Quart is pretty much "async flask". So you would do it exactly the same as you do for a flask app. ie a recipe like this should work just fine https://www.digitalocean.com/community/tutorials/how-to-build-and-deploy-a-flask-application-using-docker-on-ubuntu-20-04 https://www.digitalocean.com/community/tutorials/how-to-buil... That said I've not done it myself (yet). It's literally something I'm doing this week. Edit to add: Here's a template that looks promising actually https://github.com/cellerich/docker-quart https://github.com/cellerich/docker-quart

  I had a project which was making API calls that could take 90 seconds to generate a response from external services. My flask API was obviously blocked and when I started letting other users on I fixed the bottleneck by updating (I think) 3-5 lines of code and adding an asyncio loop. From my limited use it does seem like a drop in replacement for 'async flask'

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.

I use uvicorn and it works well. You probably will want an ingress layer in front of that, which is where nginx, haproxy, or envoy would come in.
