And while upgrading to 18.0.0 also, I was expecting similar o/p But rather, it was throwing the above error which i pasted ### Actual Behavior Error: Get "http://localhost/apis/rbac.authorization.k8s.io/v1/clusterroles/system:aggregated-metrics-reader": dial tcp 127.0.0.1:80: connect: connection refused ¦ ¦ with module.eks-setup.kubernetes_cluster_role.aggregated_metrics_reader, ¦ on ../../modules/eks/metricsserver.tf line 32, in resource "kubernetes_cluster_role" "aggregated_metrics_reader": ¦ 32: resource "kubernetes_cluster_role" "aggregated_metrics_reader" { ¦ ? ? ¦ Error: Get "http://localhost/apis/rbac.authorization.k8s.io/v1/clusterroles/system:metrics-server": dial tcp 127.0.0.1:80: connect: connection refused ¦ ¦ with module.eks-setup.kubernetes_cluster_role.this, ¦ on ../../modules/eks/metricsserver.tf line 50, in resource "kubernetes_cluster_role" "this": ¦ 50: resource "kubernetes_cluster_role" "this" { ¦ ? ? ¦ Error: Get "http://localhost/api/v1/namespaces/kube-system/services/metrics-server": dial tcp 127.0.0.1:80: connect: connection refused ¦ ¦ with module.eks-setup.kubernetes_service.this, ¦ on ../../modules/eks/metricsserver.tf line 136, in resource "kubernetes_service" "this": ¦ 136: resource "kubernetes_service" "this" { ¦ ### Steps to Reproduce terraform plan ### Additional Context My backend.tf file looks like the attached screenshot ### References _No response_ ### Generative AI / LLM assisted development? _No response_
