Chapter 9. Integrating a Camel application with the A-MQ broker

This tutorial shows how to deploy a quickstart using the A-MQ image.

9.1. Building and deploying a Spring Boot Camel A-MQ quickstart

This quickstart demonstrates how to connect a Spring Boot application to AMQ Online and use JMS messaging between two Camel routes using Fuse on OpenShift.

Prerequisites

Procedure

  1. Log in to the OpenShift server as a developer.

    oc login -u developer -p developer
  2. Log in to the openshift project.

    oc project openshift
  3. Create the quickstart project using the Maven workflow.

    mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate \
    -DarchetypeCatalog=https://maven.repository.redhat.com/ga/io/fabric8/archetypes/archetypes-catalog/2.2.0.fuse-770011-redhat-00003/archetypes-catalog-2.2.0.fuse-770011-redhat-00003-archetype-catalog.xml \
    -DarchetypeGroupId=org.jboss.fuse.fis.archetypes \
    -DarchetypeArtifactId=spring-boot-camel-amq-archetype \
    -DarchetypeVersion=2.2.0.fuse-770011-redhat-00003
  4. The archetype plug-in switches to interactive mode to prompt you for the remaining fields.

    Define value for property 'groupId': : org.example.fis
    Define value for property 'artifactId': : fuse77-spring-boot-camel-amq
    Define value for property 'version':  1.0-SNAPSHOT: :
    Define value for property 'package':  org.example.fis: :
    Confirm properties configuration:
    groupId: org.example.fis
    artifactId: fuse77-spring-boot-camel-amq
    version: 1.0-SNAPSHOT
    package: org.example.fis
    Y: :Y

    When prompted, enter org.example.fis for the groupId value and fuse77-spring-boot-camel-amq for the artifactId value. Accept the defaults for the remaining fields.

  5. Navigate to the quickstart directory fuse77-spring-boot-camel-amq.

    cd fuse77-spring-boot-camel-amq
  6. Run the following commands to apply configuration files to AMQ Online. These configuration files create the AMQ Online user and the queue, both with the admin privileges.

    oc login -u system:admin
    oc apply -f src/main/resources/k8s
  7. Run the mvn command to deploy the quickstart to the OpenShift server.

    mvn fabric8:deploy -Popenshift
  8. To verify that the quickstart is running successfully:

    1. Navigate to the OpenShift web console in your browser (https://OPENSHIFT_IP_ADDR, replace OPENSHIFT_IP_ADDR with the IP address of the cluster) and log in to the console with your credentials (for example, with username developer and password, developer).
    2. In the left hand side panel, expand Home and then click Status to view the Project Status page for openshift project.
    3. Click fuse77-spring-boot-camel-amq to view the Overview information page for the quickstart.
    4. In the left hand side panel, expand Workloads.
    5. Click Pods and then click fuse77-spring-boot-camel-amq-xxxxx. The pod details for the quickstart are displayed.
    6. Click Logs to view the logs for the application.

      The output shows the messages are sent successfully.
