Set Up a CI/CD Pipeline

Set Up a Project-Collocated jenkins-persistent-Based Jenkins

Set Up a Dedicated CI/CD Project jenkins-persistent-Based Jenkins

Set Up a Standalone, cicd-template.yaml-Based Jenkins

Configure the Jenkins Pipeline with Pipeline Plug-In

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

Pipeline -> Definition -> Pipeline script:

node {
  stage ("Build") {
    echo '*** Build Starting ***'
    openshiftBuild apiURL: 'https://openshift.default.svc.cluster.local', authToken: '', bldCfg: 'hello-nodejs', buildName: '', checkForTriggeredDeployments: 'false', commitID: '', namespace: '', showBuildLogs: 'false', verbose: 'false', waitTime: ''
    openshiftVerifyBuild apiURL: 'https://openshift.default.svc.cluster.local', authToken: '', bldCfg: 'hello-nodejs', checkForTriggeredDeployments: 'false', namespace: '', verbose: 'false'
    echo '*** Build Complete ***'
  }
  stage ("Deploy") {
    echo '*** Deployment Starting ***'
    openshiftDeploy apiURL: 'https://openshift.default.svc.cluster.local', authToken: '', depCfg: 'hello-nodejs', namespace: '', verbose: 'false', waitTime: ''
    openshiftVerifyDeployment apiURL: 'https://openshift.default.svc.cluster.local', authToken: '', depCfg: 'hello-nodejs', namespace: '', replicaCount: '1', verbose: 'false', verifyReplicaCount: 'false', waitTime: ''
    echo '*** Deployment Complete ***'
  }
  stage ("Verify") {
    echo '*** Service Verification Starting ***'
    openshiftVerifyService apiURL: 'https://openshift.default.svc.cluster.local', authToken: '', namespace: '', svcName: 'hello-nodejs', verbose: 'false'
    echo '*** Service Verification Complete ***'
  }
}

Set up Continuous Delivery

Set up a development, QA and production project.
