Openshift 3 FIS sample

CDI Camel HTTP QuickStart

This example shows how to work with Camel in the Java Container using CDI to configure components, endpoints and beans.

This quickstart is the client side which embeds a Camel route that triggers every 5th second, and calls a remote HTTP service and logs the response.

The server side provides the remote HTTP service is the quickstart-cdi-camel-jetty quicstart which must be up and running.

Building

The example can be built with

mvn clean install

Running the example locally

The example can be run locally using the following Maven goal:

mvn clean install exec:java

Running the example in fabric8

It is assumed that OpenShift platform is already running. If not you can find details how to Install OpenShift at your site.

The example can be built and deployed using a single goal:

mvn -Pf8-deploy

When the example runs in OpenShift, you can use the OpenShift client tool to inspect the status

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 OpenShift web console to manage the running pods, and view logs and much more.

Calling the remote service from a shell script

You can also call the remote HTTP service from a shell script. We have provided a script named src/test/resources/hitme-f8.sh (no script for windows) in the source code for the quickstart, not in the docker image, which will call the service once per second.

You may need to add execution permission to the script before you can execute it

chmod +x src/test/resources/hitme-f8.sh

And then run the script

src/test/resources/hitme-f8.sh

While the script runs, you can try to scale up or down the number of pods on the remote HTTP service using either the OpenShift web console, or from the command line using the openshift client

oc scale --replicas=3 replicationcontrollers quickstart-cdi-camel-jetty

Running the example using OpenShift S2I template

The example can also be built and run using the included S2I template quickstart-template.json.

The application can be run directly by first editing the template file and populating S2I build parameters, including the required parameter GIT_REPO and then executing the command:

oc new-app -f quickstart-template.json

Alternatively the template file can be used to create an OpenShift application template by executing the command:

oc create -f quickstart-template.json
