Project for creating a Node.js 6 based Jenkins Slave container image (for use in OpenShift).

Build it yourself or try using the Dockerhub version (tag latest is CentOS, tag rhel7-latest is Red Hat E.Linux).

This is targeted towards OpenShift 3.7 and later, CentOS/RHEL7, and Node.js 6.

Assuming you already have an OpenShift cluster up and running and your Jenkins pipeline setup. You need to:

1. Update the Jenkins Kubernetes plugin to reference the builder image. Open your Jenkins webconsole and in Jenkins->Manage Jenkins->Configure System. Then look in Cloud->Kubernetes->Kubernetes Pod Template. Depending on where your container image lives, the new setup should look something like this:

2. Update your pipeline to reference the correct slave image by name. Something like:

   pipeline {
       agent {
           node {
               // spin up a node.js slave pod to run this build on
               label 'nodejs6'
           }
       }
   
       [THE STAGES AND STEPS...]
   

   or with the older syntax:

   node('nodejs6') {
       stage('build') {
           openshiftBuild(buildConfig: '${NAME}', showBuildLogs: 'true')
       }
       
       [OTHER STAGES...]
