Overview

Set Up a Jenkins CI/CD Pipeline

Create Required Image Streams

Create an Image Stream

Create Required Projects

Create the following projects:

1. A project for the CI/CD components, named "cicd":

oc new-project cicd --display-name="CI/CD pipeline with Jenkins"

2. A project to host development-stage containers and processes, named "dev":

oc new-project dev --display-name="Tasks - Dev"

3. A project to host publicly-accessible application produced by the CI/CD pipeline, named "stage":

oc new-project stage --display-name="Tasks - Stage"

Grant Jenkins Needed Privileges for the Projects that Require CI/CD Services

For reasons behind these actions, see:

Jenkins and OpenShift - Security Considerations
oc policy add-role-to-user edit system:serviceaccount:cicd:jenkins -n dev
oc policy add-role-to-user edit system:serviceaccount:cicd:jenkins -n stage

Create the CI/CD Components

oc project cicd

oc process -f ./cicd-template.yaml --param DEV_PROJECT=dev --param STAGE_PROJECT=stage \
| oc create -f - 

A template example for OpenShift 3.5 is available at https://github.com/OpenShiftDemos/openshift-cd-demo/blob/ocp-3.5/cicd-template.yaml. A version is also available here: OpenShift CICD Template Example.

Note that "jenkins-persistent" and "jenkins-ephemeral" are available templates in the "openshift" project, they probably can be also used:

oc get templates -n openshift | grep jenkins

Configure Jenkins

oc project cicd
oc set resources dc/jenkins --limits=memory=1Gi
