# Ryu SDN Container
# 
# Loosely based on https://registry.hub.docker.com/u/osrg/ryu/dockerfile/
# and http://ewen.mcneill.gen.nz/blog/entry/2014-08-31-ryu-on-ubuntu-14-04/
#
# Built based on separate Ryu build container, to increase the amount of 
# useful caching that we get; see "two Dockerfile" approach here:
#
# http://jpetazzo.github.io/2013/12/01/docker-python-pip-requirements/
#
# (in particular there is no caching beyond "ADD", because it could change
# on any run.)
#
# For syntax, see: http://docs.docker.com/reference/builder/
#
# VERSION 0.0.1
