. How to run uvicorn inside Dockerfile?

[scheung38]

Description

How can run uvicorn and -e etc inside Dockerfile in Win 10:

docker run -e WORKER_PER_CORE='3' -e PORT="5000"

inside Dockerfile

FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7
:
ENTRYPOINT[]
CMD[]

so that

docker run -p 5000:5000 my-api

encapsulates these environment variables in CLI command?

Looked at these examples but dont show:

"Uvicorn documentation indicates you have to run uvicorn from the command line for the debugging/auto-reloading feature to work. It can’t be run programmatically either." ???

inside Dockerfile

FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7
:
ENTRYPOINT[]
CMD[]

Note that you are overriding ENTRYPOINT and CMD with an empty command! Which comes from CMD ["/start.sh"] => start.sh which actually runs Gunicorn with Uvicorn workers (the recommended way to run Uvicorn in production). Try removing ENTRYPOINT and CMD from your Dockerfile.

Anyway, if you still want to override that, set the CMD to be something like uvicorn --reload your_app.app:app: CMD ["uvicorn", "--reload", "your_app.app:app"].

Yep, exactly, as @HacKanCuBa says.

You don't need to specify a custom command or entrypoint in your Dockerfile.
