RabbitMQ Cluster

Docker images to run RabbitMQ cluster. It uses RabbitMQ 3.7.17 for deploying set of 3 nodes rabbit1, rabbit2, rabbit3. Number of nodes are configurable.

Resources

There are 3 folders.

• base : It contains the Dockerfile to download and build rabbitmq base image
• 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

Usage

For running RabbitMQ Single node follow below steps

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

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

NOTE: guest user will not be able to login to management ui as it supports only localhost

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 😀
