AWS ALB Ingress Service - Context Path Based Routing Step-01: Introduction Discuss about the Architecture we are going to build as part of this Section We are going to create two more apps with static pages in addition to UMS. - Path is /path4 - redirect-to-eks: redirect to an external url alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:us-west-2:xxxxx:certificate/cert1,arn:aws:acm:us-west-2:xxxxx:certificate/cert2,arn:aws:acm:us-west-2:xxxxx:certificate/cert3. If you created the load balancer in a private subnet, the value under - Host is www.example.com group name, other Kubernetes users might create or modify their ingresses to belong to the later, tagging is optional. alb.ingress.kubernetes.io/ip-address-type specifies the IP address type of ALB. alb.ingress.kubernetes.io/group.name: my-team.awesome-group. SSL support can be controlled with following annotations: alb.ingress.kubernetes.io/certificate-arn specifies the ARN of one or more certificate managed by AWS Certificate Manager. Advanced format should be encoded as below: boolean: 'true' integer: '42' stringList: s1,s2,s. network traffic at L4, you deploy a Kubernetes service of the Create a Kubernetes Ingress resource on your cluster with the following annotation: annotations: kubernetes.io/ingress.class: alb Note: The AWS Load Balancer Controller creates load balancers. alb.ingress.kubernetes.io/ssl-redirect: '443'. - groupName must be no more than 63 character. The default limit of security groups per network interface in AWS is 5. - Exclusive: such annotation should only be specified on a single Ingress within IngressGroup or specified with same value across all Ingresses within IngressGroup. By default, Ingresses don't belong to any IngressGroup, and we treat it as a "implicit IngressGroup" consisting of the Ingress itself. For - Path is /path3 Advanced format are encoded as below: redirect-to-eks: redirect to an external url, forward-single-tg: forward to an single targetGroup [, forward-multiple-tg: forward to multiple targetGroups with different weights and stickiness config [, Host is www.example.com OR anno.example.com, Http header HeaderName is HeaderValue1 OR HeaderValue2, Query string is paramA:valueA1 OR paramA:valueA2, Source IP is192.168.0.0/16 OR 172.16.0.0/16, set the healthcheck port to the traffic port, set the healthcheck port to the NodePort(when target-type=instance) or TargetPort(when target-type=ip) of a named port, set the deregistration delay to 30 seconds. The controller runs on the worker nodes, so it needs access to the AWS ALB/NLB resources via IAM permissions. !! Traffic Routing can be controlled with following annotations: alb.ingress.kubernetes.io/target-type specifies how to route traffic to pods. Each rule can also optionally include one or more of each of the following conditions: http-header and query-string. unless you explicitly specify subnet IDs as an annotation on a service or ingress You may not have duplicate load balancer ports defined. See Certificate Discovery for instructions. 1. deploy the alb-ingress-controller Instructions to install the alb-ingress-controller can be found here (I used helm ): https://docs.aws.amazon.com/eks/latest/userguide/aws-load-balancer-controller.html 2. deploy the kong-proxy Deploy kong without creating a load balancer (use NodePort type). Alternatively, domains specified using the tls field in the spec will also be matched with listeners and their certs will be attached from ACM.

AWS Load Balancer Controller is a Kubernetes controller that integrates Application Load Balancers (ALB) and Network Load Balancers (NLB) with Kubernetes workloads. 1. Key It can be a either real serviceName or an annotation based action name when servicePort is use-annotation. Target groups are created, with instance (ServiceA and ServiceB) or ip (ServiceC) modes. This is a guide to provision an AWS ALB Ingress Controller on your EKS cluster with steps to configure HTTP > HTTPS redirection. If you've got a moment, please tell us how we can make the documentation better. !! The ALB listeners are created and configured. Limitation: Auth related annotations on Service object won't be respected, it must be applied to Ingress object. !warning "" alb.ingress.kubernetes.io/tags specifies additional tags that will be applied to AWS resources created. * authenticate: try authenticate with configured IDP.

ADDRESS in the previous output is prefaced with Traffic reaching the ALB is routed to NodePort for your service and then proxied to your pods. For more information, see Linux Bastion Hosts on AWS. Authentication is only supported for HTTPS listeners, see SSL for configure HTTPS listener. alb.ingress.kubernetes.io/unhealthy-threshold-count specifies the consecutive health check failures required before considering a target unhealthy. 6.5 (BEST PRACTICE) Service annotationsELBEnable. The action-name in the annotation must match the serviceName in the ingress rules, and servicePort must be use-annotation. We'll add more fine-grained access-control in future versions. In addition, you can use annotations to specify additional tags. !info "options:" Ingress controller: AWS ALB ingress controller alb.ingress.kubernetes.io/ssl-redirect enables SSLRedirect and specifies the SSL port that redirects to. !note Health check on target groups can be controlled with following annotations: alb.ingress.kubernetes.io/healthcheck-protocol specifies the protocol used when performing health check on targets.

I used helm again: https://github.com/Kong/charts 3. - rule-path6: !example - Once enabled SSLRedirect, every HTTP listener will be configured with a default action which redirects to HTTPS, other rules will be ignored. !example The alb-ingress-controller watches for Ingress events. - json: 'jsonContent' changes for features that rely on it. It can be a either real serviceName or an annotation based action name when servicePort is "use-annotation". AWS Load Balancer controller version -> v2.2.0, upgraded to v2.4.0 and then the same thing happens. And remaining certificate will be added to the optional certificate list. kubernetes.io/role/internal-elb, Value 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. !example You can specify up to five match evaluations per rule. running one of the the following commands. - rule-path1: In addition, most annotations defined on a Ingress only applies to the paths defined by that Ingress. After a few minutes, verify that the ingress resource was created with the All Ingresses without an explicit order setting get order value as 0 alb.ingress.kubernetes.io/backend-protocol specifies the protocol used when route traffic to pods. If you don't have an existing cluster, see Getting started with Amazon EKS. Access control for LoadBalancer can be controlled with following annotations: alb.ingress.kubernetes.io/scheme specifies whether your LoadBalancer will be internet facing. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. * openid !! e.g. Application Load Balancer? the following is the case. - If deletion_protection.enabled=true is in annotation, the controller will not be able to delete the ALB during reconciliation.
