# This script installs and starts Docker. This currently supports
# Ubuntu and Redhat distributions. It does the following:
# 1. Adds the appropriate repository that has Docker
# 2. Installs Docker from that repository
# 3. Starts the Docker service
# 4. Adds the current user to the docker group
#
# After this runs, the user will still need to relogin to detect
# membership in the docker group.

# This can get more detailed if there are specific steps
# for specific versions, but at the moment the distribution
# is all we need.
