Akka Cookbook

How to do it...

1. Bring the required dependencies to begin with.
2. Edit the build.sbt file and add the Akka cluster tools dependency as follows:

3. Create a new file named application-cluster-autodown-1.conf in the src/main/resources directory with the following contents:

        akka {          actor {            provider = "akka.cluster.ClusterActorRefProvider"          }          remote {            log-remote-lifecycle-events = off            enabled-transports = ["akka.remote.netty.tcp"]            netty.tcp {              hostname = "127.0.0.1"              port = 2552            }          }          cluster {            seed-nodes = [              "akka.tcp://ClusterSystem@127.0.0.1:2552", "akka.tcp://ClusterSystem@127.0.0.1:2553" ...
