AWS CloudFormation：无法创建用于URL到URL映射的Route53记录资源

问题描述

我正在使用CloudFormation将应用程序部署到AWS。我正在创建一个将URL映射到URL的Route53记录。但是部署模板时失败了。

这是我在模板中的资源。

WebDNS:
    Type: AWS::Route53::RecordSetGroup
    Properties:
      HostedZoneName: waiyanhein.com.
      Comment: Weighted PRs for frontends.
      RecordSets:
        - Name: waiyanhein.com.
          Type: CNAME
          TTL: '900'
          SetIdentifier: Frontend
          Weight: 5
          ResourceRecords:
            - http://patheindirectorytesting.eba-zxqi6pge.eu-west-1.elasticbeanstalk.com/

部署后，出现以下错误。

{
            "StackId": "arn:aws:cloudformation:eu-west-1:733553390213:stack/patheindirectory/dd7eb5b0-e96c-11ea-bcdf-02e29081c656","EventId": "36f3bc50-e975-11ea-b9b2-0ae6d6014b56","StackName": "patheindirectory","LogicalResourceId": "patheindirectory","PhysicalResourceId": "arn:aws:cloudformation:eu-west-1:733553390213:stack/patheindirectory/dd7eb5b0-e96c-11ea-bcdf-02e29081c656","ResourceType": "AWS::CloudFormation::Stack","Timestamp": "2020-08-28T21:27:03.035000+00:00","ResourceStatus": "UPDATE_ROLLBACK_IN_PROGRESS","ResourceStatusReason": "The following resource(s) Failed to create: [WebDNS].

        },{

elasticbeanstalk.com/\"],\"SetIdentifier\":\"Frontend\",\"TTL\":\"900\",\"Weight\":\"5\",\"Name\":\"waiyanhein.com.\"}]}"
        },

模板有什么问题，我该如何解决？

我尝试使用它。

WebDNS:
        Type: AWS::Route53::RecordSetGroup
        Properties:
          HostedZoneName: waiyanhein.com.
          Comment: Weighted PRs for frontends.
          RecordSets:
            - Name: waiyanhein.com.
              Type: A
              AliasTarget:
                  DNSName: patheindirectorytesting.eba-zxqi6pge.eu-west-1.elasticbeanstalk.com
                  EvaluateTargetHealth: true
                  HostedZoneId: Z1LQECGX5PH1X
              SetIdentifier: Frontend
              Weight: 5

这次我遇到了这个错误。

解决方法

由于您的EB域中包含区域名称（eu-west-1），所以我认为最好的方法是为其设置别名记录：

Creating an Amazon Route 53 record that routes traffic to your Elastic Beanstalk environment

为此，您需要获取您所在区域的HostedZoneId，其名称为here，为Z1LQECGX5PH1X。

随后，您的RecordSet可能是：

    WebDNS:
        Type: AWS::Route53::RecordSetGroup
        Properties:
          HostedZoneName: waiyanhein.com.
          Comment: Weighted PRs for frontends.
          RecordSets:
            - Name: waiyanhein.com.
              Type: A
              AliasTarget:
                  DNSName: patheindirectorytesting.eba-zxqi6pge.eu-west-1.elasticbeanstalk.com
                  EvaluateTargetHealth: true
                  HostedZoneId: Z1LQECGX5PH1X
              SetIdentifier: Frontend
              Weight: 5
