• erlang: It contains the Dockerfile to build erlang-alpine that will be used by RabbitMQ
• server: It contains the Dockerfile to build RabbitMQ server. It used rabbitmq_base as base image
• cluster: It contains docker-compose file to launch the cluster of RabbitMQ nodes

  docker pull lucifer8591/rabbitmq-server:3.7.17
  docker run  lucifer8591/rabbitmq-server:3.7.17

Visit the http://:15672 to view management console

Management UI

Manage UI is accssible using localhost:15672 or http://:15672 i.e in my case it is http://192.168.224.1:15672. You can find docker ip using docker network inspect network_name

Management Dashboard

Compose Logs

To view logs when RabbitMQ is launched as screenshot

docker-compose logs -f 
// or for specific node logs
docker-compose logs -f rabbit1

Future TODO's

• HA proxy
• Swarm deployment
• Custom logging

Happy Coding :grinning:
