我正在使用平台条件来控制在AWS上运行的环境类型.有很多共享资源,但我需要某些EC2实例与预先制作的AMI,具体取决于数量条件.

  "Default": "linux",
  "Type": "String",
  "AllowedValues": [ "linux", "windows", "both" ],
  "ConstraintDescription": "Must enter either linux, windows, or both"
},

"Conditions" : {
  "LinuxPlatform" : {"Fn::Equals" : [{"Ref" : "Platform"}, "linux"]},
  "WindowsPlatform" : {"Fn::Equals" : [{"Ref" : "Platform"}, "windows"]},
  "BothPlatform" : {"Fn::Equals" : [{"Ref" : "Platform"}, "both"]}
},

在资源中,我想使用linux或windows来触发Windows或Linux Ec2创建,或者使用它们来部署所声明的每个ec2资源.

我fn:or在几个方面尝试了以下使用方法.

"Fn::Or": [{"Condition": "LinuxPlatform"}, {"Condition": "BothPlatform" }],

和...

"Condition" : {
   "Fn::Or" : …
