Overview

This is the oldest Jenkins/OpenShift integration plugin, which executes inside Jenkins and implements a series of REST flows that interface with the OpenShift master server via its exposed API. This plugin does not require the oc binary to be present on the host that executes the plugin logic. Other plugin that may be used starting with OpenShift 3.7 is OpenShift Jenkins Pipeline DSL Plugin (jenkins-client-plugin). The "OpenShift Plugin for Jenkins" is currently in maintenance mode.

Pipeline Examples

• jenkins-plugin DSL: https://github.com/NovaOrdis/playground/tree/master/openshift/jenkins-plugin/Jenkinsfile-jenkins-plugin-DSL.groovy
• Low-level maven and oc interaction: https://github.com/NovaOrdis/playground/tree/master/openshift/jenkins-plugin/Jenkinsfile-mvn-oc.groovy
• Maven slave node pipeline: https://github.com/openshift/origin/blob/master/examples/jenkins/pipeline/maven-pipeline.yaml
• Blue/Green deployment pipeline: https://github.com/openshift/origin/blob/master/examples/jenkins/pipeline/bluegreen-pipeline.yaml

Pipeline DSL

The pipeline can be scripted or can be specified in a declarative format. A scripted DSL element looks like this:

openshiftBuild(buildConfig: 'something')

A declared DSL element looks like this:

openshiftBuild bldCfg: 'something', apiURL: 'https://openshift.default.svc.cluster.local', ...
