I had issues getting 3.9 to work my FastAPI service,

Using a python:3.9-slim base image I needed to install a few more dependencies than before with fastapi 3.8-slim version (FastAPI 0.55.1)

...
RUN apt-get update && apt-get install -y build-essential=12.6 \ 
&& pip install --no-cache-dir uvloop==0.14.0 httptools==0.1.1 uvicorn==0.13.0 gunicorn==20.0.4 fastapi==0.62.0 \
...

I needed to install build-essential, uvloop and httptools, without these FastAPI api would not startup.
Not sure why, yet this did the trick for me

Please

I have built uvicorn-gunicorn-fastapi images for python3.9 using these uvicorn-gunicorn images as the base.

Feel free to use the images until @tiangolo merge either #64 or #52 at uvicorn-gunicorn-docker repository.

DockerHub links and sources are available in my repo.

Current images are based on PR #67.

So, are we skipping Python 3.9 and jumping straight to 3.10 then?
