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 -dto 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 -dBy default 3 nodes are started up this way:
rabbit1:
image: bijukunjummen/rabbitmq-server:3.7.0
hostname: rabbit1
ports:
- "5672:5672"
- "15672:15672"
environment:
- RABBITMQ_DEFAULT_USER=myuser
- RABBITMQ_DEFAULT_PASS=mypass
rabbit2:
image: bijukunjummen/rabbitmq-server:3.7.0
hostname: rabbit2
links:
- rabbit1
environment:
- CLUSTERED=true
- CLUSTER_WITH=rabbit1
- RAM_NODE=true
ports:
- "5673:5672"
- "15673:15672"
rabbit3:
image: bijukunjummen/rabbitmq-server:3.7.0
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
