Instance Method Details
#execute ⇒ Object
Replace a tag on the registry with a dummy tag. This is a hack as the registry doesn’t support deleting individual tags. This code effectively pushes a dummy image and assigns the tag to it. This way when the tag is deleted only the dummy image is affected. This is used to preserve compatibility with third-party registries that don’t support fast delete. See gitlab.com/gitlab-org/gitlab/issues/15737 for a discussion
