Pin versions?

[slhck]

Would it make sense to pin the version of at least FastAPI (potentially the Uvicorn and Gunicorn as well) such that the images create reproducible builds?

I've ran into this often, where I define a specific version of this image (e.g. python3.7-2019-12-11), but whenever I build it, it just pulls the latest version of FastAPI, whatever that is at the time of building (due to RUN pip install fastapi). This may lead to inconsistencies between local versions (which I can specify in requirements.txt) and Docker builds.

You could pin the fastapi version in your own Dockerfile or you could remove the pip install fastapi and instead use your own requirements.txt file.
