Hello, Since Docker Swarm takes the burden of maintaining dedicated service discovery registry off our shoulders, we're interested in a some sort of solution for AKKA cluster that let us avoid adopting yet another software component consul / etcd). At least we'd like smth to compare with consul/etc based solution.
