Unable to deploy aws-load-balancer-controller on Kubernetes

Question

I am trying to deploy the aws-load-balancer-controller on my Kubernetes cluster on AWS = by following the steps given in https://docs.aws.amazon.com/eks/latest/userguide/aws-load-balancer-controller.html

After the yaml file is applied and while trying to check the status of the deployment , I get :

$ kubectl get deployment -n kube-system aws-load-balancer-controller
NAME                           READY   UP-TO-DATE   AVAILABLE   AGE
aws-load-balancer-controller   0/1     1            0           6m39s

I tried to debug it and I got this :

$ kubectl logs -n kube-system   deployment.apps/aws-load-balancer-controller
{"level":"info","logger":"controller-runtime.metrics","msg":"metrics server is starting to listen","addr":":8080"}
{"level":"error","logger":"setup","msg":"unable to create controller","controller":"Ingress","error":"the server could not find the requested resource"}

The yaml file is pulled directly from https://github.com/kubernetes-sigs/aws-load-balancer-controller/releases/download/v2.3.0/v2_3_0_full.yaml and apart from changing the Kubernetes cluster name, no other modifications are done.

Please let me know if I am missing some step in the configuration. Any help would be highly appreciated.

Answer 1

I am not sure if this helps, but for me the issue was that the version of the aws-load-balancer-controller was not compatible with the version of Kubernetes.

• aws-load-balancer-controller = v2.3.1
• Kubernetes/EKS = 1.22
