  ### MQTT Broker
 
   - `forge.broker.enabled` (default `false`)
+  - `forge.broker.image` Allows the mosquitto broker container image to be overidden (default `iegomez/mosquitto-go-auth`)
   - `forge.broker.url` URL to access the broker from inside the cluster (default `mqtt://flowforge-broker.[namespace]:1883`)
   - `forge.broker.public_url` URL to access the broker from outside the cluster (default `ws://mqtt.[forge.domain]`, uses `wss://` if `forge.https` is `true`)
   - `forge.broker.hostname` the custom Fully Qualified Domain Name (FQDN) where the broker will be hosted (default `mqtt.[forge.domain]`)
