NAME DESCRIPTION GENERATOR VALUE
JENKINS_SERVICE_NAME The name of the OpenShift Service exposed for the Jenkins container. jenkins
JNLP_SERVICE_NAME The name of the service used for master/slave communication. jenkins-jnlp
ENABLE_OAUTH Whether to enable OAuth OpenShift integration. If false, the static account 'admin' will be initialized with the password 'password'. true
MEMORY_LIMIT Maximum amount of memory the container can use. 1Gi
NAMESPACE The OpenShift Namespace where the Jenkins ImageStream resides. openshift
DISABLE_ADMINISTRATIVE_MONITORS Whether to perform memory intensive, possibly slow, synchronization with the Jenkins Update Center on start. If true, the Jenkins core update monitor and site warnings monitor are disabled. false
JENKINS_IMAGE_STREAM_TAG Name of the ImageStreamTag to be used for the Jenkins image. jenkins:2
JENKINS_UC_INSECURE Whether to allow use of a Jenkins Update Center that uses invalid certificate (self-signed, unknown CA). If any value other than 'false', certificate check is bypassed. By default, certificate check is enforced. false

- We need to set up a pipeline to build our software, but we want to use the build that is built into OpenShift. The following command will create a build configuration (or “build config,” which is an object of type “BuildConfig”), which has the instructions we give to OpenShift to tell it how to build our application. In this particular case, we’re creating a pipeline that, in turn, has the build instructions:
oc create -f https://github.com/raw/openshift/origin/master/examples/jenkins/pipeline/nodejs-sample-pipeline.yaml
oc get buildconfigs
