Multistage build for python and nodejs in the same container

I need to have access to both npm and pipenv in the same container. I'm thinking the best way to accomplish this is with a multistage build.

If I do something like this:

FROM python:3.7
COPY Pipfile /app/Pipfile
RUN pip install pipenv

FROM node:8
npm install

How do I make sure that the pipenv binary is not discarded? What files do I need to copy from the previous stage so that pipenv is available in the final image?

Solution

  • multi-stage build is not required in your case. Start from base image python:3.7 and install node in it , will be the straightforward solution

    FROM python:3.7
COPY Pipfile /app/Pipfile
RUN pip install pipenv

# Using Debian, as root
RUN curl -sL https://deb.nodesource.com/setup_11.x | bash -
RUN apt-get install -y nodejs

    how do you know the image python:3.7 is debian?

    $ docker run -ti --rm python:3.7 bash
