An example akka-cluster project with docker support. See the blog post. Uses SBT Native Packager.
In SBT, just run docker:publishLocal to create a local docker container.
To run the cluster, run docker-compose up. This will create 3 nodes, a seed and two regular members, called seed, c1, and c2 respectively.
While running, try opening a new terminal and (from the same directory) try things like docker-compose stop seed or docker network disconnect akka-sample-cluster-docker-compose-scala_default akka-sample-cluster-docker-compose-scala_seed_1 and watch the cluster nodes respond.
