docker-rabbitmq-cluster's Introduction

This folder structure contains the Dockerfiles for building RabbitMQ cluster - the number of nodes are completely customizable using docker-compose docker-compose.yml file.

Structure:

There are 3 folders.

base - this is the base Dockerfile which builds on a CentOS image and installs the RabbitMQ binaries on the image
server - This builds on the base image and has the startup script for bring up a RabbitMQ server
cluster - This contains a docker-compose definition file(docker-compose.yml) for brining up the rabbitmq cluster. Use docker-compose up -d to bring up the cluster.

Running the Cluster:

Once the images are built, boot up the cluster using the docker-compose.yml configuration provided in cluster folder:

docker-compose up -d

By default 3 nodes are started up this way:

rabbit1:
  image: bijukunjummen/rabbitmq-server:3.6.5
  hostname: rabbit1
  ports:
    - "5672:5672"
    - "15672:15672"
  environment:
    - RABBITMQ_DEFAULT_USER=myuser
    - RABBITMQ_DEFAULT_PASS=mypass
rabbit2:
  image: bijukunjummen/rabbitmq-server:3.6.5
  hostname: rabbit2
  links:
    - rabbit1
  environment:
   - CLUSTERED=true
   - CLUSTER_WITH=rabbit1
   - RAM_NODE=true
  ports:
      - "5673:5672"
      - "15673:15672"

rabbit3:
  image: bijukunjummen/rabbitmq-server:3.6.5
  hostname: rabbit3
  links:
    - rabbit1
    - rabbit2
  environment:
   - CLUSTERED=true
   - CLUSTER_WITH=rabbit1
  ports:
        - "5674:5672"

if needed, additional nodes can be added to this file. If the entire cluster comes up, the management console can be accessed at http://<dockerip>:15672

and connection host should look like this: dockerip:5672,dockerip:5673,dockerip:5674
