FROM python:3.8-alpine AS compile-image
# Gevent needs gcc
RUN apk update && apk add gcc musl-dev
# Switch to a non-root user for security reasons
# This is only really needed in stage 2 however this makes the copying easier and straitforward! --user doesn't do the same thing if run as root!

# Speed hack; we install gevent FIRST because when building repeatedly (eg during dev) and only changing a1 code, we do not need to keep compiling gevent which takes forever
