twisted is pretty handy for WSGI apps. You don't need to use twisted's other features (async/event framework) to just setup a reactor and serve flask, so just add twisted to your requirements.txt and then make the entry point `python3 my_server_bootstrap.py` for the server. If you want features in front of it from nginx/haproxy I would use those as a second layer with a docker compose file or something.
