amazon-web-services - 如何为 CfnDistribution 添加 Route53 别名？

Question

亚马逊有 this example了解如何为您的 CloudFrontWebDistribution 创建自定义别名:

import route53 = require('@aws-cdk/aws-route53');
import targets = require('@aws-cdk/aws-route53-targets');

new route53.AaaaRecord(this, 'Alias', {
  zone: myZone,
  target: route53.RecordTarget.fromAlias(new targets.CloudFrontTarget(distribution))
});

这看起来 super 简单。

但是，由于 Lambda@Edge 的限制，我不得不改用低级 CfnDistribution。有没有办法为那个创建别名？直接或使用一些巫术从低级 CfnDistribution 创建高级 CloudFrontWebDistribution 构造？

Answer 1

我从 aws-route53-targets 模块中提取了 CloudFrontTarget 代码并对其进行了调整，使其成为:

class CfnDistributionTarget implements route53.IAliasRecordTarget {
  private readonly distribution: CfnDistribution
  /**
   * The hosted zone Id if using an alias record in Route53.
   * This value never changes.
   */
  static readonly CLOUDFRONT_ZONE_ID = 'Z2FDTNDATAQYW2'
  constructor(distribution) {
    this.distribution = distribution
  }
  bind(_record: route53.IRecordSet): AliasRecordTargetConfig {
    return {
      hostedZoneId: CfnDistributionTarget.CLOUDFRONT_ZONE_ID,
      dnsName: this.distribution.attrDomainName
    }
  }
}
