# This file lets Mail-in-a-Box run inside of Docker (https://docker.io),

|
# a virtualization/containerization manager.
|
|
#
|
|
# Run:
|
|
# $ containers/docker/run.sh
|
|
# to build the image, launch a storage container, and launch a Mail-in-a-Box
|
|
# container.

# 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

# Docker has a beautiful way to cache images after each step. The next few
|
|
# steps of installing system packages are very intensive, so we take care
|
|
# of them early and let docker cache the image after that, before doing
|
|
# any Mail-in-a-Box specific system configuration. That makes rebuilds
|
|
# of the image extremely fast.
|
|
|
|
# Update system packages.
