How To Clean Up Container Registry

I’m looking for a way to automatically clean up old files from my Docker Container Registry.

Currently I’m using the following:

doctl registry repository list-tags myrepo

Then I can delete old tags like this:

doctl registry repository delete-tag myrepo mytag

However, these still take up space. I can use the Digest but how can I find the digests of each image programmatically?

I’ve looked at

doctl registry repository list 

But this only gives me the latest tag.

I have resolved this after reading more carefully through the documentation.

By adding the --include-untagged-manifests I’m able to remove any untagged manifests without having to specify a digest.

example:

yes | doctl registry garbage-collection start --include-untagged-manifests
