When a requirements.txt file is available
(but no pyproject.toml):

  $ uv venv

... will create the corresponding .venv directory.

When a different python version is specified in `.python-version`
then installed as base, the corresponding python version will
be downloaded automatically.

After this, install the dependencies with:

  $ uv add -r requirements.txt

This will install the dependencies and
update `pyproject.toml` and `uv.lock`.

If you only want to install the dependencies in
requirements.txt, then run:

  $ uv pip install -r requirements.txt

---

And inside the projects Dockerfile:

To bake uv binaries into the docker image:

  $ COPY --from=ghcr.io/astral-sh/uv:latest /uv /uvx /bin/

During deployment, do load exact python packages verions
from `uv.lock`. This ensures compatability with the dev
environment:

  $ RUN uv sync --locked

Activate the newly installed env:

  $ RUN . .venv/bin/activate

Finally, change the entrypoint to:

  ENTRYPOINT["uv", "run", ...]
