[FIXED] OCP - Jenking persistent - old version?

Issue

I have an OCP 4.4.11 running on IBM cloud. I decided to install jenkins-persistent that's provided by RedHat. But the version installed is 2.222.1, which is quite old I would say. Is it possible to update to some latest one?

The jenkins image itself seems to be coming from openshift's imagestream:

Thanks for any pointers.

Solution

Jenkins image available with OCP are based on Jenkins LTS released

(Almost) each time you'll upgrade OCP, the image and version of Jenkins will also be upgraded, so it is not advised to play with the deployment. The OCP Jenkins image embeds many useful plugins. You can safely upgrade the plugins from the Jenkins UI if they are compatible with the version of Jenkins (The UI will tell you if not)

In any case, nothing force you to use the Jenkins images provided with OCP, you can deploy your own flavor of Jenkins and add the plugins required to interact with OCP itself (Kubernetes plugin, OCP plugin, configure OIDC for jenkins to OCP etc)
