Apache Airflow "latest" image is still Python 3.8 in Airflow 2.8.0

[potiuk]

Body

Despite what is documented in Changelog and what we agreed in the lazy consensus , the default docker imagest (latest/latest-slim) are still pointing to Python 3.8.

The changelog should be corrected and that move should happen in Airflow 2.9

Looks strange.. It looks like the code is there and fixed .... puzzled a bit... But I will find out.

Good catch! but yeah, it's very strange. Based in the CI log, it should be ok:

Replacing latest images with links to the newly created images.
Creating apache/airflow:latest-python3.11 alias for apache/airflow:2.8.0-python3.11
Running command: <regctl image copy apache/airflow:2.8.0-python3.11 apache/airflow:latest-python3.11>
  
  Working directory /home/runner/actions-runner/_work/airflow/airflow
  
  
  regctl image copy --force-recursive --digest-tags apache/airflow:2.8.0-python3.11 apache/airflow:latest-python3.11

  regctl image copy --force-recursive --digest-tags apache/airflow:2.8.0 apache/airflow:latest

I checked the sha256 of the images we released one month ago to ensure that it is not a new issue, but it looks like we had the same issue with the RC images.

Ah... I know .. my mistake. If you look here - it only changese at which python version the "2.8.0" alias points to latest one. There is no python used in this if, so the only thing it change is when latest becomes aliased to2.8.0.

            if python == ALLOWED_PYTHON_MAJOR_MINOR_VERSIONS[-1]:
                # only tag latest "default" image when we build the latest allowed python version
                if slim_images:
                    alias_image(
                        f"{dockerhub_repo}:slim-{airflow_version}",
                        f"{dockerhub_repo}:slim-latest",
                    )
                else:
                    alias_image(
                        f"{dockerhub_repo}:{airflow_version}",
                        f"{dockerhub_repo}:latest",
                    )

But what should be changed is the line before that:

            if python == DEFAULT_PYTHON_MAJOR_MINOR_VERSION:
                alias_image(image_name, f"{dockerhub_repo}:{airflow_version}")

(and similar one in slim image) - > because THERE the "airflow:2.8.0-python3.8" gets the airflow:2.8.0 alias - which what it was about.

I will announce it at devlist that we are delaying it and remove the log in dockerfile changelog.
