#
#  This playbook creates a kubernetes cluster on a single system using the
#  example in the Red Hat documentation.  The cluster contains a database
#  and a webserver pod with data from the database to present a webpage that
#  says "Red Hat Rocks!"
#
#  Execution Steps:
#    1. Subscribe to RedHat if running RHEL Atomic Host
#    2. Create an insecure private registry
#    3. Copy over the mariadb and apache webserver Dockerfile and supporting
#       files, build the docker image, tag the image, then push to the private
#       registry.
#    4. Setup and start the kubernetes pods
#    5. Setup and start the mariadb and webserver pods
#    6. Verify that the pods are running and that the mariadb and webserver
#       can communicate through the kubernetes services
