Installing netifaces in a container | Working receipe for alpine

[ChristianTremblay]

Had some trouble pip installing netifaces inside a container. Got it working with this dockerfile

FROM python:3.7-alpine
RUN apk add build-base python3-dev linux-headers
RUN pip install --upgrade pip
RUN pip install pipenv
RUN pip install netifaces
