向 k8s 节点添加第二个磁盘

Question

我创建了一个 k8s 集群，所以现在我必须向我的节点添加第二个磁盘

这是我的节点组配置

resource "aws_eks_node_group" "node_group" {
  cluster_name = aws_eks_cluster.pm_eks.name
  node_group_name = "${var.appConfig_subdomain}-NodeGroup"
  node_role_arn = aws_iam_role.node-group-iam-role.arn
  subnet_ids = [
    aws_subnet.node-a_subnet.id,
    aws_subnet.node-b_subnet.id,
    aws_subnet.node-c_subnet.id
  ]
  instance_types = [
    "${var.aws_node_size}"
  ]
  disk_size = "${var.aws_node_diskSize}"
  scaling_config {
    desired_size = 3
    max_size     = 5
    min_size     = 3
  }
  remote_access {
    ec2_ssh_key = aws_key_pair.nodegroup-kp.key_name
    source_security_group_ids = [
      aws_security_group.allow_dmz.id
    ]
  } 
  provisioner "local-exec" {
    command = "echo '${tls_private_key.nodegroup-kp.private_key_pem}' > ./${var.appConfig_subdomain}-${var.appConfig_env}-nodegroup.pem"
  }
  # Ensure that IAM Role permissions are created before and deleted after EKS Node Group handling.
  # Otherwise, EKS will not be able to properly delete EC2 Instances and Elastic Network Interfaces.
  depends_on = [
    aws_iam_role_policy_attachment.AmazonEKSWorkerNodePolicy,
    aws_iam_role_policy_attachment.AmazonEKS_CNI_Policy,
    aws_iam_role_policy_attachment.AmazonEC2ContainerRegistryReadOnly,
  ]
}

请帮助我

提前致谢

为什么需要向节点添加第二个磁盘，这在 Kubernetes 中不是理想的方式，您应该在 Kubernetes 中查看

PersistentVolumeClaims

和

PersistentVolumes

，它会自动为您各自的 Pod 添加一个磁盘并将其附加到Pod 运行的相应节点。但不建议在worker节点添加磁盘。
