Cloudformation SNS模板验证错误

要跨不同堆栈使用属性,需要显式导出一端的值并导入到另一个堆栈中。

在你的情况下,你可能需要这样的东西:

堆栈:sns测试

{
    "Resources": {
        "MySNSTopic": {
            "Type": "AWS::SNS::Topic"
        }
    },
    "Outputs": {
        "MySNSTopicOutput": {
            "Description": "SNS topic arn",
            "Value": {
                "Ref": "MySNSTopic"
            },
            "Export": {
                "Name": {
                    "Fn::Sub": "${AWS::StackName}-MySNSTopicExport"
                }
            }
        }
    }
}

堆栈:sns订阅

{
  "Resources": {
    "MySubscription": {
      "Type": "AWS::SNS::Subscription",
      "Properties": {
        "Endpoint": "jens@apimeister.com",
        "Protocol": "email",
        "TopicArn": {
          "Fn::ImportValue" : "sns-test-MySNSTopicExport"
        }
      }
    }
  }
}
