add Dockerfile

[eric-s-s]

It might be good to add an opinionated dockerfile. something like from: https://docs.astral.sh/uv/guides/integration/docker/#installing-uv

ARG UV_VERSION=
ARG PYTHON_VERSION=
ARG BUILD_WORKDIR=/build
ARG APP_WORKDIR=/app

FROM ghcr.io/astral-sh/uv:${UV_VERSION} AS uv-stage

FROM dev-image AS build-stage
ARG BUILD_WORKDIR

COPY --from=uv-stage /uv /uvx /bin/
WORKDIR=${BUILD_WORKDIR}
COPY . . 
RUN uv python install
RUN uv sync --locked --no-dev
RUN uv pip freeze > requirements.txt
RUN uv build

FROM dev-image AS install-stage

ARG BUILD_WORKDIR
ARG APP_WORKDIR

WORKDIR=${APP_WORKDIR}
COPY --from=build-stage ${BUILD_WORKDIR}/build .
COPY --from=build-stage ${BUILD_WORKDIR}/requirments.txt .

RUN venv --upgrade-deps venv
RUN source venv/activate
RUN pip install -r requirements.txt
RUN pip install dist/*.whl

FROM prod-image AS run-stage

ARG APP_WORKDIR
ARG APP_VENV
WORKDIR=${APP_WORKDIR}

COPY --from=install-stage ${APP_WORKDIR}/venv .

RUN export PATH="${APP_WORKDIR}/venv:$PATH"

more to come. I forget some syntax stuff here. I'll have to experiment. Also, I think that this requires some stuff from https://docs.astral.sh/uv/guides/integration/docker/#optimizations. I'll need to test this and make sure that it actually works, but that is hard from windows machine. maybe I'll need to install WSL finally
