cannot download unofficial dockerhub repos

[tpdownes]

I am trying to use this script in my own workflow. I find that it works fine for official repos such as centos:6 (etc) but not for ones in other namespaces. e.g. LIGO

thomas.downes@downes-dev:~/cvmfs-singularity-sync$ ./cvmfs-singularity-sync --docker ligo/ligo-wn:latest --rootfs /tmp/tpdownes/
Docker image to publish: ligo/ligo-wn:latest
Error getting tags using url https://registry-1.docker.io/v2/ligo/ligo-wn/tags/list

I do not believe this was always the case. It affects the bulk of the repos listed in docker_images.txt and the behavior is the same if I use the images-url argument instead.

I have also tried reverting to a version prior to glob support with the same outcome. I have even tried the cli.py file inside the singularity package. Same outcome.

Is this what it would look like if I have been blocked by Docker hub?

Now that we overhauled the guts of this script to use the local Docker daemon (having access to the full set of APIs), we should be able to do this, I think.

Adding Derek.

I tested my script against containers.ligo.org (even authenticated) successfully.

    if username is not None and token is not None:
        client.login(username=args.username, password=args.token,
                registry=args.registry)

I originally took your approach of saving the image (which is tar) and untarring it but I thought it unnecessarily expensive.

I believe this issue is resolved. We've since switched to apptainer (singularity) sandbox to generate images in #195.
