Правильное CloudFormation для Route53 RecordSet для API-шлюза

/ 29 апреля 2020

Я пытаюсь развернуть шаблон CloudFormation (через AWS CLI), который содержит DynamoDB и некоторые Lambdas, обслуживаемые через API Gateway. Ниже приведен шаблон:

Часть, с которой у меня возникают трудности, - это AWS::Route53::RecordSetGroup, в частности запись для blogapi.zenithwebfoundry.com. По сути, создание стека происходит в RecordSetGroup с ошибкой: 

[RRSet with DNS name blogapi.zenithwebfoundry.com., type A contains an alias target that contains a hosted zone 108086391059049046 that is an invalid alias target., Tried to create an alias that targets z2fdtndataqyw2., type A in zone Z08366712O4E48ODE3XHX, but the alias target name does not lie within the target zone]

Я пробовал различные перестановки, в том числе пытался использовать установленную здесь HostedZone: 

  BlogAPIHostedZone:
    Type: AWS::Route53::HostedZone
    Properties:
      Name: !Ref BlogAPIDomainName

Надеясь, что это мог бы предоставить действительную ссылку, но он потерпел неудачу с другой ошибкой, по существу говоря, что запись не существует.

Поэтому мне интересно, как настроить набор записей с псевдонимом, который указывает на API-шлюз. Я видел много AWS doco, но, похоже, он направляется к конечным точкам Регионального API-шлюза (что, как мне кажется, немного особый случай) или к чисто консольным инструкциям, которые создают HostedZoneId до RecordSetGroup ( что позволяет жестко закодировать значение). Но как это сделать с помощью шаблона CloudFormation.

PS: пожалуйста, никаких ответов от serverless.com - это всего лишь AWS CloudFormation и развертывание стеков через AWS CLI. Меня интересуют только ответы, относящиеся к этому.

РЕДАКТИРОВАТЬ Следуя предложению, я изменил: 

DNSName: !Ref BlogAPIDomainName

на: 

DNSName: !GetAtt [BlogAPIDomainName, DistributionDomainName]

Развертывание фактически завершено. Так что спасибо.
