators. They can manage users and create, clone, and manage the repositories. They have full access to make required changes in the application. Users with the admin role have access to all areas within Red Hat Process Automation Manager.
  • analyst: Users with the analyst role have access to all high-level features. They can model and execute their projects. However, these users cannot add contributors to spaces or delete spaces in the Design → Projects view. Access to the Deploy → Execution Servers view, which is intended for administrators, is not available to users with the analyst role. However, the Deploy button is available to these users when they access the Library perspective.
  • developer: Users with the developer role have access to almost all features and can manage rules, models, process flows, forms, and dashboards. They can manage the asset repository, they can create, build, and deploy projects, and they can use Red Hat CodeReady Studio to view processes. Only certain administrative functions such as creating and cloning a new repository are hidden from users with the developer role.
  • manager: Users with the manager role can view reports. These users are usually interested in statistics about the business processes and their performance, business indicators, and other business-related reporting. A user with this role has access only to process and task reports.
  • process-admin: Users with the process-admin role are business process administrators. They have full access to business processes, business tasks, and execution errors. These users can also view business reports and have access to the Task Inbox list.
  • user: Users with the user role can work on the Task Inbox list, which contains business tasks that are part of currently running processes. Users with this role can view process and task reports and manage processes.
  • rest-all: Users with the rest-all role can access Business Central REST capabilities.
  • kie-server: Users with the kie-server role can access KIE Server (KIE Server) REST capabilities. This role is mandatory for users to have access to Manage and Track views in Business Central.

Chapter 6. OpenShift template reference information

Red Hat Process Automation Manager provides the following OpenShift templates. To access the templates, download and extract the rhpam-7.8.0-openshift-templates.zip product deliverable file from the Software Downloads page of the Red Hat customer portal.

  • rhpam78-authoring.yaml provides a Business Central and a KIE Server connected to the Business Central. The KIE Server uses an H2 database with persistent storage. You can use this environment to author processes, services, and other business assets. For details about this template, see Section 6.1, “rhpam78-authoring.yaml template”.
  • rhpam78-authoring-ha.yaml provides a high-availability Business Central, a KIE Server connected to the Business Central, and a MySQL instance that the KIE Server uses. You can use this environment to author processes, services, and other business assets. For details about this template, see Section 6.2, “rhpam78-authoring-ha.yaml template”.

6.1.2. Objects

The CLI supports various object types. A list of these object types as well as their abbreviations can be found in the Openshift documentation.

6.1.2.1. Services

A service is an abstraction which defines a logical set of pods and a policy by which to access them. See the container-engine documentation for more information.

6.1.2.2. Routes

A route is a way to expose a service by giving it an externally reachable hostname such as www.example.com. A defined route and the endpoints identified by its service can be consumed by a router to provide named connectivity from external clients to your applications. Each route consists of a route name, service selector, and (optionally) security configuration. See the Openshift documentation for more information.

6.1.2.3. Deployment Configurations

A deployment in OpenShift is a replication controller based on a user-defined template called a deployment configuration. Deployments are created manually or in response to triggered events. See the Openshift documentation for more information.

6.1.2.3.1. Triggers

A trigger drives the creation of new deployments in response to events, both inside and outside OpenShift. See the Openshift documentation for more information.

Defines the String which is to be removed from the start of the DN to reveal the user name. This option is used together with usernameEndString and only taken into account if parseUsername is set to true.

${AUTH_LDAP_USERNAME_BEGIN_STRING}

AUTH_LDAP_USERNAME_END_STRING

Defines the String which is to be removed from the end of the DN to reveal the user name. This option is used together with usernameEndString and only taken into account if parseUsername is set to true.

${AUTH_LDAP_USERNAME_END_STRING}

AUTH_LDAP_ROLE_ATTRIBUTE_ID

Name of the attribute containing the user roles.

${AUTH_LDAP_ROLE_ATTRIBUTE_ID}

AUTH_LDAP_ROLES_CTX_DN

The fixed DN of the context to search for user roles. This is not the DN where the actual roles are, but the DN where the objects containing the user roles are. For example, in a Microsoft Active Directory server, this is the DN where the user account is.

${AUTH_LDAP_ROLES_CTX_DN}

AUTH_LDAP_ROLE_FILTER

A search filter used to locate the roles associated with the authenticated user. The input username or userDN obtained from the login module callback is substituted into the filter anywhere a {0} expression is used. The authenticated userDN is substituted into the filter anywhere a {1} is used. An example search filter that matches on the input username is (member={0}). An alternative that matches on the authenticated userDN is (member={1}).

${AUTH_LDAP_ROLE_FILTER}

AUTH_LDAP_ROLE_RECURSION

The number of levels of recursion the role search will go below a matching context. Disable recursion by setting this to 0.

${AUTH_LDAP_ROLE_NAME_ATTRIBUTE_ID}

AUTH_LDAP_PARSE_ROLE_NAME_FROM_DN

A flag indicating if the DN returned by a query contains the roleNameAttributeID. If set to true, the DN is checked for the roleNameAttributeID. If set to false, the DN is not checked for the roleNameAttributeID. This flag can improve the performance of LDAP queries.

${AUTH_LDAP_PARSE_ROLE_NAME_FROM_DN}

AUTH_LDAP_ROLE_ATTRIBUTE_IS_DN

Whether or not the roleAttributeID contains the fully-qualified DN of a role object. If false, the role name is taken from the value of the roleNameAttributeId attribute of the context name. Certain directory schemas, such as Microsoft Active Directory, require this attribute to be set to true.

