# Install the packages necessary to run docker.

#

# $ensure: must be one of present or absent.

# Default: present

#

# $use_docker_repo: if true (the default), use docker.com's repository as

#   the source for the docker packages. For Debian this is currently the better

#   option as the version of docker in the Debian official repository is old

#   and docker changes frequently.

#

#   Note that the name of the package in the official Debian repository is

#   "docker.io" to avoid conflicting with an existing package that already

#   has the name "docker". The name of the package from docker.com is

#   "docker-engine".

# Default: true

# https://apt.dockerproject.org/repo
