akka-cluster-heartbeat - akka hello world in a hard way

Trying to implement minimal akka cluster app with a simple purpose.

Dev

cd akka-cluster-heartbeat
sbt 'run cmd --option'

Tests

sbt test

If you run tests in the IntelliJ IDEA, don't forget to run multi-jvm tests manually:

sbt multi-jvm:test

Building

sbt assembly

Usage

java -jar target/scala-2.11/akka-cluster-heartbeat-assembly-*.jar COMMAND [OPTIONS]

Commands:

• node - work with cluster node
• emulator - start emulator

For options see java -jar akka-cluster-heartbeat-assembly.jar --help

Start cluster

java -jar akka-cluster-heartbeat-assembly.jar node --port 2550

Add node

java -jar akka-cluster-heartbeat-assembly.jar node --port 2551 --role stat

Remove node

Just kill the process by SIGTERM or SIGINT.

kill -INT $pid
kill $pid

or just Ctrl+C if you have an interactive run.
