amazon-web-services - CloudFormation 根据不存在列表值保留资源

Question

我将事件配置文件名称列表作为列表传递到我的 CloudFormation 模板:

  Profiles:
    Description: The comma-separated list of active profiles, such as "dev,test".
    Type: CommaDelimitedList
    Default: ""

如果我不在 dev 中运行，我想保留一个资源环境，即如果 "dev"不是 Profiles 中的字符串之一列表。这是我正在寻找的一些伪代码:

  MyBucket:
    Type: AWS::S3::Bucket
    # pseudocode
    DeletionPolicy: Profiles.contains("dev") ? Delete : Retain
    # hypothetical syntax
    DeletionPolicy: !Contains [!Ref Profiles, "dev", Delete, Retain]

CloudFormation 是否允许我根据字符串是否在参数列表中创建条件删除策略？

Answer 1

Does CloudFormation allow me to create a conditional deletion policy based upon whether a string is in a parameter list?

不幸的是没有。有一个 Fn::Contains 函数，但这只能在 CloudFormation 规则中使用:
