Docker Distribution (Registry) UI

Web UI for Private Docker Distribution (Registry).

Features

• Browse Registry (Semantic React UI)
• Delete images from Registry
• more coming..

Requirements

• Registry 2.6+ (should be ok with > 2.3 but untested)
• CLI access to host where Registry is running (run garbage-collect command)

Prebuilt docker image

Run somewhere on Docker enabled host:

$ docker pull dalee/hitman
$ docker run \
    -e MACARON_ENV=production \
    -e REGISTRY_URL=https://registry.example.com:5000/ \
    dalee/hitman

Put command to your favourite scheduler (cron, ci, etc..)

$ docker exec -it docker.registry \
    bin/registry garbage-collect /etc/docker/registry/config.yml

Where docker.registry is name of container running Docker Registry.

Common pitfalls

• There is no auth, so, restrict access to UI via frontend (NGINX deny/allow for example)
• Multiple tags could point to single digest (you can have latest and v1.0.1 tags, but they actually single image, so be careful)
• Tag deletion will not free you hard drive space until garbage-collect command is issued
• Depending on storage driver, you may have to manually delete empty repositories (ui will show you hint)
