`python -m src.app.api` fails to run

[leplatrem]

Since src.app.api has a main, we should be able to run the app locally...

$ JIRA_USERNAME=foo JIRA_API_KEY=bar BUGZILLA_API_KEY=bz PORT=8000 poetry run python -m src.app.api

Traceback (most recent call last):

    sock.bind((self.host, self.port))
TypeError: an integer is required (got type str)

It looks like environment.py does not have the right types.

I also tried to run the app locally through Gunicorn.

$ poetry run gunicorn -k uvicorn.workers.UvicornWorker -c bin/gunicorn_conf.py src.app.api:app
...
  File "/Users/mathieu/Library/Caches/pypoetry/virtualenvs/jira-bugzilla-integration-fgdRkTUv-py3.9/lib/python3.9/site-packages/gunicorn/workers/workertmp.py", line 22, in __init__
    raise RuntimeError("%s doesn't exist. Can't create workertmp." % fdir)
RuntimeError: /dev/shm doesn't exist. Can't create workertmp.

After a quick fix in gunicorn_conf.py to remove the hard-coded value, I could get Gunicorn to work locally:

$ JIRA_USERNAME=foo JIRA_API_KEY=bar BUGZILLA_API_KEY=bz WORKER_TMP_DIR=/tmp/ poetry run gunicorn -k uvicorn.workers.UvicornWorker -c bin/gunicorn_conf.py src.app.api:app
..

So, should we keep if __name__ == "__main__" block in src/app/api.py and its related settings in src/environment.py?
