set root-path to uvicorn

I’m trying to set root_path to uvicorn as suggested [1] using this image, but don’t see any options to pass arguments:

uvicorn main:app --root-path /api/v1

How can I do it?

@poppash On my side it does not work I am getting an error in OpenApi

Python 3.7.8 fastapi 0.63.0

Run configuration: uvicorn.run(“app:app”, host=“0.0.0.0”, port=port, reload=True)

I think the error is in the path here is console log: 127.0.0.1:54913 - "GET /api/v1/api/v1/openapi.json HTTP/1.1" 404 Not Found Here is double path: /api/v1/api/v1/

I struggled with this as well. Got it working in the end, albeit by setting root_path via the FastAPI object, e.g., app = FastAPI(root_path='/api/v1') and upgrading FastAPI.

Before upgrading it didn’t work either using the current tiangolo/uvicorn-gunicorn-fastapi-docker:python3.8 image because it still has fastapi==0.55.1 installed. Try docker container run tiangolo/uvicorn-gunicorn-fastapi:python3.8 pip freeze | grep fastapi to verify. This image was last updated 3 months ago, probably just before the release of fastapi==0.56.0 (see PR).

Extending from tiangolo/uvicorn-gunicorn-fastapi-docker:python3.8 and then pip install --upgrade fastapi==0.61.1 did the trick for me.

@tiangolo will the images be updated in the near future?
