The Jenkins components need to access the OpenShift API for various operations: access container images, etc. so they need to be granted sufficient privileges to invoke the OpenShift API for the projects requiring CI/CD pipeline services - in our case "dev" and "stage":

ALL THIS MUST BE REFACTORED

Resources

This is the memory consumption based on a test installation:

  • jenkins/jenkins-jnlp pod: 880 MB
  • nexus pod: 1.5 GB
  • gogs pod: 140 MB
  • gogs postgresql pod: 42 MB
  • sonar pod: 2.0 GB
  • sonar postgresql pod: 77 MB

Set Up a CI/CD Pipeline

Configure the Jenkins Pipeline with Pipeline Plug-In

New Item -> "hello-nodejs-pipeline" -> Pipeline -> OK

Pipeline -> Definition -> Pipeline script:

Set up Continuous Delivery

Set up a development, QA and production project.
