If you are running a private v2 docker registry, and you are storing your data on disk, running this bash script from the machine where the data lives will let you fully delete an image or tag

delete-docker-registry-image

Install

curl https://raw.githubusercontent.com/burnettk/delete-docker-registry-image/master/delete_docker_registry_image | sudo tee /usr/local/bin/delete_docker_registry_image >/dev/null
sudo chmod a+x /usr/local/bin/delete_docker_registry_image

Run

Set up your data directory via an environment variable:

export REGISTRY_DATA_DIR=/opt/registry_data/docker/registry/v2

You can also just edit the script where this variable is set to make it work for your setup.

Almost delete a repo:

delete_docker_registry_image --image testrepo/awesomeimage --dry-run

Actually delete a repo (remember to shut down your registry first):

delete_docker_registry_image --image testrepo/awesomeimage

Delete one tag from a repo:

delete_docker_registry_image --image testrepo/awesomeimage:supertag

Example:

./clean_old_versions.py --image '^repo/sitor*' --include '^0.1.*' -l 2
