无法用地形创建新的EKS

Question

我在开发环境中创建一个新的EKS版本1.22有问题。我在Terraform注册表中使用该模块，因为它只用于测试目的(我们只想测试版本1.22)，因此对某些部分进行了微调。我使用的VPC是为测试EKS而创建的，还有两个公共子网和两个私有子网。

这是我的main.tf：

module "eks" {
  source  = "terraform-aws-modules/eks/aws"
  version = "18.21.0"

  cluster_name    = "EKSv2-update-test"
  cluster_version = "1.22"

  cluster_endpoint_private_access = true
  cluster_endpoint_public_access  = true

  cluster_addons = {
    coredns = {
      resolve_conflicts = "OVERWRITE"
    }
    kube-proxy = {}
    vpc-cni = {
      resolve_conflicts = "OVERWRITE"
    }
  }


  vpc_id     = "vpc-xxx" # eks-vpc
  subnet_ids = ["subnet-priv-1-xxx", "subnet-priv-2-xxx", "subnet-pub-1-xxx", "subnet-pub-2-xxx"]
}

Terraform在20分钟后应用超时(它只挂在module.eks.aws_eks_addon.this["coredns"]: Still creating... [20m0s elapsed]上)

这就是错误

│ Error: unexpected EKS Add-On (EKSv2-update-test:coredns) state returned during creation: timeout while waiting for state to become 'ACTIVE' (last state: 'DEGRADED', timeout: 20m0s)
│ [WARNING] Running terraform apply again will remove the kubernetes add-on and attempt to create it again effectively purging previous add-on configuration
│ 
│   with module.eks.aws_eks_addon.this["coredns"],
│   on .terraform/modules/eks/main.tf line 305, in resource "aws_eks_addon" "this":
│  305: resource "aws_eks_addon" "this" {

EKS被创建，但这显然不是要走的路。关于coredns，我遗漏了什么？

谢谢

addon编码至少需要2个集群节点才能满足其副本集的要求。
