  +Lagoon RabbitMQ Dockerfile with management plugin installed, based on the official rabbitmq:3-management image at [docker-hub](https://hub.docker.com/_/rabbitmq).

  By default the RabbitMQ broker is started as single node. If you want to start a cluster, you need to use the [`rabbitmq-cluster`](https://github.com/amazeeio/lagoon/blob/master/images/rabbitmq-cluster/Dockerfile) Docker image, based on `rabbitmq` image plus the `rabbitmq_peer_discovery_k8s` plugin.
