Question: Why does python3.8-slim image not come with fastapi pre-installed? about uvicorn-gunicorn-fastapi-docker

[lazarillo]

I think no one may have responded because your question is not clear.

Are you really asking why python3.8-slim does not have FastAPI on it? FastAPI is a specific web framework. While it is a great framework, I would suspect that (a) 99.9% of Python projects do not use it, and (b) it is quite large. It is not something that the 99.9% of other projects would want bulking up their work.

Or, do you mean to ask, "why is there no 'slim' version of fastapi"? My guess is that no one has had the time or energy to create it. I suspect if you put together a good Dockerfile to do this, it would be accepted into the project.

Just like 99.9% of python projects don't use FastAPI, so are uvicorn and gunicorn, which are installed in the image. So, my question was to ask about the absence of FastAPI, when it's dependencies are installed in the image.

EDIT: Or should I be asking about the presence of uvicorn and gunicorn, when 99.9% of projects don't actually use them.

I assume you solved it, thanks for closing the issue 👍

Anyway, I checked, and FastAPI seems to be included as expected 🤷
