MQTT source connector configuration properties:

Properties Key	Required	Description	Example
host	yes	mqtt connection host	"localhost:1883"
topic	yes	set mqtt subscription topic	"queue"
dynamic_mapping	yes	set if to map mqtt topic to kubemq channel	"true"
username	no	set mqtt username	"username"
password	no	set mqtt password	"password"
client_id	no	mqtt connection string address	"client_id"
qos	no	set mqtt subscription QoS	"0"

Example:

bindings:
  - name: mqtt-kubemq-event
    source:
      kind: messaging.mqtt
      name: mqtt-source
      properties:
        host: "localhost:1883"
        dynamic_map: "true"
        topic: "queue"
        username: "username"
        password: "password"
        client_id: "client_id"
        qos: "0"
    target:
      kind: kubemq.events
      name: target-kubemq-events
      properties:
        address: "kubemq-cluster:50000"
