Resources Cleanup / Garbage collector

[fernandonogueira]

Hi! 👋🏼

I'm using Keptn with the auto app discovery enabled.
I'd like to know if there is a recommended way to clean up resources - Mainly KeptnAppVersions and KeptnWorkloadVersions.

Update: My main issue is that the versions are piling up, and the Prometheus scraping is starting to become problematic.

Thanks! 🙇🏼

Hello!

Thank you for reaching out. Currently we do not have an automated way to cleanup old resources, but for this use case, you can use kube-janitor.

Regarding the KeptnAppVersion and KeptnWorkloadVersion resources, it should be safe to remove the old versions of these resources except the latest one (the version which is present in the corresponding KeptnApp or KeptnWorkload). Those versions of KeptnAppVersion and KeptnWorkloadVersion should have phase equal to Completed or Deprecated.

Please also be aware, that if you are using KeptnTasks or KeptnEvaluations, which were ran as part of the application lifecycle deployment, those will get deleted as well (if you have cascading deletion enabled on your cluster).

Hope this helps! If you have any other questions, please reach out.
