Deleting single tag is delteing all of them about docker-registry-browser HOT 6 CLOSED

Hi @tylkotroszke,

thanks for reporting this bug. I was able to reproduce it by the following steps:

1. Create a few docker images locally with the same content but different tags:

$ docker pull busybox

$ docker tag busybox localhost:5000/some/image:tag1
$ docker tag busybox localhost:5000/some/image:tag2
$ docker tag busybox localhost:5000/some/image:tag3

$ docker push localhost:5000/some/image:tag1
$ docker push localhost:5000/some/image:tag2
$ docker push localhost:5000/some/image:tag3

2. Opening the Docker Registry Browser and delete the tag "tag1"
3. Tags "tag2" and "tag3" are also gone

When I tried the same with tags having different contents I was not able to reproduce.

After a bit of research I've learned that there is currently no API to delete a single tag in the registry.

The endpoint I'm using is designed to delete the image referenced by the tag and not the tag reference itself. So basically this issue could only be solved by a new endpoint in the registry itself.

For now the only thing I could do is to change the warning text and mention that deleting the tag will also delete also delete all tags referencing the same image-version.

What do you think?

I see, you are right we were checking that on image with same content. It would be nice to have such a information when trying to delete tag. It was really confusing when all tags were deleted that why we created issue :)

👍 Sure will add it.

I've added the warning message now. Will be available as v1.2.2 tag or in latest soon.

Hi, this seems to be supported now (https://serverfault.com/questions/872332/easy-way-to-remove-a-tag-from-a-private-docker-registry/872336#872336 / https://github.com/opencontainers/distribution-spec/blob/v1.0/spec.md#deleting-tags), could this be implemented?

@u1735067 I just had a look and the feature isn't yet available in the latest release of the registry (2.8.1). They don't seem to add new features in 2.x. Let's wait for 3.0 then.
