amazon-web-services - 如何在AWS Cloudformation的 "cidrblock"中获取子网的 "outputs"？

Question

我正在编写 AWS 代码结构。我必须打印子网的 Cidrblock。但这是行不通的。请帮忙

"Resources": {
    "Subnet": {
          "Type": "AWS::EC2::Subnet",
          "Properties": {
            "VpcId": {
              "Ref": "VPC"
            },
            "CidrBlock": "10.0.0.0/16",
          }
    },
    Outputs : {
      "SubnetCIDR": {
          "Value": {
            "Fn::GetAtt": [
              "Subnet",
              "CidrBlock"
            ]
          },
          "Description": "The CIDR"
        },
    }

这不起作用。上传模板时显示以下错误消息:

Template validation error: Template error: resource Subnet does not support attribute type CidrBlock in Fn::GetAtt

不支持。

如果您查看文档，唯一支持的属性是 AvailabilityZone
