如何在AWS CDK中创建托管区域？

Question

您好，我正在使用AWS CDK为使用ELB和ECS部署的应用程序创建托管区域。我熟悉云形成，下面是我的样例云形成模板。

LocationServiceRoute53:
    Type: "AWS::Route53::RecordSet"
    Properties:
      HostedZoneId: !ImportValue "infra-r53-zones-region::PrivateZoneId"
      Comment: "Zone alias targeted to LoadBalancer"
      Name:
        !Join
        - "."
        - - "app"
          - "locationservices"
          - !ImportValue "infra-r53-zones-region::PrivateZoneName"

      Type: "A"
      AliasTarget:
        # yamllint disable-line rule:line-length
        HostedZoneId: {'Fn::ImportValue': !Sub 'location-agent-alb${StackSuffix}::MWSLoadBalancerHostedZoneId'}
        # yamllint disable-line rule:line-length
        DNSName: {'Fn::ImportValue': !Sub 'location-agent-alb${StackSuffix}::MWSLoadBalancerDNSName'}

我用CDK重写，如下所示。

 hostedZone = route.HostedZone.from_hosted_zone_attributes(self, 'HostedZone', hosted_zone_id='some id ', zone_name='zone name')
    recordName = 'record name'

    targetAlias = route.AddressRecordTarget.from_alias(alias_target )
    route.ARecord(self, id='AliasRecord', zone = hostedZone, comment='Zone alias targeted to LoadBalancer',
    record_name=recordName, target=targetAlias)

这是抛出AttributeError: 'ApplicationLoadBalancer' object has no attribute 'dns_name'，有人能帮我写一下吗？任何帮助都将不胜感激。谢谢

Answer 1

这对我很有效。

 hostedZone = route.HostedZone.from_hosted_zone_attributes(self, 'HostedZone', hosted_zone_id='some id ', zone_name='zone name')
        recordName = 'r name'
        route.ARecord(self, id='AliasRecord', zone = hostedZone, comment='Zone alias targeted to LoadBalancer',
        record_name=recordName, target = route.RecordTarget.from_alias(route_targets.LoadBalancerTarget(lb)))

Answer 2

我采用了我的工作代码，并根据您的情况进行了调整：

const cdk = require('@aws-cdk/core')
const route53 = require('@aws-cdk/aws-route53')
const alias = require('@aws-cdk/aws-route53-targets')

const hostedZoneId = cdk.Fn.importValue(`infra-r53-zones-region::PrivateZoneId`)
const zone = route53.HostedZone.fromLookup(this, hostedZoneId, {domainName: 'xxxx-xxx.com'});
new route53.ARecord(this, 'AliasRecord', {
  zone,
  target: route53.RecordTarget.fromAlias(new alias.LoadBalancerTarget(<loadBalancer>)),
  recordName: <your_domain_name>
});
