Automatic RabbitMQ Rancher based Cluster

Overview

This container provides a Single instance / Automatic Clustered RabbitMQ Service.

Caveats

This docker image will not work on standard docker environments as it relies on Rancher's Metadata Service for the autodiscovery feature.

Features

• Fully configurable through Docker ENV vars
• Clustered RabbitMQ support
• Automatic node Discovery

Usage

Example Docker Compose - Multinode Cluster deployment

version: '2'
services:
  MessageQueue:
    image: rancher-auto-rabbitmq:latest
    environment:
      RABBITMQ_ERLANG_COOKIE: abcdefgh
      RABBITMQ_DEFAULT_USER: guest
      RABBITMQ_DEFAULT_PASS: guest
    stdin_open: true
    volumes:

    start_on_create: true
    health_check:
      response_timeout: 2000
      healthy_threshold: 2
      port: 5672
      unhealthy_threshold: 3
      initializing_timeout: 60000

Notes

• RABBITMQ_ERLANG_COOKIE is required for Node Clustering.
• If not specified, user/pass = guest/guest.
