使用Terraform部署EKS节点组时出错

使用Terraform在EKS群集中部署节点组时遇到问题。该错误似乎是一个插件有问题，但我不知道如何解决它。

如果在AWS控制台（Web）中看到EC2，则可以看到集群的实例，但是集群中有此错误。

错误显示在我的管道中：

错误：等待EKS节点组（UNIR-API-REST-CLUSTER-DEV：node_sping_boot）创建：NodeCreationFailure：实例无法加入kubernetes集群。资源ID：
在资源“ aws_eks_node_group”“节点”中的EKS.tf第17行上的[i-05ed58f8101240dc8] ：

并在AWS控制台中显示错误：

这是我用来创建项目的Terraform中的代码：

将需要更多的日志吗？

根据AWS文档：

如果您在AWS管理控制台中收到错误“实例无法加入kubernetes集群”，请确保已启用集群的私有端点访问，或者已正确配置了CIDR块以进行公共端点访问。有关更多信息，请参阅Amazon EKS集群终端节点访问控制。

我注意到您正在切换子网的可用区：

resource "aws_subnet" "unir_subnet_cluster_1" {
  vpc_id = "${aws_vpc.unir_shop_vpc_dev.id}"
  cidr_block = "${var.SUBNET_CIDR_CLUSTER_1}"
  map_public_ip_on_launch = true
  availability_zone = "${var.ZONE_SUB_CLUSTER_2}"

你已经分配var.ZONE_SUB_CLUSTER_2给unir_subnet_cluster_1和var.ZONE_SUB_CLUSTER_1给unir_subnet_cluster_2。也许这可能是配置错误的原因。
