      # The "service" stanza instructs Nomad to register this task as a service
      # in the service discovery engine, which is currently Consul. This will
      # make the service addressable after Nomad has placed it on a host and
      # port.
      #
      # For more information and examples on the "service" stanza, please see
      # the online documentation at:
