clean_registry's Issues

Script's exit code 1?

Hi there! Thanks for the project. What's a point to set the script's exit code to 1?

        exit_status = 0
        for image in images:
            if not clean_repo(image):
                exit_status = 1

        if not self.garbage_collect():
           exit_status = 1

Or do I use it incorrectly? I suppose that in order to delete an image I must run this script twice:
firstly to remove references using

docker run --rm --volumes-from 46068a8a3483  -v /var/run/docker.sock:/var/run/docker.sock  ricardobranco/clean_registry -x 46068a8a3483 <repo>:<tag>

and then to garbage-collect the second time:

docker run --rm --volumes-from 46068a8a3483  -v /var/run/docker.sock:/var/run/docker.sock  ricardobranco/clean_registry 46068a8a3483

In both cases I get 1 exit code returned for me. Is it correct?

linkname '/bin/busybox' not found

I'm running in Docker and having this issue. The container exit with a KeyError Exception.

Docker version 19.03.5, build 633a0ea838

Remote command example

I've set up remote connection to my docker daemon and I'm able to execute commands like:

rancher@rancher1:~$ docker --tlsverify=1 -H=tcp://my_ip:2376 --tlscacert=/home/rancher/certs/ca.pem --tlscert=/home/rancher/certs/cert.pem --tlskey=/home/rancher/certs/key.pem ps

And I see containers on the remote host correctly.
But when I try to clean my registry I get this error:

docker --tlsverify=1 -H=tcp://my_ip:2376 --tlscacert=/home/rancher/certs/ca.pem --tlscert=/home/rancher/certs/cert.pem --tlskey=/home/rancher/certs/key.pem run --rm --volumes-from 46068a8a3483 -e DOCKER_HOST=https://my_ip:2376 -v /home/rancher/certs:/root/.docker ricardobranco/clean_registry 46068a8a3483 repo:tag
ERROR: HTTPSConnectionPool(host='my_ip', port=2376): Max retries exceeded with url: /v1.35/containers/46068a8a3483/json (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certific

Notice that I omit -e DOCKER_TLS_VERIFY=1, because otherwise docker shouts at me with this:

ERROR: Path to a certificate and key files must be provided through the client_config param. TLS configurations should map the Docker CLI client configurations. See https://docs.docker.com/engine/articles/https/ for API details.

How should I specify the remote's address and tls stuff to get it working?

clean_revisions not called when remove is specified?

Currently clean_revisions is only called when not specifying a remove operation. Shouldn't it be called when -x (remove) is used?

-V doesn't work

if you run clean_registry -V you don't get the version but rather the usage because a container or volume isn't found. This works better:

if args.help:
print('usage: ' + usage)
sys.exit(0)
elif args.version:
print(progname + " " + VERSION)
sys.exit(0)
elif not agrs.container_or_volume:
print('usage:" + usage)
sys.exit(1)

how to use with none-docker registry instance?

I have a local /usr/sbin/registry instance running.. (not inside docker) how do I use this to clean up? I have no container to point it at..
