在 AWS CloudFormation 的 DashboardBody 中使用 Fn::FindInMap

Question

我正在使用 CloudFormation 创建一个 AWS CloudWatch 控制面板，并尝试在 DashboardBody 正文中使用 Fn::FindInMap。但是，该值没有被成功替换。有人可以帮忙吗？

下面是我的代码：

Mappings:
  EnvSource:
    Dev:
      "SMSFailed": sns/us-east-1/XXX/DirectPublishToPhoneNumber/Failure

Resources: 
  MonitoringDashboard: 
    Type: "AWS::CloudWatch::Dashboard"
    Properties: 
      DashboardName:
        Monitoring-Test-Dashboard
      DashboardBody:
        !Sub "{\"widgets\":[{\"height\":6,\"width\":12,\"y\":1,\"x\":12,\"type\":\"log\",\"properties\":{\"query\":\"SOURCE 'Fn::FindInMap' : [ 'ABC', 'DomainParameters', 'DomainName'] | fields @timestamp, @message, delivery.providerResponse, status\\n| filter @message like //\\n|stats count(status) as ErrorCount by delivery.providerResponse\\n| sort @timestamp asc\",\"region\":\"us-east-1\",\"title\":\"SMS Failed\",\"view\":\"table\"}}]}"

输出：

Answer 1

您可以使用Sub 中的list form：

Resources: 
  MonitoringDashboard: 
    Type: "AWS::CloudWatch::Dashboard"
    Properties: 
      DashboardName:
        Monitoring-Test-Dashboard
      DashboardBody:
        !Sub 
           - "{\"widgets\":[{\"height\":6,\"width\":12,\"y\":1,\"x\":12,\"type\":\"log\",\"properties\":{\"query\":\"SOURCE ${FindInMap} | fields @timestamp, @message, delivery.providerResponse, status\\n| filter @message like //\\n|stats count(status) as ErrorCount by delivery.providerResponse\\n| sort @timestamp asc\",\"region\":\"us-east-1\",\"title\":\"SMS Failed\",\"view\":\"table\"}}]}"
           - DomainName: !FindInMap [ 'ABC', 'DomainParameters', 'DomainName']
