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. The AWS Load Balancer Controller manages Kubernetes Services in a compatible way with the legacy aws cloud provider. alb.ingress.kubernetes.io/auth-idp-cognito specifies the cognito idp configuration. You may not have duplicate load balancer ports defined. The second security group will be attached to the EC2 instance(s) and allow all TCP traffic from the first security group created for the LoadBalancer.
