Question

我正在尝试从现有快照ID创建新的Sql服务器 - RDS实例（具有更多存储空间）。下面是我的CloudFormation模板抛出错误“模板包含错误：模板属性或属性无效[类型，属性]”

"MyDB" : {
  "Type" : "AWS::RDS::DBInstance",
   "Properties" : {
      "DBName" : { "Ref" : "NSGlobal" },
      "DBSnapshotIdentifier":"rds:xxxxxxxxx-2016-07-13-17-00",
      "AllocatedStorage" : "400",
      "DBInstanceClass" : "db.m2.xlarge",
      "EngineVersion" : "11.0"
   }
}

我从AWS网站http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-rds-database-instance.html#cfn-rds-dbinstance-masterusername复制了此模板并对其进行了定制。有什么问题？

Answer 1

您缺少Engine属性，请使用下面的模板。这是引擎的有效选项。

        "MyDB" : {
          "AWSTemplateFormatVersion" : "2010-09-09", 
          "Resources" : { 
          "DBInstance" : { 
          "Type": "AWS::RDS::DBInstance", 
          "Properties": { 
             "DBInstanceClass" : "db.m2.xlarge", 
             "AllocatedStorage" : "400", 
             "MasterUsername" : "myusername", 
             "MasterUserPassword" : "mypassword", 
             "DBSnapshotIdentifier":"xxxxxxxx-2016-07-13-17-00" 
         } 
      } 
    } 
}

Answer 2

这有效：

{
    "AWSTemplateFormatVersion" : "2010-09-09",
    "Resources" : {
        "DBInstance" : {
            "Type": "AWS::RDS::DBInstance",
            "Properties": {
                "DBInstanceClass" : "db.m2.xlarge", 
                "AllocatedStorage" : "400", 
                "MasterUsername" : "myusername", 
                "MasterUserPassword" : "mypassword", 
                "DBSnapshotIdentifier":"xxxxxxxx-2016-07-13-17-00" 
            }
        }
    }
}

MasterUserName和MasterUserPassword不是必需的，即使没有它们，模板也会有效。
