docker swarm token discovery service


$ swarm create
{token_id} --> unique id to identify the swarm cluster

$ swarm join token://{token_id} --addr=node_ip:port
--> add a docker node to the swarm cluster by its ip:port

[Q] where is the token service for storing the cluster id and member nodes' addresses ?

--> for the time being,

https://discovery-stage.hub.docker.com
