You must install Jenkins on OpenShift.
Create a project for the Jenkins deployment:
oc new-project YOUR-JENKINS-PROJECT
Create a new Jenkins application using the jenkins-ephemeral template.
oc new-app openshift/jenkins-ephemeral -p MEMORY_LIMIT=2048Mi
The
jenkins-ephemeraltemplate does not persist data. If you restart the Jenkins pod, you will lose data. Use thejenkins-persistenttemplate to persist your Jenkins data.
This demo uses Jenkins on OpenShift, which requires Jenkins Agents to run specific runtimes.
To create Node.js agent, run:
oc process -f jenkins/jenkins-agent-template.yml -p NAME=jenkins-agent-node-14 -p SOURCE_CONTEXT_DIR=jenkins/node14 | oc apply -f -
For the Python agent, run:
oc process -f jenkins/jenkins-agent-template.yml -p NAME=jenkins-agent-python-3 -p SOURCE_CONTEXT_DIR=jenkins/python3 | oc apply -f -
For Cypress:
oc process -f jenkins/jenkins-agent-template.yml -p NAME=jenkins-agent-cypress -p SOURCE_CONTEXT_DIR=jenkins/cypress | oc apply -f -
This example uses a test environment to make deployments specific to branches. Each branch generates will generate its own deployments
Create the test project:
oc new-project YOUR-TEST-PROJECT
Allow Jenkins to deploy to this project:
oc policy add-role-to-user edit system:serviceaccount:YOUR-JENKINS-PROJECT:jenkins -n YOUR-TEST-PROJECT
Create the stage project:
oc new-project YOUR-STAGE-PROJECT
Allow Jenkins to deploy to this project:
oc policy add-role-to-user edit system:serviceaccount:YOUR-JENKINS-PROJECT:jenkins -n YOUR-STAGE-PROJECT
You need to create the deployments before running the Jenkins pipeline.
