Docker images to run RabbitMQ cluster with dynamic number of nodes.
Once you clone the project run this command to build the custom image:
sh build.sh
If you want to run the cluster on one machine use docker-compose
docker-compose up -d
By default 4 nodes are started up this way:
version: '2.3'
services:
lb:
image: dockercloud/haproxy
ports:
- '5672:5672'
networks:
- dcmon-net
volumes:
- /var/run/docker.sock:/var/run/docker.sock
environment:
- TIMEOUT=connect 5000, client 0, server 0
links:
- rabbitmq
rabbitmq-master:
hostname: rabbitmq-master
image: rabbitmq-cluster:3.7.5-rc.1
environment:
- RABBITMQ_DEFAULT_USER=admin
- RABBITMQ_DEFAULT_PASS=admin
- ERLANG_COOKIE=SOMETHING_BLAH_BLAH_SECURE
ports:
- "15672:15672"
expose:
- "5672"
- "25672"
- "4369"
- "9100"
- "9101"
- "9102"
- "9103"
- "9104"
- "9105"
rabbitmq:
scale: 4
environment:
- CLUSTER_WITH=rabbitmq-master
- TCP_PORTS=5672
- ERLANG_COOKIE=SOMETHING_BLAH_BLAH_SECURE
expose:
- "5672"
- "25672"
- "4369"
- "9100"
- "9101"
- "9102"
- "9103"
- "9104"
- "9105"
If you need more or less node, just change the scale number:
rabbitmq:
scale: 5
Once cluster is up:
- The management console can be accessed at
http://hostip:15672
- The HA proxy manages the load balancing automatically. it manages the connections through 5672.
