Alpine sucks for Docker

Python

janhapke.com: alpine linux sucks for hosting docker containers.

node immediately exited with a Segmentation Fault.
this is happening because Alpine doesn’t use GlibC but rather uses Musl so a lot of things need recompiling – switching to a glibc based Alpine will do the trick.

Alpine also sucks for Python: bugs.alpineLinux.org. wcfNote: use ubuntu instead as base.

Ruby

__vfprintf_chk: symbol not found. "therubyracer" does not support Alpine yet. Solution: switch to ruby:2.3.1-slim.
