potiuk opened a new pull request #15320:
URL: https://github.com/apache/airflow/pull/15320
After PROD images were added, some of the flags had two meanings
These behaved differently in PROD image and CI image and were the
source of confusion especially when start-airflow command was used.
For PROD image, the image can be customized during image building,
and packages could be installed from .whl or .sdist packages
available in `docker-context-files`. This
is used at CI and dockerhub building time to produce image built
packages that were prepared using local sources.
The CI image is always built from local sources but airflow can
be removed and re-installed at runtime from pypi.
Both airflow and provider packages can be installed
from .whl or .sdist packages available in dist folder. This is
used in CI to test current provider packages with older
Airflow released (2.0.0) and to test provider packages locally.
After the change we have two sets of flags/variables:
PROD image (building image):
* install-airflow-version, install-airflow-reference,
install-from-docker-context-files
CI image (runtime):
* use-airflow-version, use-packages-from-dist
That should avoid confusion and failures of commands such as
`start-airflow` that is used to test provider packages and
airflow itself.
