RabbitMQ Peer Discovery Etcd

This is an etcd-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 etcd as a 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.

Supported etcd Versions

The plugin supports etcd 3.4 or later and uses the current stable v3 gRPC API.

Installation

This plugin ships with supported RabbitMQ versions. There is no need to install it separately.

As with any plugin, it must be enabled before it can be used. For peer discovery plugins it means they must be enabled or preconfigured before first node boot:

rabbitmq-plugins --offline enable rabbitmq_peer_discovery_etcd

Documentation

See RabbitMQ Cluster Formation guide.
