Deleting using 'tags-like' keeps digest, not removing tag

[PBXg33k]

We're trying to use this tool to keep our internal registry clean using our CI/CD infrastructure, but i seem to be unable to delete tags from our registry.

Our CI build images and pushes these to the registry, upon build only one tag is used based on the branch name, so we can exclude that digest are referenced by multiple tags.

I would expect the tool to delete the unused/untagged digest since it's not refered by any other tag than the one we have pushed from CI.

% docker run --rm anoxis/registry-cli -r $REGISTRY_URL --delete --num 0 --tags-like "feature-tag" "feature-tag-frontend"
Will delete all but 0 last tags

Am i executing the script incorrectly or is this a bug?

Registry is running on the registry:2.7.1 image.

Why do you expect that orphan digests will be created after build? From your command I can see that you are passing --num 0 which means that no tags will be deleted. Please try putting some non-zero number here.

I'm not expecting orphaned digest to be created, i just wanted to doublecheck and explicitly mentioned that the created layers are only referenced by a single tag, and removing that that would render them orphaned.

Running the same command without --num or --num having a non-zero value generates the same output, and not deleting the tag given to --tags-like
