Jenkins 2.528.2 Upgrade: Jobs Missing in UI and Plugin Updates Causing CrashLoopBackOff

Using Jenkins

Hi All,

Hi Everyone,

I recently upgraded my Jenkins setup to version 2.528.2 using Helm. After the upgrade, the Jenkins pods initially went into a CrashLoopBackOff state. I was able to fix that issue, and now the pods are up and stable.

Inside the Jenkins pods, I can see all my existing directories and job configurations under $JENKINS_HOME. However, in the Jenkins UI, I am only able to see the folders/directories, and the jobs inside those folders are missing.

Additionally, the new Jenkins UI prompts me to update the plugins to the latest versions. When I attempt to update the plugins, the Jenkins pod again goes into CrashLoopBackOff.

I have verified that the EKS version is 1.30, which should be supported by Jenkins 2.528.2, so this does not appear to be a Kubernetes compatibility issue.

Has anyone faced a similar issue after upgrading Jenkins? Any guidance on resolving the missing jobs and safely updating plugins without crashing Jenkins would be greatly appreciated.

Thank you in advance.

I assume that some plugins can’t be loaded. And when among them is the workflow-job plugin, then all your pipeline jobs can’t be loaded and are then not shown. You should see that already when you go to the manage page of Jenkins.
You should check your Jenkins logs for any errors about loading plugins and then start fixing them.
