Jenkins-X – Customize release version

Posted on July 3, 2020 by lysender

We have an existing infrastructure in GCP using Kubernetes and Jenkis-X. When one of the owner decided to leave the business due to personal reasons, we ended up moving all the repositories to the other owner. This caused the releases to reset to v0.0.1 and blocked all new releases since the package files already exists. We did this basic trick to jump from v0.0.1 to the version we choose.

TLDR; we just created a dummy release in the new repo and name it after the last version from the previous repo. For example, if the last version was v0.0.69 then just create the same version in the new repo. Jenkis-X will just increment the latest version and we’re good!

That’s it! I’ll be posting more Kubernetes and Jenkins-X soon.
