How Do I Create an Cname Record in AWS Route 53?

Introduction

In this guide, we will demonstrate how to create a CNAME record in AWS Route 53 using Pulumi with TypeScript. Pulumi is an Infrastructure as Code (IaC) tool that allows you to define and manage cloud resources using familiar programming languages. AWS Route 53 is a scalable and highly available Domain Name System (DNS) web service designed to route end users to internet applications.

Step-by-Step Explanation

Step 1: Install Pulumi and AWS SDK

First, ensure that you have Pulumi and the AWS SDK installed. You can install Pulumi using npm:

npm install -g pulumi

Next, install the Pulumi AWS package:

npm install @pulumi/aws

Step 2: Create a New Pulumi Project

Create a new Pulumi project by running the following command and following the prompts:

pulumi new aws-typescript

Step 3: Define the CNAME Record

In your project’s index.ts file, define the CNAME record using the aws.route53.Record resource. You will need to specify the hosted zone ID, the name of the record, and the value it should point to.

Step 4: Configure AWS Credentials

Ensure that your AWS credentials are configured. You can do this by setting the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables or by using the AWS CLI to configure your credentials.

Step 5: Deploy the Stack

Finally, deploy your Pulumi stack by running:

pulumi up

This will create the CNAME record in AWS Route 53.

Key Points

• Pulumi allows you to define and manage cloud resources using familiar programming languages.
• AWS Route 53 is a scalable and highly available DNS web service.
• You need to install Pulumi and the AWS SDK to get started.
• Define the CNAME record in your Pulumi project’s index.ts file.
• Ensure your AWS credentials are configured before deploying the stack.

Conclusion

In this guide, we demonstrated how to create a CNAME record in AWS Route 53 using Pulumi with TypeScript. By following the steps outlined above, you can easily manage your DNS records using Pulumi’s Infrastructure as Code approach. This method provides a more flexible and maintainable way to handle your cloud resources.

Full Code Example

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

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

// Create a CNAME record
const cnameRecord = new aws.route53.Record("exampleCnameRecord", {
    zoneId: hostedZone.zoneId,
    name: "www.example.com",
    type: "CNAME",
    ttl: 300,
    records: ["example.com"],
});

export const cnameRecordFqdn = cnameRecord.fqdn;
