Reading the Migrate from v1 to v2 document I expected this would preserve our existing load balancer, which it did after the new controller was started. Health check path annotation should be moved to respective node port services if we have to route to multiple targets using single load balancer. This module can be used to install the ALB Ingress controller into a "vanilla" Kubernetes cluster (which is the default) or it can be used to integrate tightly with AWS-managed EKS clusters which allows the deployed pods to use IAM roles for service accounts. None of the load balancer annotations are respected by the ALB. Annotation section of ingress controller-service.yaml to support NLB instead of ALB / CLB controller-configmap.yaml section Removed proxy-real-ip-cidr: XXX.XXX.XXX/XX controller-deployment.yaml section Changed deployment kind from Deployment to DaemonSet to run the controller on all the worker nodes You can check if the Ingress Controller successfully applied the configuration for an Ingress. I followed each and every step carefully but my ingress controller status is always showing pending I tried to see the logs with the command "kubectl logs --namespace kube-system $(kubectl get po --namespace kube-system | egrep -o [a-zA-Z09-]alb-ingress[a-zA-Z09-])" but it is not showing SSL termination, with ACM certificate provide from AWS. For more information, see Ingress specification on GitHub. AWS ALB Ingress Controller; GCP GLBC/GCE-Ingress Controller; The major advantage of using a cloud-based Ingress Controller is native integration with other cloud services. Seeing two ingresses with same ALB address is confusing, but merge ingress controller is just propagating the status of merged ingress blog-ingress to blog ingress. It satisfies Kubernetes Ingress resources by provisioning Application Load Balancers. The Kubernetes Ingress resource can be annotated with arbitrary key/value pairs.
