- Modified PythonAppResourceBuilderExtensions to generate Dockerfiles for all Python apps - Split Dockerfile generation into two methods: GenerateUvDockerfile and GenerateFallbackDockerfile - Fallback Dockerfiles detect requirements.txt and run pip install if present - Uses same runtime image (python:X.Y-slim-bookworm) as UV workflow for consistency - Updated PythonVersionDetector to accept nullable VirtualEnvironment parameter - Added comprehensive tests for fallback Dockerfile generation Co-authored-by: davidfowl <95136+davidfowl@users.noreply.github.com>

There was a problem hiding this comment.
It feels weird to the discard the value of the TryGet here. It seems like we could still set the fallback Python version even if we did include the if-statement.

I think the logic that is here is what we want. Including an if on the TryGet would make the logic harder to read/follow IMO. The TryGet will output a null annotation if one isn't found, so doing the null checks seems like the easiest way.

Backport of #12627 to release/13.0
/cc @eerhardt @copilot
Customer Impact
Previously, Dockerfiles were only generated for Python apps using UV. Non-UV Python apps had no automatic containerization support.
Testing
Added new automated tests. Manually tested the
playground\python\instrumented_scriptapp produces a docker image successfully.Risk
Only affects Python apps, and only if they aren't using UV.
Regression?
No
