Docker Registry V2 Helper

This tool can help you to mark images filtered by glob as "need to be removed" for the next cycle of garbage collecting

To use this tool just run docker-registry-v2-helper with specified params:

root@machine:$ docker-registry-v2-helper -h

Usage of docker-registry-v2-helper:
  -glob string
        Glob for image filtering by tags (If empty will be match nothing)
  -password string
        Please set Password if basic auth enabled for Docker Registry V2
  -url string
        Docker Registry V2 address (HTTPS / HTTP)  (default "https://registry.docker.io")
  -username string
        Please set Username if basic auth enabled for Docker Registry V2

Example params to remove all image tags that match glob develop-*:

root@machine:$ docker-registry-v2-helper -glob "develop-*" -username "user" -password "pass" -url "https://mycool.registry.com"`

⚠️ After script is completed, please notice that you need to run garbage collection task at your registry to clear disk space: registry garbage-collection /etc/docker/registry/config.yml
