potiuk opened a new pull request, #33879:
URL: https://github.com/apache/airflow/pull/33879
This PR aims to prevent a misuse of _PIP_ADDITIONAL_REQUIREMENTS by mistakes
that our users often make without realising the consequences.
1) The _PIP_ADDITIONAL_REQUIREMENTS should only be used for quick
iterations and testing, they should never be used in anything
resembling production environment. This PR will give maximum
10 minutes of life for a container that has the environment
variable set. Should be enough for testing but unusable for
production.
2) When installing the _PIP_ADDITIONAL_REQUIREMENTS we additionally
install airflow version corresponding to the airflow version
already installed in the image. This prevents accidental
downgrades or upgrades of airflow by installing dependencies that
are not compatible with given airflow version
3) After installing the depdencies with _PIP_ADDITIONAL_REQUIREMENTS
we run `pip check` to make sure that newly installed requirements
are not in conflict with some other requirements installed earlier.
