+Podemos ver los nodos activos:
+  # docker node ls
+  ID                           HOSTNAME  STATUS  AVAILABILITY  MANAGER STATUS
+  obtavwk9ypnpq20ubd54gt7me *  swarm1    Ready   Active        Leader
+El * indica que actualmente estamos conectados a ese nodo
+Desde el manager, sacamos el token para unir a los otros:
+  # docker swarm join-token worker
+  To add a worker to this swarm, run the following command:
+    docker swarm join \
+    --token SWMTKN-1-5wvvfc5qpmk4avbqzv0iw1st0qxtwb15ut0phwyjgmv2iw65t7-akxww3rmtsimaihqokcgmwu7a \
+.19.0.101:2377
+Lanzamos ese comando en los otros dos nodos y vemos que se han unido:
+<code>
+# docker node ls

+====== Crear un servicio ======
+https://docs.docker.com/engine/swarm/swarm-tutorial/deploy-service/
+  # docker service create --replicas 1 --name helloworld alpine ping docker.com
+  ny109vvho4z1f63lo9f2bbsb4
+  # docker service ls
+  ID            NAME        MODE        REPLICAS  IMAGE

+Ahora miramos el servicio
