创建 AWS 日志组？

Question

我在创建属于更大 CloudFormation 模板的 AWS 日志组时遇到问题。所以只是为了测试，我只使用以下模板创建日志组

Parameters:
  LogGroupName:
    Type: String
    Description: 'cloudwatch log group name'
    Default: "test-log-group"
  LogGroupRetention:
    Type: Number
    Description: Retention period for log groups in cloudwatch
    Default: 30
  DelPolicy:
    Type: String
    Description: 'Deletion policy'
    Default: "Retain"

Resources:
  LLGO1WY:
    Type: 'AWS::Logs::LogGroup'
    Properties:
      awslogs-region: !Ref 'AWS::Region'
      LogGroupName: !Ref LogGroupName
      RetentionInDays: !Ref LogGroupRetention
      DeletionPolicy: !Ref DelPolicy

当我在手动创建堆栈（“创建堆栈”按钮）期间导入模板时，当我进入“导入概述”页面时，我得到以下信息。

There was an error creating this change set
The following resources to import [LLGO1WY] must have DeletionPolicy attribute specified in the template.

如果您查看documentation for AWS::Logs::LogGroup，它甚至没有将DeletionPolicy 定义为属性。请注意，如果我删除该属性，我会得到同样的错误。有什么线索吗？

Answer 1

AWS::Logs::LogGroup 没有 DeletionPolicy 属性。 DeletionPolicy 是您无法参数化的顶级属性。

我猜你可能想要：

Resources:
  LLGO1WY:
    Type: 'AWS::Logs::LogGroup'
    DeletionPolicy: Retain # <--- This is not property and must be here
    Properties:
      awslogs-region: !Ref 'AWS::Region'
      LogGroupName: !Ref LogGroupName
      RetentionInDays: !Ref LogGroupRetention
