Adding a Listener to a Dedicated Load Balancer

Scenarios

Call the API to add a listener to a dedicated load balancer.

Prerequisites

• You have created a dedicated load balancer.
• You have obtained the ID of the dedicated load balancer.

Procedure

1. Add a listener.
   1. Send POST https://{elb_endpoint}/v3/{project_id}/elb/listeners. project_id indicates the project ID.
   2. Add X-Auth-Token to the request header.
   3. Ensure that the following parameters are passed in the request body:

      {
      	"listener": {
       		"protocol_port": 80, // Frontend port. The listener will use this port to receive requests.
      		"protocol": "HTTP", // Frontend protocol. The listener will use this protocol to receive requests.
      		"loadbalancer_id": "f77281cb-9f58-4347-8f82-2180d8bea789", // Load balancer that the listener is added to
      		"name": "my_listener" // Listener name
      	}
      }

   4. Check the response.
      • The request is successful if the following response is displayed:
