[Feature Request] Add Ingress/Service object annotations to support recently added HTTP client keepalive duration
Is your feature request related to a problem?
Elastic Load Balancing team recently released HTTP client keepalive duration which can be configured for ALBs -> https://aws.amazon.com/about-aws/whats-new/2024/03/application-load-balancer-http-keepalive-duration/
This keepalive value specifies the maximum amount of time that ALB will maintain an HTTP connection with a client before closing the connection.
Describe the solution you'd like Specify this duration value via Ingress/Service object annotations.
Describe alternatives you've considered Configuring manually via awscli or console in meantime.

From what I understand, annotations are just a key/value pairing of the options available to the ALB. And seeing that KAT is a fairly recent addition we can see how our annotation list would be out of date.
We can confirm that you can set client keepalive time (KAT) by simply including annotation:
For example: alb.ingress.kubernetes.io/load-balancer-attributes: client_keep_alive.seconds=3600
We are working to update the docs for future references
