The CDK Construct Library for AWS::Route53

Amazon Route53 Construct Library

To add a public hosted zone:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_route53 as route53

route53.PublicHostedZone(self, "HostedZone",
    zone_name="fully.qualified.domain.com"
)

To add a private hosted zone, use PrivateHostedZone. Note that enableDnsHostnames and enableDnsSupport must have been enabled for the VPC you're configuring for private hosted zones.

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_ec2 as ec2
import aws_cdk.aws_route53 as route53

vpc = ec2.Vpc(self, "VPC")

zone = route53.PrivateHostedZone(self, "HostedZone",
    zone_name="fully.qualified.domain.com",
    vpc=vpc
)

Additional VPCs can be added with zone.addVpc().

Adding Records

To add a TXT record to your zone:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_route53 as route53

route53.TxtRecord(self, "TXTRecord",
    zone=my_zone,
    record_name="_foo", # If the name ends with a ".", it will be used as-is;
    # if it ends with a "." followed by the zone name, a trailing "." will be added automatically;
    # otherwise, a ".", the zone name, and a trailing "." will be added automatically.
    # Defaults to zone root if not specified.
    values=["Bar!", "Baz?"],
    ttl=Duration.minutes(90)
)

To add a A record to your zone:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_route53 as route53

route53.ARecord(self, "ARecord",
    zone=my_zone,
    target=route53.RecordTarget.from_ip_addresses("1.2.3.4", "5.6.7.8")
)

To add a AAAA record pointing to a CloudFront distribution:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_route53 as route53
import aws_cdk.aws_route53_targets as targets

route53.AaaaRecord(self, "Alias",
    zone=my_zone,
    target=route53.RecordTarget.from_alias(targets.CloudFrontTarget(distribution))
)

Constructs are available for A, AAAA, CAA, CNAME, MX, NS, SRV and TXT records.

Use the CaaAmazonRecord construct to easily restrict certificate authorities allowed to issue certificates for a domain to Amazon only.

Imports

If you don't know the ID of the Hosted Zone to import, you can use the HostedZone.fromLookup:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
HostedZone.from_lookup(self, "MyZone",
    domain_name="example.com"
)

HostedZone.fromLookup requires an environment to be configured. Check out the documentation for more documentation and examples. CDK automatically looks into your ~/.aws/config file for the [default] profile. If you want to specify a different account run cdk deploy --profile [profile].

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
MyDevStack(app, "dev",
    env={
        "account": process.env.CDK_DEFAULT_ACCOUNT,
        "region": process.env.CDK_DEFAULT_REGION
    }
)

If you know the ID and Name of a Hosted Zone, you can import it directly:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
zone = HostedZone.from_hosted_zone_attributes(self, "MyZone",
    zone_name="example.com",
    hosted_zone_id="ZOJJZC49E0EPZ"
)

Alternatively, use the HostedZone.fromHostedZoneId to import hosted zones if you know the ID and the retrieval for the zoneName is undesirable.

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
zone = HostedZone.from_hosted_zone_id(self, "MyZone",
    hosted_zone_id="ZOJJZC49E0EPZ"
)

VPC Endpoint Service Private DNS

When you create a VPC endpoint service, AWS generates endpoint-specific DNS hostnames that consumers use to communicate with the service. For example, vpce-1234-abcdev-us-east-1.vpce-svc-123345.us-east-1.vpce.amazonaws.com. By default, your consumers access the service with that DNS name. This can cause problems with HTTPS traffic because the DNS will not match the backend certificate:

curl: (60) SSL: no alternative certificate subject name matches target host name 'vpce-abcdefghijklmnopq-rstuvwx.vpce-svc-abcdefghijklmnopq.us-east-1.vpce.amazonaws.com'

Effectively, the endpoint appears untrustworthy. To mitigate this, clients have to create an alias for this DNS name in Route53.

Private DNS for an endpoint service lets you configure a private DNS name so consumers can access the service using an existing DNS name without creating this Route53 DNS alias This DNS name can also be guaranteed to match up with the backend certificate.

Before consumers can use the private DNS name, you must verify that you have control of the domain/subdomain.

Assuming your account has ownership of the particlar domain/subdomain, this construct sets up the private DNS configuration on the endpoint service, creates all the necessary Route53 entries, and verifies domain ownership.

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
from aws_cdk.core import Stack
from aws_cdk.aws_ec2 import Vpc, VpcEndpointService
from aws_cdk.aws_elasticloadbalancingv2 import NetworkLoadBalancer
from aws_cdk.aws_route53 import PublicHostedZone

stack = Stack()
vpc = Vpc(stack, "VPC")
nlb = NetworkLoadBalancer(stack, "NLB",
    vpc=vpc
)
vpces = VpcEndpointService(stack, "VPCES",
    vpc_endpoint_service_load_balancers=[nlb]
)
# You must use a public hosted zone so domain ownership can be verified
zone = PublicHostedZone(stack, "PHZ",
    zone_name="aws-cdk.dev"
)
VpcEndpointServiceDomainName(stack, "EndpointDomain",
    endpoint_service=vpces,
    domain_name="my-stuff.aws-cdk.dev",
    public_hosted_zone=zone
)
