Amazon cloudformation 如何为AWS ElastiCache创建子网？

我偶然发现通过cloudformation模板创建2个子网供elasticache使用

下面是代码示例

"SubnetGroup" : {
"Type" : " "SubnetIds" : [ { "Ref" : "Subnet1" }, { "Ref" : "Subnet2" } ]",
"Properties" : {
    "Description" : "Cache Subnet Group",
    "SubnetIds" : [ { "Ref" : "Subnet1" }, { "Ref" : "Subnet2" } ]
}
}

我理解对象的逻辑，但我不知道如何创建

 "SubnetIds" : [ { "Ref" : "**Subnet1**" }, { "Ref" : "**Subnet2**" } ]

我不知道对象aws:ec2:：subnet是否能够为对象“aws:：ElastiCache:：SubnetGroup”创建子网

下面的代码能否为“AWS:：ElastiCache:：SubnetGroup”创建子网

或者是否有“AWS:：ElastiCache:：Subnet”来创建仅用于ElastiCache目的的子网，而我在文档中找不到该子网？

答案是肯定的-您引用了AWS:：ElastiCache:：SubnetGroup中的AWS:：EC2:：Subnet。下面是我的代码中的一个示例：

子网：

"subnet9732c5f2": {
  "Type": "AWS::EC2::Subnet",
  "Properties": {
    "CidrBlock": "10.5.2.0/24",
    "AvailabilityZone": "eu-west-1b",
    "VpcId": {
      "Ref": "vpcc140a7a4"
    },
    "Tags": [
      {
        "Key": "Name",
        "Value": "Private subnet #2"
      }
    ]
  }
}

子网组：

"cachesubnetgroup": {
  "Type" : "AWS::ElastiCache::SubnetGroup",
  "Properties" : {
    "Description" : "Cache Subnet for UAT",
    "SubnetIds" : [ 
        { 
            "Ref" : "subnet9732c5f2" 
        }, 
        {   
            "Ref" : "AnotherSubnetId" 
        }
    ]
  }
}

我收到错误“子网组属于不同的VPC”。Cloudformation正在尝试在默认VPC中创建子网组。而子网具有指定的专有网络。还尝试在子网组中指定VPC ID并获取“遇到不支持的属性VpcId”

"subnet9732c5f2": {
  "Type": "AWS::EC2::Subnet",
  "Properties": {
    "CidrBlock": "10.5.2.0/24",
    "AvailabilityZone": "eu-west-1b",
    "VpcId": {
      "Ref": "vpcc140a7a4"
    },
    "Tags": [
      {
        "Key": "Name",
        "Value": "Private subnet #2"
      }
    ]
  }
}

"cachesubnetgroup": {
  "Type" : "AWS::ElastiCache::SubnetGroup",
  "Properties" : {
    "Description" : "Cache Subnet for UAT",
    "SubnetIds" : [ 
        { 
            "Ref" : "subnet9732c5f2" 
        }, 
        {   
            "Ref" : "AnotherSubnetId" 
        }
    ]
  }
}
