# Install docker-in-docker (dind). See https://hub.docker.com/_/docker/. The docker git repo
# currently only has 1.10 and 1.11, but it's possible to get the dockerfiles for earlier
# versions by using:
#        docker pull centurylink/dockerfile-from-image
#        alias dfimage="docker run -v /var/run/docker.sock:/var/run/docker.sock --rm centurylink/dockerfile-from-image"
#        dgimage <name of image>

# This container must be started in privileged mode.

# Instead of using docker-in-docker, we can just attach ourselves
# to the docker socket via a volume in the docker-compose:
#     - /var/run/docker.sock:/var/run/docker.sock
# This is more convenient, allowing us to build directly into our
# parent's docker build system, making the images available for
# instantiation on the parent.
