我在公共子网中创建了一个具有 1 个工作节点的新 EKS 集群。我能够查询节点、连接到集群并运行 pod 创建命令，但是，当我尝试创建 pod 时，它失败并出现通过描述 pod 得到的以下错误。请指导。

    Tolerations:                 node.kubernetes.io/not-ready:NoExecute op=Exists for 300s
                                 node.kubernetes.io/unreachable:NoExecute op=Exists for 300s

我使用以下方法成功创建了以下四个资源Cloud Formation Template (CFT)：

1. 专有网络
2. 子网
3. 互联网网关
4. 连接网关

现在，我正在尝试使用 EC2 实例创建一个安全组，这是代码。

  Type: AWS::EC2::SecurityGroup
  Properties:
      GroupDescription: Allow http and ssh to client host
      VpcId:

        ToPort: 80
        CidrIp: 0.0.0.0/0
      - IpProtocol: tcp
        FromPort: 22
        ToPort: 22
        CidrIp: 0.0.0.0/0

但是，当我在（CFT，如上所示，代码）中使用 Key …
