CreateListener - Elastic Load Balancing
Request ParametersResponse ElementsErrorsExamplesSee Also

CreateListener

Creates a listener for the specified Application Load Balancer, Network Load Balancer, or Gateway Load Balancer.

To update a listener, use ModifyListener. When you are finished with a listener, you can delete it using DeleteListener. If you are finished with both the listener and the load balancer, you can delete them both using DeleteLoadBalancer.

For more information, see the following:

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple listeners with the same settings, each call succeeds.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

Create an HTTPS listener

This example creates an HTTPS listener for the specified Application Load Balancer that forwards requests to the specified target group. Note that you must specify a default certificate for an HTTPS listener. You can create and manage your certificates using AWS Certificate Manager (ACM). Alternatively, you can create a certificate using SSL/TLS tools, get the certificate signed by a certificate authority (CA), and upload the certificate to AWS Identity and Access Management (IAM).
