Jenkins on OpenShift

This repo contains resources used to build a pipeline for building new Jenkins container image for OpenShift.

Building a new image - step by step

Create a new project
```
oc new-project test-jenkins-builder
```
For OKD/Minishift import jenkins-persistent template - for some reasons it's missing in newer version (skip it if your cluster already has it)
```
oc apply -f https://raw.githubusercontent.com/openshift/origin/master/examples/jenkins/jenkins-persistent-template.json -n openshift
```

Start a new Jenkins instance

oc process -n openshift jenkins-persistent -p MEMORY_LIMIT=1024M|oc apply -f- -n test-jenkins-builder
oc set env dc/jenkins \
OVERRIDE_PV_CONFIG_WITH_IMAGE_CONFIG=true \
OVERRIDE_PV_PLUGINS_WITH_IMAGE_PLUGINS=true \
CASC_JENKINS_CONFIG=/var/lib/jenkins/jenkins-casc.yaml

Assign an admin role to jenkins

oc adm policy add-cluster-role-to-user admin -z jenkins

Create a pipeline

oc process -f jenkins-pipeline-template.yaml|oc apply -f- -n test-jenkins-builder

Run the pipeline job
```
oc start-build build-image-jenkins-master
```
Log in to Jenkins and check the build progress. Approve its promotion to openshift project to make it available to other users on your cluster.
