dockerclean

Tools for cleaning up image tags in docker registry.

Docker container

Using docker container is more flexible to send request.

List images

$ docker run --rm drkaka/dockerclean -l 127.0.0.1:5000 list
repositories:
	drkaka/alpine

List tags of an image

$ docker run --rm drkaka/dockerclean -l 127.0.0.1:5000 tags --image drkaka/alpine
Tags for drkaka/alpine:
	3.5	3.6	latest

Delete a tag of an image

$ docker run --rm drkaka/dockerclean -l 127.0.0.1:5000 delete --image drkaka/alpine --tag latest
Please run "docker exec -it registry /bin/registry garbage-collect  /etc/docker/registry/config.yml" to free space.

If a tag is successfully deleted, the upper information will show to remind users to do Garbage collection. If some issues occur, like re-pushing to the deleted tag but can't pull back, try to restart the registry.

Keep certain number of tags

$ docker run --rm drkaka/dockerclean -l 127.0.0.1:5000 keep --image drkaka/alpine --number 5

This will delete the older and keep the latest number of tags.
