Creates a 3 node RabbitMQ cluster with a HAProxy acting as a load balancer.
You need to build the HAProxy image first, just run:
$ docker build -t roofimon/haproxy-rabbitmq-cluster:2.3 .Now run the docker compose file:
$ docker-compose up -dcheck if the containers are running:
$ docker psCreate the cluster by running:
$ docker exec -ti rabbitmq-node-2 bash -c "rabbitmqctl stop_app"
$ docker exec -ti rabbitmq-node-2 bash -c "rabbitmqctl join_cluster rabbit@rabbitmq-node-1"
$ docker exec -ti rabbitmq-node-2 bash -c "rabbitmqctl start_app"
$ docker exec -ti rabbitmq-node-3 bash -c "rabbitmqctl stop_app"
$ docker exec -ti rabbitmq-node-3 bash -c "rabbitmqctl join_cluster rabbit@rabbitmq-node-1"
$ docker exec -ti rabbitmq-node-3 bash -c "rabbitmqctl start_app"Check the cluster status:
$ docker exec -ti rabbitmq-node-1 bash -c "rabbitmqctl cluster_status"Options for more resilience
Declares a policy which matches the queues whose names begin with "two." are mirrored to any two nodes in the cluster, with automatic synchronisation:
$ docker exec -ti rabbitmq-node-3 bash -c 'rabbitmqctl set_policy ha-two "^two\." "{\"ha-mode\":\"exactly\",\"ha-params\":2,\"ha-sync-mode\":\"automatic\"}"'
Declares a policy which matches the queues whose names begin with "test_" and configures mirroring to all nodes in the cluster:
$ docker exec -ti rabbitmq-node-3 bash -c 'rabbitmqctl set_policy ha-all "^test\_" "{\"ha-mode\":\"all\"}"'Access HAProxy statistics report at
