Chapter 10. Integrating a Camel application with the A-MQ broker


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

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

This quickstart demonstrates how to connect a Spring Boot application to AMQ Broker 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. Create a new project for quickstart, for example:.

    oc new-project quickstart
  3. Retrieve the quickstart project by using the Maven archetype:

    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-sb2-790047-redhat-00004/archetypes-catalog-2.2.0.fuse-sb2-790047-redhat-00004-archetype-catalog.xml -DarchetypeGroupId=org.jboss.fuse.fis.archetypes -DarchetypeArtifactId=spring-boot-camel-amq-archetype -DarchetypeVersion=2.2.0.fuse-sb2-790047-redhat-00004
  4. Navigate to the quickstart directory fuse710-spring-boot-camel-amq.

    cd fuse710-spring-boot-camel-amq
  5. Run the following commands to apply configuration files to AMQ Broker. These configuration files create the AMQ Broker user and the queue, both with the admin privileges.

    oc login -u admin -p admin
    
    oc apply -f src/main/resources/k8s
  6. Create the ConfigMap for the application, for example:

    kind: ConfigMap
    apiVersion: v1
    metadata:
      name: spring-boot-camel-amq-config
      namespace: quickstarts
    data:
      service.host: 'fuse-broker-amqps-0-svc'
      service.port.amqp: '5672'
      service.port.amqps: '5671'
  7. Run the mvn command to deploy the quickstart to the OpenShift server, by using the ImageStream from Step 3:

    mvn oc:deploy -Popenshift -Djkube.generator.fromMode=istag -Djkube.generator.from=openshift/fuse-java-openshift:1.9
  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 fuse710-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 fuse710-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.

  9. To view the routes on the web interface, click Open Java Console and check the messages in the AMQ queue.
