We'll use the alb.ingress.kubernetes.io/actions.${action-name} annotation to setup an ingress to redirect http traffic into https. An Ingress may be configured to give Services externally-reachable URLs, load balance traffic, terminate SSL / TLS and offer name-based virtual hosting. The list of things you can specify includes, but is not limited to, the health checks (done by Target Groups), the priority of the load balancer listener rule, and many more. Annotations can be added to Kubernetes ingress objects to customize the behavior of the provisioned Application Load Balancers. Clients send requests to the load balancer, and the load balancer sends them to targets, such as EC2 instances. A load balancer serves as the single point of contact for clients. After the load balancer receives a request, it evaluates the listener rules in priority order to determine which rule to apply, and then selects a target from the target group for the rule action. The alb-ingress-controller creates the AWS Application Load Balancer based on the annotations added in the ingress resource. My AWS Load Balancer Controller can't find my subnet in Amazon Elastic Kubernetes Service (Amazon EKS). For example, when you define a rule having two target groups with weights of 8 and 2, the load balancer will route 80 percent of the traffic to the first target group and 20 percent to the other. How to change service type to ALB in AWS EKS? In addition to the weighted target group, AWS announced the advanced request routingfeature in 2019. Verify that responses from the load balancer endpoint are always from application version 1: To perform the blue/green deployment, update the ingress annotation to move all weight to version 2: Verify that the responses from the load balancer endpoint are now always from application version 2: Instead of moving all traffic to version 2, we can shift the traffic slowly towards version 2 by increasing the weight on version 2 step by step. For more information, see View your subnet. Is it possible to change Arduino Nano sine wave frequency without using PWM? You can configure listener rules to route requests to different target groups based on the content of the application traffic. Why the wildcard "?" The benefits of using a NLB are: Since the Load Balancer service is dynamically created, we don't know the service name. Now, let's bind the custom domain to the ALB and SSL Certificates. This article demonstrates how we can achieve similar deployment strategies with native AWS Application Load Balancer by managing the Kubernetes ingress resource with the use of AWS Load Balancer Controller. You can check more on the documentation here. AWS Load Balancer controller manages the following AWS resources Application Load Balancers to satisfy Kubernetes ingress objects Network Load Balancers to satisfy Kubernetes service objects of type LoadBalancer with appropriate annotations Security updates Note: Deployed chart does not receive security updates automatically.
