Python Debugger Should Support debugpy and ptvsd

[cpvandehey]

Expected behavior

Currently ptvsd is the only DAP supported by skaffold for python apps. Microsoft is deprecating ptvsd for debugpy -- debugpy link. debugpy has a lot of the bug fixes revolving around debugging multiprocess python applications that ptvsd does not have (the press release is here). skaffold should consider making the debug package configurable or converting over to debugpy exclusively once it gets out of beta (or even now for that matter).

In the meantime, I will be inserting the command arguments manually in order to use debugpy locally and specifying a debug port in the portForwarding section (replacing skaffold debug for now with a manual process -- e.g. "-m", "debugpy", "--listen", "0.0.0.0:5000",...).

• Skaffold version: latest
• Operating system: mac
• Contents of skaffold.yaml: n/a

Any update @briandealwis ?

@briandealwis looks like this should be closed now?

Not yet: I've added debugpy to the duct-tape images (still needs to be regenerated), but I need to fix debug to reference debugpy now.

Thank you all. Let me know how I can follow the relevant release for this.

It looks like we can rewrite gunicorn command-lines as python -m debugpy --listen :PORT -m gunicorn.app.wsgiapp.
