how to debug an application about uvicorn-gunicorn-fastapi-docker

[tiangolo]

@Kludex implemented integrated support in the official Python VS Code extension: microsoft/vscode-python#14606

Meanwhile, you can try these snippets: microsoft/vscode-python#14247 (comment)

My workaround is to add
import uvicorn
and at the bottom of the main.py

if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=8000)

And run it as a normal python file without docker at all. In pro version of pycharm it is possible to setup docker as a remote debugger, but I don't use that feature.

thank you. I'll check out pycharm

I do all of the above but then I get the following error when hitting the endpoint.

@geekkun that does not support auto-reload though, right?

At least I had to do something like this in a file in my root folder for reload to work as well

if __name__ == "__main__":
    uvicorn.run("app.main:app", host="0.0.0.0", port=8000, reload=True)
