# Use this script to launch Mail-in-a-Box within a docker container.
# ==================================================================
#
# Run this script from the base directory of the Mail-in-a-Box
# repository (i.e. run as 'containers/docker/run').
#
# A base image is created first. The base image installs Ubuntu
# packages and pulls in the Mail-in-a-Box source code. This is
# defined in Dockerfile at the root of this repository.
#
# A mailinabox-userdata container is started next. This container
# contains nothing but a shared volume for storing user data.
# It is segregated from the rest of the live system to make backups
# easier.
#
# The mailinabox-services container is started last. It is the
# real thing: it runs the mailinabox image. This container will
# initialize itself and will initialize the mailinabox-userdata
# volume if the volume is new.

# Build or rebuild the image.
# Rebuilds are very fast.
