How Do I Build an AWS Apigateway Domainname With Pulumi?

In this guide, we will build an AWS API Gateway domain name in TypeScript with Pulumi. We will cover the key services involved, provide a step-by-step explanation, highlight key points, and conclude with a summary.

Introduction

In this solution, we will use Pulumi to create an AWS API Gateway domain name. The key services involved are AWS API Gateway, AWS Route 53, and AWS Certificate Manager (ACM). AWS API Gateway allows us to create, publish, maintain, monitor, and secure APIs. AWS Route 53 is a scalable and highly available Domain Name System (DNS) web service. AWS Certificate Manager (ACM) handles the complexity of creating and managing SSL/TLS certificates.

Step-by-Step Explanation

Step 1: Set up Pulumi and AWS Provider

First, we need to set up Pulumi and configure the AWS provider. This involves installing Pulumi, setting up a new Pulumi project, and configuring AWS credentials.

Step 2: Create an ACM Certificate

Next, we will create an ACM certificate for the custom domain name. This certificate will be used to secure the API Gateway domain name.

Step 3: Create a Route 53 Hosted Zone

We will create a Route 53 hosted zone for the custom domain. This hosted zone will manage the DNS records for the domain.

Step 4: Create an API Gateway Domain Name

We will create an API Gateway domain name and associate it with the ACM certificate and Route 53 hosted zone.

Step 5: Create a DNS Record in Route 53

Finally, we will create a DNS record in Route 53 to map the custom domain name to the API Gateway domain name.

Key Points

• Pulumi allows us to use familiar programming languages to define and manage cloud infrastructure.
• AWS API Gateway, Route 53, and ACM are the key services involved in creating a custom domain name for an API.
• Proper configuration of AWS credentials and Pulumi project setup is essential for successful deployment.
• ACM certificates are required to secure custom domain names in API Gateway.
• Route 53 hosted zones and DNS records are used to manage and map custom domain names.

Conclusion

In this guide, we demonstrated how to build an AWS API Gateway domain name using TypeScript with Pulumi. We covered the key services involved, provided a step-by-step explanation, highlighted key points, and concluded with a summary. By following these steps, you can successfully create and manage custom domain names for your APIs using Pulumi and AWS services.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create an ACM certificate
const certificate = new aws.acm.Certificate("certificate", {
    domainName: "example.com",
    validationMethod: "DNS",
});

// Create a Route 53 hosted zone
const zone = new aws.route53.Zone("zone", {
    name: "example.com",
});

// Create an API Gateway REST API
const api = new aws.apigateway.RestApi("api", {
    name: "my-api",
});

// Create an API Gateway domain name
const domainName = new aws.apigateway.DomainName("domainName", {
    domainName: "api.example.com",
    certificateArn: certificate.arn,
});

// Create a DNS record in Route 53
const record = new aws.route53.Record("record", {
    zoneId: zone.zoneId,
    name: domainName.domainName,
    type: "A",
    aliases: [{
        name: domainName.cloudfrontDomainName,
        zoneId: domainName.cloudfrontZoneId,
        evaluateTargetHealth: true,
    }],
});

export const certificateArn = certificate.arn;
export const zoneId = zone.zoneId;
export const domainNameOutput = domainName.domainName;
export const recordName = record.name;
