How to get pipenv running in docker?

Question

Im installing pipenv in my docker:

RUN pip install pipenv
RUN cd /my/app/path/ && pipenv install
RUN cd /my/app/path/ && pipenv shell

The direct answer to this question is to not use shell, but rather run:

CMD ["pipenv", "run", "python", "my/app.py"]

If you need more flexibility, you could also pipenv run sh init.sh, which would create a shell initialized with all the pipenv environment variables.

I actually prefer the approach C. Sweet mentions. If you can get away with prebuilding your virtual environment and simply copying it over (setting PIPENV_VENV_IN_PROJECT then using a nested FROM followed by COPY --from=builder-image), you don't need python nor pipenv nor pipenv dependencies in your final container. This greatly reduces the size of the final image.

Dockerfile:

WORKDIR /etc/service/
CMD ["sh", "/etc/service/init.sh"]

init.sh:

source /etc/service/my/.venv/bin/activate
python my/app.py
