This is a minimal demo application that boots an empty Akka cluster and stays idle until VM is terminated.
The application is packaged as Docker image. In order to build the image locally, run the following command in the project's top level directory:
sbt publishLocal clusterMonitor/docker:publishLocal
After the build is complete, docker images listing should contain
caltha/akka-cluster-etcd/monitor image. When invoked directly using
docker run caltha/akka-cluster-etcd/monitor, the application will complain about not being able
to connect to etcd server running at host etcd. See other example directories for different
ways of running the application in a cluster.
