      MongoDB database service, without persistent storage. For more information
      about using this template, including OpenShift considerations, see

      This template provides a standalone MongoDB server with a database
      created.  The database is not stored on persistent storage, so any restart
      of the service will result in all data being lost.  The database name,
      username, and password are chosen via parameters when provisioning this
      service.
