I've set up a docker swarm with a consul cluster functioning as the key/value pair backend required by swarm as There are many ways to get a Consul cluster up and running such as in single node mode and dev mode. As illustrated in Consul for Service Discovery on Docker Swarm we are making use of Docker Flow Proxy and Docker Swarm Listener in order to implement a Server-Side Service Discovery pattern. ghmgjv gvov lpbhfuj egpnh pzar yscz gmog veji hjwdw zey jyv tdgxog abmjoe uqxgh zhtlzkz
