potiuk opened a new pull request #14783:
URL: https://github.com/apache/airflow/pull/14783
The base python image is only updated when manually triggered and
in case of checking for upgraded dependencies in master build.
While automated upgrade to latest Python image is good for
security, it can cause a number of problems when run automatically
in the CI:
* cache invalidation - thus longer builds
* sudden test failures
This happened in the past already quite a number of times so it
is time to switch to a bit different mode. Python images will only
be automatically upgraded in those cases:
1) When Master CI build is run in scheduled nightly build - to check
that tests still pass for latest version of the image
2) When manually refreshed with --force-pull-base-python-image
3) When DockerHub official images (from tags) are built.
The procedure to refresh the images manually in our CI has been
added to the documentation.
