   === *master-replica* - Creating a master and replica database cluster
  
positive.code: 
  Some users will need or want a DNS name to resolve to their container
  names.  The crunchy-dns container provides the following:
   * listens to a Docker URL or socket for events that would indicate
   a container is created or destroyed
   * implements the consul.io DNS server
  
negative.code: Those examples are explained below.  The examples make use of
  the local Docker volume driver and data volumes created
  by the *docker create volume* command.  There is a bug however
  that requires the container to run as privileged when in
  SELinux enforcing mode.  See https://github.com/docker/docker/issues/20859[here] for more details.  Also, see link:https://github.com/docker/docker/pull/23024[here].  When this is fixed, you will not need to specify *privileged*
  when starting the examples.
