Elastic Load Balancing

{'AlpnPolicy': ['string']}

{'Listeners': {'AlpnPolicy': ['string']}}

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

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.

For more information, see Listeners for Your Application Load Balancers in the Application Load Balancers Guide and Listeners for Your Network Load Balancers in the Network Load Balancers Guide .

{'AlpnPolicy': ['string']}

{'Listeners': {'AlpnPolicy': ['string']}}

Replaces the specified properties of the specified listener. Any properties that you do not specify remain unchanged.

Changing the protocol from HTTPS to HTTP, or from TLS to TCP, removes the security policy and default certificate properties. If you change the protocol from HTTP to HTTPS, or from TCP to TLS, you must add the security policy and default certificate properties.

To add an item to a list, remove an item from a list, or update an item in a list, you must provide the entire list. For example, to add an action, specify a list with the current actions plus the new action.
