When using target-type: instance with a service of type "NodePort", the healthcheck port can be set to traffic-port to automatically point to the correct port. * allow: allow the request to be forwarded to the target. This limit is quickly reached when multiple load balancers are provisioned by the controller without this annotation, therefore it is recommended to set this annotation to a self-managed security group (or request AWS support to increase the number of security groups per network interface for your AWS account). Deploy a sample application to verify that the AWS Load Balancer Controller creates a public Application Load Balancer because of the Ingress object. The full ingress .
