Question about --chown=python:python in standalone.Dockerfile

[MiquellaPrime]

Hi! Thanks for the uv-docker-example repo — it’s very helpful.

I have a question about this line in the standalone.Dockerfile:

COPY --from=builder --chown=python:python /python /python

In the final stage, only the nonroot user is created, and there is no python user or group. Because of that, --chown=python:python doesn’t seem to apply — the files remain owned by root.

Is this intentional, or should the example use nonroot:nonroot here?
Or maybe the python user was meant to be created as well?

Just want to understand the intended behavior. Thanks!
