The `services` role is used to discover [Swarm services](https://docs.docker.com/engine/swarm/key-concepts/#services-and-tasks). The `services` role discovers all [Swarm services](https://docs.docker.com/engine/swarm/key-concepts/#services-and-tasks)

single target is generated. If a service has no published ports, a target per
