Thank you for the thorough explanation. And thanks to Taavi who just added a python-bookworm image (maybe inspired by my question 😉).

The link to the production images is especially useful when I try to figure out what the different images do. A bit of feedback for the registry that would have helped me and may help in the future:

1. Add links from images to the Docker templates that were used to create them.

2. Mark images that are deprecated so you know to not use them.

Take care,

Hi Sebastian,

We have dropped the "wikimedia-" prefix for base distribution images, you can safely use the "bookworm" image as a base image.

Regarding python images, the python-build-* images are for building wheels that can be copied over to a runtime image. The python3-bullseye and python3-buster images are runtime images. The python3 image (without suffix) is deprecated.  We do not yet produce a python3-bookworm image, although I think that can be arranged pretty easily.

In the meantime, using the bookworm image and using blubber's apt directive to install python3, python3-pip, and python3-setuptools will give you the same thing.

All these images are base and production images images built through docker-pkg following the "generations" outlined in our Kubernetes image building policy.

Hope this helps,

I'm updating some blubberised repos that a colleague of mine created some time ago and I'm not sure what base images from the Docker registry are the best to use.

For instance, one repo uses docker-registry.wikimedia.org/wikimedia-buster as base image in .pipeline/blubber.yaml. I thought I'd update to Bookworm as the newest stable Debian release, but there is no image "wikimedia-bookworm", only "bookworm". I'd like to know what's different in the the ones with the wikimedia- prefix.

There are also several different ones for Python, e.g. "python3", "python3-buster" and "python3-build-buster".

Is there documentation somewhere or links to repos where I can see what Docker or Blubber files were used to create them?
