Products

• VMware RabbitMQ

Issue/Introduction

This guide will show you how to use the docker to set up the Rabbitmq cluster with 3 nodes.

Resolution

• Create the network in docker

 

docker network create demo

 

 

• Create 3 rabbitmq nodes

 

docker run -d --name node1 --hostname node1 -p 5671:5672 -p 15671:15672 -e RABBITMQ_ERLANG_COOKIE=rabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=password --network demo rabbitmq:management

 

docker run -d --name node2 --hostname node2 -p 5672:5672 -p 15672:15672 -e RABBITMQ_ERLANG_COOKIE=rabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=password --network demo rabbitmq:management

 

docker run -d --name node3 --hostname node3 -p 5673:5672 -p 15673:15672 -e RABBITMQ_ERLANG_COOKIE=rabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=password --network demo rabbitmq:management

 

 

• Go to the rabbitmq node2 and join the cluster

 

docker exec -it node2 bash

rabbitmqctl stop_app

rabbitmqctl reset

rabbitmqctl join_cluster rabbit@node1

rabbitmqctl start_app

 

• Go to the rabbitmq node3 and perform the same steps.

docker exec -it node3 bash

rabbitmqctl stop_app

rabbitmqctl reset

rabbitmqctl join_cluster rabbit@node1

rabbitmqctl start_app

 

• Check the cluster status

rabbitmqctl cluster_status
