How do I install python3 and python3-pip on an alpine based image (without using a python image)?
$ apk add --update python3.8 python3-pip
ERROR: unsatisfiable constraints:
python3-pip (missing):
required by: world[python3-pip]
python3.8 (missing):
required by: world[python3.8]
This is what I use in a Dockerfile for an alpine image:
# Install python/pip
ENV PYTHONUNBUFFERED=1
RUN apk add --update --no-cache python3 && ln -sf python3 /usr/bin/python
RUN python3 -m ensurepip
RUN pip3 install --no-cache --upgrade pip setuptools
