registry-1.docker.io about dxf

[davedoesdev]

Hi @sadaszewski

Thanks for raising this.

Does test/module_example.py work for you on a test repo? I just tried it against one of my repos and it worked. Just trying to narrow down where the problem is.

@sadaszewski also, this works for me:

$ DXF_HOST=registry-1.docker.io dxf list-aliases davedoesdev/test
may15-readings
wup

without having to set DXF_USERNAME or DXF_PASSWORD. Does it work for you?

Note that dxf list-repos doesn't work on Docker Hub. I guess they don't want people listing every single repo on the system.

@sadaszewski did you get a chance to try the above?

[davedoesdev]

@sadaszewski any updates on the above?

[sadaszewski]

Hi David, Apologies for the hiatus. Let's forget about it for the moment, as I have decided to keep the project limited to image building and container composition, leaving image registry support out of it. Perhaps someone else will pick this story up in the future. Thank you and sorry for the trouble. Best regards,

I recently came across this and think I see what might be happening. At least in my case.

Two component repos work fine, eg. docker.io/curlimages/curl, docker.io/bitnami/python, and docker.io/circleci/openjdk but 1 component repos fail to authenticate every time, eg. docker.io/python, docker.io/openjdk and docker.io/eclipse-temurin.

I was running 7.7.2, because pip refused to install 7.7.3 because of a dependency conflict, but ultimately got both installed and both fail to work for single component repos.

I poked around some and it looks like it may be how you're setting _repo_path or how authentication itself is being processed. Please let me know how I can help.

Edit:

Ok I think I figured it out. For single component repos, like python, java, and openjdk, you need to prepend library to the API call, eg. registry-1.docker.io/python needs to be registry-1.docker.io/library/python(host=registry-1.docker.io, repo= library/python). I modified your code to this and it seemed to work:

repo_parts = repo.split("/")
if len(repo_parts) == 1:
    self._repo = "library/" + repo
    self._repo_path = ("library/" + repo + "/") if repo else ""
else:
    self._repo =  repo
    self._repo_path = (repo + "/") if repo else ""
