An example demonstrating Jenkins S2I features for installing plugins, configuring jobs, Jenkins, etc and using slave pods for Jenkins jobs.

1. Create a new OpenShift project, where the Jenkins server will run:

$ oc new-project ci --display-name="CI/CD"

2. Give the Jenkins Pod service account rights to do API calls to OpenShift. This allows us to do the Jenkins Slave image discovery automatically.

$ oc policy add-role-to-user edit -z default -n ci

3. Install the provided OpenShift templates:

$ oc create -f jenkins-slave-builder-template.yaml   # For converting any S2I to Jenkins slave
$ oc create -f jenkins-master-s2i-template.yaml      # For creating pre-configured Jenkins master using Jenkins S2I

5. Build Jenkins slave image.

$ oc new-app jenkins-slave-builder

4. Create Jenkins master. You can customize the source repo and other configurations through template parameters. Note that this example doesn't define any persistent volume. You need to define storage in order to retain Jenkins data on container restarts.

$ oc new-app jenkins-master-s2i
