amazon-ec2 - CloudFormation Transform::包含参数

Question

我想使用 AWS 宏 Transform::Include 以及我的文件的一些动态参数。

Resources:
  'Fn::Transform':
    Name: 'AWS::Include'
    Parameters:
      TestMacroVariable: 
        Default: 2
        Type: Number
      Location: !Sub "s3://${InstallBucketName}/test.yaml"

测试.yaml:

DataAutoScalingGroup:
  Type: AWS::AutoScaling::AutoScalingGroup
  Properties:
    LaunchConfigurationName: 
      Ref: DataLaunchConfiguration
    MinSize: '1'
    MaxSize: '100'
    DesiredCapacity: 
      Ref: TestMacroVariable
...

调用后:aws cloudformation describe-stack-events --stack-name $stack

我得到:

"ResourceStatusReason": "The value of parameter TestMacroVariable under transform Include must resolve to a string, number, boolean or a list of any of these.. Rollback requested by user."

当我尝试这样做时:

Resources:
  'Fn::Transform':
    Name: 'AWS::Include'
    Parameters:
      TestMacroVariable: 2
      Location: !Sub "s3://${InstallBucketName}/test.yaml"

我得到:

"ResourceStatusReason": "Template format error: Unresolved resource dependencies [TestMacroVariable] in the Resources block of the template"

当我根本不提供 TestMacroVariable 时，错误是相同的。

尝试过不同的类型:字符串、数字、 bool 值、列表 - 它们都不起作用。

据我所知，您不能在 AWS::Include 的 Parameters 部分中拥有除 Location 键以外的任何内容。检查这里AWS DOC
