how to develop ?

Hi,

I like to develop within the docker container so that I use the same environment that is used later in prod.

I run: docker run -it --rm -v /c/Users/myuser/chat/api:/app -p 8090:8000 my-image-name:0.0.2 uvicorn main:app --reload

So I map using -v my local directory inside the container. When I change a file locally the reloader within docker detecs it and restarts the application. That works fine. But if I try to connect to http://localhost:8090/ I get a “The connection was reset” message in the webbrowser (firefox).

Uvicorn logs that its running on http://127.0.0.1:8000 so -p 8090:8000 should work - I thought 😃

my-image-name:0.0.2 is based on tiangolo/uvicorn-gunicorn-fastapi:python3.8-slim and basically only installs some python packages and then does a COPY /api /app I develop on Windows 10 using WSL (not WSL2).

Does anyone else had this issue ?

Thanks!

ah you don’t run it as sudo… if you run sudo docker ps you can check the port mapping.

docker run -it --rm -p 8090:8000 tiangolo/uvicorn-gunicorn-fastapi:python3.8-slim uvicorn main:app on your computer can you connect to http://localhost:8090 ?

Yes

One more thing, try to run the uvicorn with --host option uvicorn main:app --host 0.0.0.0
