An example akka-cluster project with Docker support. See the blog post. Uses SBT Native Packager.
In SBT, run docker/publishLocal to create a local docker container.
To run the cluster, run docker-compose -f docker-compose-akka-cluster.yml up -d. 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 and watch the cluster nodes respond.
