amazon-cloudformation - CloudFormation中如何同时定义和使用SSM参数？

Question

这是一个 SAM 模板（与 CloudFormation 模板相同）：

Globals:
    Function:
        Environment:
            Variables:
                BAR: '{{resolve:ssm:myparam:1}}'
...
    MyParam:
        Type: "AWS::SSM::Parameter"
        Properties:
            Name: myparam
            Type: String
            Value: 'REPLACE_ME' # must be defined manually in the AWS Console

我无法部署此堆栈，因为：

FAILED. Reason: Parameters: [ssm:myparam:1] cannot be found.

当然，我是在堆栈中创建这个参数……</p>

如何引用我在同一模板中创建的 SSM 参数？

您是否尝试通过Fn::GetAtt (!GetAtt MyParam.Value) 访问变量？

Globals:
    Function:
        Environment:
            Variables:
                BAR: !GetAtt MyParam.Value
...
    MyParam:
        Type: "AWS::SSM::Parameter"
        Properties:
            Name: myparam
            Type: String
            Value: 'REPLACE_ME' # must be defined manually in the AWS Console
