akka-docker-cluster-example
An example akka-cluster project with docker support. See the blog post. Uses SBT Native Packager.
How to Run
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. (my observation: this doesn't seem to work)
Or run each container separately with:
docker run --rm -it --name seed nmurthy/clustering:0.3
docker run --rm -it --name member1 --link seed:seed nmurthy/clustering:0.3
docker run --rm -it --name member2 --link seed:seed nmurthy/clustering:0.3
...
docker run --rm -it --name memberN --link seed:seed nmurthy/clustering:0.3
While running, try opening a new terminal and (from the same directory) try things like docker-compose down seed and watch the cluster nodes respond.
Enable JMX monitoring with:
./target/universal/stage/bin/clustering \
-Dcom.sun.management.jmxremote.port=9999
-Dcom.sun.management.jmxremote.authenticate=false \
-Dcom.sun.management.jmxremote.ssl=false