${AUTH_LDAP_ROLE_ATTRIBUTE_IS_DN}

AUTH_LDAP_REFERRAL_USER_ATTRIBUTE_ID_TO_CHECK

If you are not using referrals, you can ignore this option. When using referrals, this option denotes the attribute name which contains users defined for a certain role, for example member, if the role object is inside the referral. Users are checked against the content of this attribute name. If this option is not set, the check will always fail, so role objects cannot be stored in a referral tree.

${AUTH_LDAP_REFERRAL_USER_ATTRIBUTE_ID_TO_CHECK}

AUTH_ROLE_MAPPER_ROLES_PROPERTIES

When present, the RoleMapping Login Module will be configured to use the provided file. This parameter defines the fully-qualified file path and name of a properties file or resource which maps roles to replacement roles. The format of every entry in the file is original_role=role1,role2,role3

6.2.2.4.2. Secrets

This template requires the following secrets to be installed for the application to run.

businesscentral-app-secret kieserver-app-secret

6.2.2.4.3. Clustering

Clustering in OpenShift EAP is achieved through one of two discovery mechanisms: Kubernetes or DNS. This is done by configuring the JGroups protocol stack in standalone-openshift.xml with either the <openshift.KUBE_PING/> or <openshift.DNS_PING/> elements. The templates are configured to use DNS_PING, however `KUBE_PING`is the default used by the image.

The discovery mechanism used is specified by the JGROUPS_PING_PROTOCOL environment variable which can be set to either openshift.DNS_PING or openshift.KUBE_PING. openshift.KUBE_PING is the default used by the image if no value is specified for JGROUPS_PING_PROTOCOL.

For DNS_PING to work, the following steps must be taken:

  1. The OPENSHIFT_DNS_PING_SERVICE_NAME environment variable must be set to the name of the ping service for the cluster (see table above). If not set, the server will act as if it is a single-node cluster (a "cluster of one").
  2. The OPENSHIFT_DNS_PING_SERVICE_PORT environment variables should be set to the port number on which the ping service is exposed (see table above). The DNS_PING protocol will attempt to discern the port from the SRV records, if it can, otherwise it will default to 8888.
  3. A ping service which exposes the ping port must be defined. This service should be "headless" (ClusterIP=None) and must have the following:

    1. The port must be named for port discovery to work.
    2. It must be annotated with service.alpha.kubernetes.io/tolerate-unready-endpoints set to "true". Omitting this annotation will result in each node forming their own "cluster of one" during startup, then merging their cluster into the other nodes' clusters after startup (as the other nodes are not detected until after they have started).

Example ping service for use with DNS_PING

kind: Service
apiVersion: v1
spec:
    clusterIP: None
    ports:
    - name: ping
      port: 8888
    selector:
        deploymentConfig: eap-app
metadata:
    name: eap-app-ping
    annotations:
        service.alpha.kubernetes.io/tolerate-unready-endpoints: "true"
        description: "The JGroups ping port for clustering."

For KUBE_PING to work, the following steps must be taken:

  1. The OPENSHIFT_KUBE_PING_NAMESPACE environment variable must be set (see table above). If not set, the server will act as if it is a single-node cluster (a "cluster of one").
  2. The OPENSHIFT_KUBE_PING_LABELS environment variables should be set (see table above). If not set, pods outside of your application (albeit in your namespace) will try to join.
  3. Authorization must be granted to the service account the pod is running under to be allowed to access Kubernetes' REST api. This is done on the command line.

Example 6.1. Policy commands

Using the default service account in the myproject namespace:

oc policy add-role-to-user view system:serviceaccount:myproject:default -n myproject

Using the eap-service-account in the myproject namespace:

oc policy add-role-to-user view system:serviceaccount:myproject:eap-service-account -n myproject

6.3. OpenShift usage quick reference

To deploy, monitor, manage, and undeploy Red Hat Process Automation Manager templates on Red Hat OpenShift Container Platform, you can use the OpenShift Web console or the oc command.

For instructions about using the Web console, see Create and build an image using the Web console.

For detailed instructions about using the oc command, see CLI Reference. The following commands are likely to be required:

  • To create a project, use the following command:

    $ oc new-project <project-name>

    For more information, see Creating a project using the CLI.

  • To deploy a template (create an application from a template), use the following command:

    $ oc new-app -f <template-name> -p <parameter>=<value> -p <parameter>=<value> ...

    For more information, see Creating an application using the CLI.

  • To view a list of the active pods in the project, use the following command:

    $ oc get pods
  • To view the current status of a pod, including information whether or not the pod deployment has completed and it is now in a running state, use the following command:

    $ oc describe pod <pod-name>

    You can also use the oc describe command to view the current status of other objects. For more information, see Application modification operations.

  • To view the logs for a pod, use the following command:

    $ oc logs <pod-name>
  • To view deployment logs, look up a DeploymentConfig name in the template reference and enter the following command:

    $ oc logs -f dc/<deployment-config-name>

    For more information, see Viewing deployment logs.

  • To view build logs, look up a BuildConfig name in the template reference and enter the command:

    $ oc logs -f bc/<build-config-name>

    For more information, see Accessing build logs.

  • To scale a pod in the application, look up a DeploymentConfig name in the template reference and enter the command:

    $ oc scale dc/<deployment-config-name> --replicas=<number>

    For more information, see Manual scaling.

  • To undeploy the application, you can delete the project by using the command:

    $ oc delete project <project-name>

    Alternatively, you can use the oc delete command to remove any part of the application, such as a pod or replication controller. For details, see Application modification operations.
