Camel route using ActiveMQ in Karaf container

Primary LanguageJava

Camel AMQ QuickStart

This quickstart demonstrates how to connect to AMQ Broker and use JMS messaging between two Camel routes.

Important
 The version of AMQ Broker has to be at least 1.2

In this example we will use two containers, one container to run as an AMQ Broker instance, and another as a client to the broker, where the Camel routes are running.

This quickstart requires AMQ Broker to have been deployed and running first. To install AMQ Broker into OpenShift or Kubernetes follow documentation.

Quickstart uses the standard address space and requires standard authentication. For address space and queue definition standard-small-queue, standard_unlimited plans are used, therefore make sure you have also installed example plans, roles and standard authentication service.

Important
 This quickstart can run in 1 mode: on Kubernetes / OpenShift Cluster. Quickstart requires Java 8 or Java 11 (fuse-karaf-openshift-jdk11-rhel8 image is used to build in Java 11)

Running the Quickstart on a single-node Kubernetes/OpenShift cluster

Important
 You need to run this example on Container Development Kit 3.3 or OpenShift 3.7. Both of these products have suitable Fuse images pre-installed. If you run it in an environment where those images are not preinstalled follow the steps described in Running the Quickstart on a single-node Kubernetes/OpenShift cluster without preinstalled images.

A single-node Kubernetes/OpenShift cluster provides you with access to a cloud environment that is similar to a production environment.

If you have a single-node Kubernetes/OpenShift cluster, such as Minishift or the Red Hat Container Development Kit, installed and running, you can deploy your quickstart there.

  1. Log in to your OpenShift cluster:

    $ oc login -u developer -p developer

  2. Create a new OpenShift project for the quickstart:

    $ oc new-project MY_PROJECT_NAME

  3. Change the directory to the folder that contains the extracted quickstart application (for example, my_openshift/karaf-camel-amq) :

    $ cd my_openshift/karaf-camel-amq

  4. Before running the quickstart, you need to configure AMQ Broker (to create user and queue - both as an admin). Run the following commands to apply configuration files:

    $ oc login -u system:admin
$ oc apply -f src/main/resources/k8s

  5. Wait until address space is ready:

    $ oc get addressspace karaf-camel-amq -o jsonpath={.status.isReady}

  6. Build and deploy the project to the OpenShift cluster:

    $ mvn clean -DskipTests oc:deploy -Popenshift

  7. In your browser, navigate to the MY_PROJECT_NAME project in the OpenShift console. Wait until you can see that the pod for the karaf-camel-amq has started up.

  8. On the project’s Overview page, navigate to the details page deployment of the karaf-camel-amq application: https://OPENSHIFT_IP_ADDR:8443/console/project/MY_PROJECT_NAME/browse/rc/karaf-camel-amq-NUMBER_OF_DEPLOYMENT?tab=details.

  9. Switch to tab Logs and then see the messages sent by Camel:

A single-node Kubernetes/OpenShift cluster provides you with access to a cloud environment that is similar to a production environment.

If you have a single-node Kubernetes/OpenShift cluster, such as Minishift or the Red Hat Container Development Kit, installed and running, you can deploy your quickstart there.

  1. Log in to your OpenShift cluster:

    $ oc login -u developer -p developer

  2. Create a new OpenShift project for the quickstart:

    $ oc new-project MY_PROJECT_NAME

  3. Import base images in your newly created project (MY_PROJECT_NAME) according to documentation.

  4. Change the directory to the folder that contains the extracted quickstart application (for example, my_openshift/karaf-camel-amq) :

    $ cd my_openshift/karaf-camel-amq
