AWS CloudFormation YAML！或功能

Question

错误：“模板验证错误：模板格式错误：条件只能是对参数和其他条件的布尔运算”

使用JSON条件阻止：

"Conditions" : { "CreateBetaResources" : {"Fn::Or" : [ {"Fn::Equals" : [{"Ref" : "Environment"}, "beta"]}, {"Fn::Equals" : [{"Ref" : "Environment"}, "eubeta"]} ]}, "CreateStagingResources" : {"Fn::Equals" : [{"Ref" : "Environment"}, "staging"]}, "CreateProdResources" : { "Fn::Or": [ {"Fn::Equals" : [{"Ref" : "Environment"}, "prod"]}, {"Fn::Equals" : [{"Ref" : "Environment"}, "euprod"]} ] } },

YAML阻止无效：

Conditions: CreateBetaResources: !Or [!Equals [!Ref "Environment", beta], !Equals [!Ref "Environment", eubeta]] CreateStagingResources: - !Equals [!Ref "Environment", staging] CreateProdResources: !Or [!Equals [!Ref "Environment", prod], !Equals [!Ref "Environment", euprod]]

为什么会发生这种错误？我已经搜索了关于“Fn :: Or”和条件的文档......似乎语法是正确的。我也尝试了很多很多其他格式，但这是最接近文档示例的格式。

实例化的正确方法！或者/！在YAML的条件块内等于如下：

Conditions:
 CreateBetaResources: !Or [!Equals [!Ref "Environment", beta], !Equals [!Ref "Environment", eubeta]]
 CreateStagingResources: !Equals [!Ref "Environment", staging]
 CreateProdResources: !Or [!Equals [!Ref "Environment", prod], !Equals [!Ref "Environment", euprod]]

在调用！Equals函数（ - ）之前不要包含列表标识符。
