Re: Prune images in OpenShift Registry

I'd recommend you reading through [1] which has a thorough description of all three supported
prune commands (builds, deployments and images). Each explaining in details all possible flags,
as well as which objects are eligible for pruning.

In general, to answer your first question - yes, removing images older than 60 days is doable
with --keep-younger-than=1440h but that will only remove not used images. So before that
you need to remove deployments which also has several [1] possibilities what and when
should be removed.

If you're still experiencing any issues, or have more questions, I'd be happy to answer them.

I see only one image which oadm prune image will delete (this is an image from which I manually deleted all its deployments and whole project). So I would expect I actually first need to perform oadm prune deployments before I can delete other old images? Are there other restrictions? (we don't build, only deploy).

Onderwerp: Prune images in OpenShift Registry


I want to delete all images in our openshift registry which are older than 60 days. Is this possible?

Another option could be to delete all images except the images which were used in the last 20 deploys. Is this possible?

I saw the prune image command but I don't really understand it and also the output is pretty unclear. I performed a dry-run.

Is it really deleting from the registry of from the server?

Do I have to edit registry configuration. (I have a bit experience with this on real docker registries (not in openshift)).
