AWS-based peer discovery backend for RabbitMQ 3.7.0+

RabbitMQ Peer Discovery AWS

This is an AWS-based implementation of RabbitMQ peer discovery interface (new in 3.7.0, previously available in the rabbitmq-autocluster plugin by Gavin Roy).

This plugin only performs peer discovery and most basic node health monitoring using AWS (EC2) APIs as data source. Please get familiar with RabbitMQ clustering fundamentals before attempting to use it.

While it may seem at times that this is a RabbitMQ cluster management solution, it is not. Cluster provisioning and most of Day 2 operations such as proper monitoring are not in scope for this plugin.

Supported RabbitMQ Versions

This plugin requires RabbitMQ 3.7.0 or later.

For a AWS-based peer discovery and cluster formation mechanism that supports 3.6.x, see rabbitmq-autocluster.


This plugin ships with RabbitMQ as of 3.7.0. There is no need to install it separately. Enable the plugin in offline mode before the node is first started:

rabbitmq-plugins --offline enable rabbitmq_peer_discovery_aws
