Eclipse MQTT Installation

Installation of the MQTT brokers and storage (queues) is required for establishing communications towards the DeviceNodes. This is a prerequisite of the Open Connectors, they cannot operate without it.

Regarding the MQTT brokers, they have to be available and reachable outside the cluster, and therefore possibly enable authentication/authorization procedures for the edge devices (DeviceNodes).

The current AsyncAPI temporarily adresses the Authentication & Authorization via username/password. This must be considered as temporaty and is mentioned for the sake of completeness of the spicification.

Configuration of the MQTT happens via the mosquitto.conf. The MQTT, should not be deployed alongside the Open Connectors, as they are a prerequisite.
