This quickstart demonstrates how to connect a Spring-Boot application to an ActiveMQ broker and use JMS messaging between two Camel routes using Kubernetes or OpenShift.
In this example we will use two containers, one container to run as a ActiveMQ broker, and another as a client to the broker, where the Camel routes is running.
This quickstart requires the ActiveMQ broker has been deployed and running first. This can be done from the web console from the Apps page, and then install the messaging application.
The example can be built with
mvn clean install
The example can be run locally using the following Maven goal:
mvn spring-boot:run
It is assumed a running Kubernetes platform is already running. If not you can find details how to get started.
Assuming your current shell is connected to Kubernetes or OpenShift so that you can type a command like
kubectl get pods
or for OpenShift
oc get pods
Then the following command will package your app and run it on Kubernetes:
mvn fabric8:run
To list all the running pods:
oc get pods
Then find the name of the pod that runs this quickstart, and output the logs from the running pods with:
oc logs <name of pod>
You can also use the fabric8 developer console to manage the running pods, and view logs and much more.
The example includes a Arquillian Cube Openshift Kubernetes Integration Test. Once the container image has been built and deployed in Kubernetes, the integration test can be run with:
mvn test -Dtest=*KT
The test is disabled by default and has to be enabled using -Dtest. Arquillian Cube provide more information on writing full fledged black box integration tests for Kubernetes.
You can find more details about running this quickstart on the website. This also includes instructions how to change the Docker image user and registry.
