How do I get python2.7 and 3.7 both installed in an alpine docker image

Question

I am trying to figure out a way that I can install both python2.7 and 3.7 in a lightweight alpine docker image.

Currently I am using the

FROM python:3.7-alpine3.9

Base image but would like to know how to get python2 installed as well.

Answer 1

Use something like:

RUN apk add --no-cache python2

This will install the latest version of Python 2 as python2 or python2.7. Python 3.7.3 will still be available using python3, or simply python.
