Issue: Use Jenkins image with OAUTH

Solution:

Step 1:

Deleted ALL the jenkins objects from the config

• Route
• service
• endpoint
• replication controllers
• pvc
• role binding
• service account (Note: Leave the secrets as is)

Via commandline (oc) you can delete most of the objects:

oc describe dc jenkins-pipeline-svc|more (look for the label with template=)

oc get all -l template=<label-id-for-jenkins> -n <namespace>

oc delete all -l template=<label-id-for-jenkins> -n <namespace>

Go to UI and verify all jenkins objects are gone. Remove whats left behind.

Step 2:

Add to project Select Continuous Integration & Deployment Select BC Gov Pathfinder Jenkins (Persistent)

Step 3:

Configure Jenkins

• Add env variable JAVA_OPTS value -XX:MaxMetaspaceSize=512m to jenkins config
• In jenkins
  • Maven Kubernet node (cpu, memory, namespace)
    • Environment Vars (EnvVars) : OPENSHIFT_JENKINS_JVM_ARCH = x86_64
    • Requested Mem 1Gi; Limited Mem 4Gi
  • Configure timeouts Build Verification 180 (was 60)
  • Re-apply other changes you might have done (like extra env vars, etc) NOTE:
