Installing numpy on Docker Alpine

Question

I\'m trying to install numpy in a docker container based on Alpine 3.1. I\'m using the following Dockerfile:

FROM alpine:3.1
RUN apk add --update make cmake          


        

Answer 1

This one is about 311MB according to my docker images:

FROM python:3.6-alpine
RUN apk add g++ 
RUN pip install numpy

(Meanwhile python:3.6 is ~900MB by itself)

Have you tried NOT having gcc installed? It might be conflicting? Not sure. This one worked for me as a minimal numpy installation and wanted to share.
