Incompatibility between uvicorn and python images above 3.10 #1030
Description
Activity
Besides the python versions there aren't many differences between them. I am unable to reproduce any problem of uvicorn not being in the path (and the same result for python:3.12.10-alpine3.20 and python:3.13.3-alpine3.20):
$ docker run -it --rm python:3.11.12-alpine3.20 sh

I am using the image python python3.10.17-alpine3.20, however this notification has some CVEs. When I try to update it to any python image, either python3.11.12-alpine3.20, python3.12.10-alphine3.20 or python3.13.3-alpine3.20 I get the following error on pod start:
Error: failed to create containerd task: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "uvicorn": executable file not found in $PATH: unknownUvicorn version being used is 0.34.1. Is there some known incompatibility between uvicorn and any of those docker images? If so what image could I use that fixes the CVEs and is compatible with uvicorn?
Thank you
