How to get a cluster of RabbitMQ using Docker

rabbimq-docker.md

In just 5 minutes

You will need the following tools:

• curl or wget
• docker-compose

Blazing fast version

curl https://raw.githubusercontent.com/Zerpet/docker-rabbitmq-cluster/version/3.6/compose-templates/3-disc-nodes.yml > docker-compose.yml
docker-compose -p blazing-fast-rabbit up -d

• Wait 30 seconds
• Access Management UI http://127.0.0.1:15672/#/

That was so fast we have 4 minutes left! 🐇

# Interactive terminal
docker-compose -p blazing-fast-rabbit exec rabbitmq-server1 /bin/bash

# Any rabbitmqctl command
docker-compose -p blazing-fast-rabbit exec rabbitmq-server1 rabbitmqctl report

Ok, we had fun. Now it's time to clean up before we go.

docker-compose -p blazing-fast-rabbit down

Steps explanation.md

What just happened?

• We used curl to download a Docker Compose template for RabbitMQ 3.6 from the image repo
• We started a new Docker Compose "project" named blazing-fast-rabbit using the template
• The Docker image has an automated procedure in the entry script to automatically join a RabbiMQ cluster
• The management UI ports are exposed and forwarded to localhost ports 15672, 15673 and 15674
• We can get an interactive Bash terminal to the container
• We can execute any command in the container without an interactive terminal!
• We left everything as we found it

The last step is a destructive action. If you wish to reuse the cluster at a later time, you can use stop/start commands in compose.

docker-compose -p blazing-fast-rabbit stop
docker-compose -p blazing-fast-rabbit start

Caveats

• The YAML file docker-compose.yml must be in the current directory
  • Otherwise, we have to specify the path using the option -f
• The image has some not fun limitations
