Ejabberd cluster with docker compose

This example uses dnsdocker to discover other nodes and setup a multi-master cluster.

Build the ejabberd cluster image:

git clone https://github.com/rroemhild/docker-ejabberd.git
cd docker-ejabberd/examples/docker-compose-cluster
docker-compose build

Start dnsdocker and the first ejabberd node:

docker-compose up -d

Wait until the first ejabberd node is up and running docker-compose logs ejabberd, then add some ejabberd nodes to the cluster:

docker-compose scale ejabberd=4
