Prerequisites

The following are required to run the queue target connector:

• kubemq cluster
• kubemq-sources deployment

Configuration

Queue target connector configuration properties:

Properties Key	Required	Description	Example
address	yes	kubemq server address (gRPC interface)	kubemq-cluster-grpc.kubemq.svc.cluster.local:50000
channel	yes	set send request default channel	"queue"
client_id	no	set client id	"client_id"
auth_token	no	set authentication token	JWT token
expiration_seconds	no	set when the message will expire	"30"
delay_seconds	no	set how long to delay the delivery of the message	"10"
max_receive_count	no	set how many rejects before sending to dead-letter	"3"
dead_letter_queue	no	set dead-letter queue for each message	"queue"

Example:

bindings:
  - name:  queue-binding 
    properties: 
      log_level: error
      retry_attempts: 3
      retry_delay_milliseconds: 1000
      retry_max_jitter_milliseconds: 100
      retry_delay_type: "back-off"
      rate_per_second: 100
    source:
      kind: http
      name: http-post-source
      properties:
        "methods": "post"
        "path": "/queue"
    target:
      kind: kubemq.queue # Sources kind
      name: queue-target 
      properties: 
        address: "kubemq-cluster-grpc.kubemq.svc.cluster.local:50000"
        channel: "queue.http"
        client_id: "cluster-a-queue-connection"
        auth_token: ""
        delay_seconds: "10"
        max_receive_count: "3"
        expiration_seconds: "30"
        dead_letter_queue: "dead-queue"
