Add --system to uv pip install in guide/docker under "Container from a Python Package"

[eschmidt42]

Steps to reproduce

Running on Ubuntu I followed the steps under Container from a Python Package

rye build --wheel --clean
docker build . --tag your-image-name

with the run command as described on the page as

RUN --mount=source=dist,target=/dist uv pip install --no-cache /dist/*.whl

Which I think may be missing the --system flag in uv pip install?

If I use --system it works and if if I don't it doesn't, see below 🙂 .

Expected result

docker build -f ./my_app/Dockerfile --tag my-app .
