Json CloudFormation EC2 Windows脚本

我只是从云的形成开始。我正在尝试创建两个具有自定义属性（VPC、安全组、子网和标记）的Windows EC2实例，但我不知道如何设置，我从标准AWS模板开始，并对其进行了修改，但失败了

{
  "cxawsprodnew01": {
    "Type": "AWS::EC2::Instance",
    "DeletionPolicy": "Retain",
    "Tags": [{ "tag": "" }],
    "Properties": {
      "ImageId": {
        "Fn::FindInMap": ["WindowsRegionMap", { "Ref": "AWS::Region" }, "AMI"]
      },
      "InstanceType": "r4.large",
      "InstanceInitiatedShutdownBehavior": "stop",
      "DisableApiTermination": "true",
      "VPCId": { "Type": "AWS::EC2::VPC::Id", "Ref": "vpc-9b34b5fd" },
      "SubnetId": { "Ref": "VpcSubnet1" },
      "SGUtilized": {
        "Type": "AWS::EC2::SecurityGroup::Id",
        "Ref": "ProdOctopusSG"
      },
      "BlockDeviceMappings": {
        "DeviceName": "/dev/sda1",
        "Ebs": {
          "VolumeType": "standard",
          "DeleteOnTermination": "false",
          "VolumeSize": "50"
        }
      }
    }
  }
}

我如何修改它以允许我添加所需的属性？否，我必须首先将它们设置为参数以调用它们？

是的，您可以在“属性”部分声明属性并引用它

{
  "Properties": { 
    "VpcId": { 
      "Type": "WS::EC2::VPC::Id"
      } 
  },
  "Resources":
    {
      "cxawsprodnew01":
        {
          "Type": "AWS::EC2::Instance",
          "DeletionPolicy": "Retain",
          "Tags": [{ "" }],
          "Properties":
            {
              ...
              "VPCId": { "Ref": "VpcId" },
              ....
            },
        },
    },
}
