Installing RabbitMQ for MQTT¶

This section explains the steps to configure RabbitMQ for MQTT. It highlights the differences between the old RabbitMQ clusters (which need the x-delayed-message plugin) and the new one (which supports MQTT).

Older RabbitMQ clusters are still in use, requiring the x-delayed-message plugin for both connectivity and IoT exchanges.
The new RabbitMQ cluster provides MQTT functionality but is not yet integrated with the older version.

Prerequisites¶

The following requirements must be fulfilled for proceeding:

Chart repository
Chart version: 11.2.0
App version: 3.11.4
CPU: 1000m
Memory: 2Gi
