clean_registry

Clean the Docker Registry by removing untagged repositories and running the garbage collector in Docker Registry >= 2.4.0

The optional -x flag may be used to remove the specified repositories or tagged images.

NOTES:

• This script stops the Registry container during cleanup to prevent corruption, making it temporarily unavailable to clients.
• This script assumes local storage (the filesystem storage driver).
• This script may run stand-alone or dockerized. To run stand-alone, you must install docker-py and pyyaml with:
  

pip3 install docker pyyaml

Usage:

clean_registry.py [OPTIONS] CONTAINER [REPOSITORY[:TAG]]...
Options:
        -x, --remove    Remove the specified images or repositories.
        -q, --quiet     Supress non-error messages.
        -V, --version   Show version and exit.

Docker usage:

docker run --rm --volumes-from CONTAINER -v /var/run/docker.sock:/var/run/docker.sock ricardobranco/clean_registry [OPTIONS] CONTAINER [REPOSITORY[:TAG]]...
