Overview

This AWS Solutions Construct implements an Amazon Route 53 connected to a configured Amazon API Gateway REST API.

Here is a minimal deployable pattern definition in Typescript:

import * as api from '@aws-cdk/aws-apigateway';
import * as lambda from "@aws-cdk/aws-lambda";
import * as route53 from "@aws-cdk/aws-route53";
import { Route53ToApigateway } from '@aws-solutions-constructs/aws-route53-apigateway';

// The construct requires an existing REST API, this can be created in raw CDK or extracted
// from a previously instantiated construct that created an API Gateway REST API
const existingRestApi = previouslyCreatedApigatewayToLambdaConstruct.apiGateway;

const ourHostedZone = route53.HostedZone.fromLookup(this, 'HostedZone', {
    domainName: "example.com",
  });

const certificate = acm.Certificate.fromCertificateArn(
    stack,
    "fake-cert",
    "arn:aws:acm:us-east-1:123456789012:certificate/11112222-3333-1234-1234-123456789012"
  );

// This construct can only be attached to a configured API Gateway.
new Route53ToApigateway(this, 'Route53ToApigatewayPattern', {
    existingApiGatewayObj: existingRestApi,
    existingHostedZoneInterface: ourHostedZone,
    publicApi: true,
    existingCertificateInterface: certificate
});

Initializer

new Route53ToApigateway(scope: Construct, id: string, props: Route53ToApigatewayProps);

Parameters

• scope Construct
• id string
• props Route53ToApigatewayProps

Pattern Construct Props

This construct cannot create a new Public Hosted Zone, if you are creating a public API you must supply an existing Public Hosted Zone that will be reconfigured with a new Alias record. Public Hosted Zones are configured with public domain names and are not well suited to be launched and torn down dynamically, so this construct will only reconfigure existing Public Hosted Zones.

This construct can create Private Hosted Zones. If you want a Private Hosted Zone, then you can either provide an existing Private Hosted Zone or a privateHostedZoneProps value with at least the Domain Name defined. If you are using privateHostedZoneProps, an existing wildcard certificate (*.example.com) must be issued from a previous domain to be used in the newly created Private Hosted Zone. New certificate creation and validation do not take place in this construct. A private Rest API already exists in a VPC, so that VPC must be provided in the existingVpc prop. There is no scenario where this construct can create a new VPC (since it can't create a new API), so the vpcProps property is not supported on this construct.

Name	Type	Description
publicApi	boolean	Whether the construct is deploying a private or public API. This has implications for the Hosted Zone and VPC.
privateHostedZoneProps?	route53.PrivateHostedZoneProps	Optional custom properties for a new Private Hosted Zone. Cannot be specified for a public API. Cannot specify a VPC, it will use the VPC in existingVpc or the VPC created by the construct. Providing both this and existingHostedZoneInterface is an error.
existingHostedZoneInterface?	route53.IHostedZone	Existing Public or Private Hosted Zone (type must match publicApi setting). Specifying both this and privateHostedZoneProps is an error. If this is a Private Hosted Zone, the associated VPC must be provided as the existingVpc property.
existingVpc?	ec2.IVpc	An existing VPC in which to deploy the construct.
existingApiGatewayInterface	api.IRestApi	The existing API Gateway instance that will be connected to the Route 53 hosted zone. Note that Route 53 can only be connected to a configured API Gateway, so this construct only accepts an existing IRestApi and does not accept apiGatewayProps.
existingCertificateInterface	certificatemanager.ICertificate	An existing AWS Certificate Manager certificate for your custom domain name.

Pattern Properties

Name	Type	Description
hostedZone	route53.IHostedZone	The hosted zone used by the construct (whether created by the construct or provided by the client)
vpc?	ec2.IVpc	The VPC used by the construct.
apiGateway	api.RestApi	Returns an instance of the API Gateway REST API created by the pattern.
certificate	certificatemanager.ICertificate	THe certificate used by the construct (whether create by the construct or provided by the client)

Default settings

Out of the box implementation of the Construct without any override will set the following defaults:

Amazon Route53

• Adds an ALIAS record to the new or provided Hosted Zone that routes to the construct's API Gateway

Amazon API Gateway

• User provided API Gateway object is used as-is
• Sets up custom domain name mapping to API
