Build python's gevent in outer Docker image

Question

This dockerfile will obviously not work:

FROM python:3.7.0-alpine

RUN pip install gevent

since there is no compiler in alpine.

Is it possible to install it in a different docker image and then copy it to my image?

In other words, can i achieve that by replacing <???> with something?

FROM python:3.7.0-streach as base

RUN pip install gevent

FROM python:3.7.0-alpine

COPY --from=base <???>

Answer 1

For those finding this a year later, this should work:

FROM python:3.7.0-stretch as base

RUN apk add build-base
RUN mkdir /install
RUN pip install --install-option="--prefix=/install" gevent

FROM python:3.7.0-alpine

COPY --from=base /install /usr/local
