AWS CDK Cross Account Route53

AWS CDK Constructs that define:

  • IAM role that can be used to allow discrete Route53 Record changes
  • Cross Account Record construct to create Route53 cross account Route53 records

These constructs allow you to create Route53 records where the zone exists in a separate AWS account to the Cloudformation Stack.

Getting started

yarn add @fallobst22/cdk-cross-account-route53

First create the role in the stack for the AWS account which contains the hosted zone.

// DNS Stack
const zone = new route53.PublicHostedZone(this, 'HostedZone', {
  zoneName: 'example.com',
});

new CrossAccountRoute53Role(this, 'WebRoute53Role', {
  roleName: 'WebRoute53Role',
  assumedBy: new iam.AccountPrincipal('22222222'), // Web Stack Account
  zone,
  records: [{ domains: ['www.example.com'] }],
 });

Then in the child stack create the records

const hostedZoneId = 'Z12345'; // ID of the zone in the other account

const distribution = new cloudfront.Distribution(this, 'Distribution', {
  domainNames: ['example.com'],
});

new CrossAccountRoute53RecordSet(this, 'ARecord', {
  delegationRoleName: 'WebRoute53Role',
  delegationRoleAccount: '111111111', // The account that contains the zone and role
  hostedZoneId,
  resourceRecordSets: [{
    Name: `example.com`,
    Type: 'A',
    AliasTarget: {
      DNSName: distribution.distributionDomainName,
      HostedZoneId: 'Z2FDTNDATAQYW2', // Cloudfront Hosted Zone Id
      EvaluateTargetHealth: false,
    },
  }],
});
