Terraform:如何将Windows工作节点添加到eks集群？

Question

我在AWS (Linux)上使用terraform代码配置的EKS集群(1.16)和工作节点。下面的代码用于创建eks工作节点(Linux)：

resource "aws_eks_node_group" "default-worker-nodes-group" {
  cluster_name    = "${var.eks_cluster_name}"
  node_group_name = "${var.eks_cluster_node_group_name}"
  node_role_arn   = "${var.eks_worker_node_role_arn}"
  subnet_ids      = ["${var.eks_worker_subnet_ids}"]
  ami_type        = "${var.ami_type}"
  instance_types  = "${var.instance_type}"
  disk_size       = "${var.volume_size}"
  release_version = "${var.release_version}"
  version         = "${var.eks_cluster_version}"

  remote_access {
    ec2_ssh_key               = "${var.ec2_ssh_key}"
    source_security_group_ids = ["${var.eks_worker_security_groups_ids}"]
  }

 
}

我想添加其他Windows工作节点。该怎么做呢？

我在下面定义了Linux节点的实例角色的ARN。对于Windows，我可以使用与Linux相同的角色吗？也就是说，Windows节点的实例角色的ARN与Linux节点的实例角色的ARN相同？

#eks workers roles
resource "aws_iam_role" "eks-workernode-role" {
  name = "${var.eks_workernode_iam_role_name}"

  assume_role_policy = <<POLICY
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "ec2.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
POLICY
}

data:
  mapRoles: |
    - rolearn: ${aws_iam_role.eks-workernode-role.arn}
      username: system:node:{{EC2PrivateDNSName}}
      groups:
        - system:bootstrappers
        - system:nodes

您需要使用的AMI是Windows-AMI，请参阅Amazon EKS optimized Windows AMIs。

在aws-auth ConfigMap中，您还需要一个稍微不同的角色，如Launching self-managed Windows nodes中所述，其中的mapRoles类似

      groups:
        - system:bootstrappers
        - system:nodes
        - eks:kube-proxy-windows
