RABBITMQ_ERLANG_COOKIE needs to be consistent and content is arbitrary (required for cluster synchronization)
Join the cluster
node1
docker exec -it rq-node1 sh
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app
node2
docker exec -it rq-node2 sh
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@rq-node1
rabbitmqctl start_app
node3
docker exec -it rq-node3 sh
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@rq-node1
rabbitmqctl start_app
rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'
Check cluster status
Enter the container and execute the following command
rabbitmqctl cluster_status
