# To build the image:
# sudo docker.io build -t box .

# Run your container.
#  -i -t: creates an interactive console so you can poke around (CTRL+D will terminate the container)
#  -p ...: Maps container ports to host ports so that the host begins acting as a Mail-in-a-Box.
# sudo docker.io run -i -t -p 22 -p 25:25 -p 53:53/udp -p 443:443 -p 587:587 -p 993:993 box

# We need a better starting image than docker's ubuntu image because that
# base image doesn't provide enough to run most Ubuntu services. See
# http://phusion.github.io/baseimage-docker/ for an explanation. They
# provide a better image, but their latest is for an earlier Ubuntu 
# version. When they get to Ubuntu 14.04 we'll want to use:
#
# FROM phusion/baseimage:<version-based-on-14.04>
#
# Until then, use an upgraded image provided by @pjz, based on his
# PR: https://github.com/phusion/baseimage-docker/pull/64

FROM pjzz/phusion-baseimage:0.9.10
	# based originally on ubuntu:14.04
