How Do I Create an AWS Route53 Record Using Pulumi?

Introduction

Creating DNS records in AWS Route53 can be efficiently managed using Pulumi, an infrastructure as code tool. This guide will walk you through the process of setting up a Route53 hosted zone and adding a DNS record using Pulumi in TypeScript.

Step-by-Step Process

To create an AWS Route53 record using Pulumi, follow these steps:

1. Import Required Modules: Start by importing the Pulumi and AWS modules necessary for the setup.

2. Create a Route53 Hosted Zone: Define a new hosted zone that will serve as a container for your DNS records.

3. Add a DNS Record: Within the hosted zone, create a DNS record. This example demonstrates creating an A record pointing to a specific IP address.

4. Export Name Servers: Finally, export the name servers of the hosted zone for reference or further configuration.

Below is the Pulumi program illustrating these steps:

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

// Create a new Route53 hosted zone
const zone = new aws.route53.Zone("exampleZone", {
    name: "example.com",
});

// Create a new A record in the hosted zone
const record = new aws.route53.Record("exampleRecord", {
    zoneId: zone.id,
    name: "www.example.com",
    type: "A",
    ttl: 300,
    records: ["192.0.2.1"],
});

// Export the name servers for the hosted zone
export const nameServers = zone.nameServers;

Key Points

• Modules: The program imports Pulumi and AWS modules to manage AWS resources.
• Hosted Zone: A new hosted zone named exampleZone is created for the domain example.com.
• DNS Record: An A record exampleRecord is added, pointing to IP address 192.0.2.1 with a TTL of 300 seconds.
• Name Servers: The name servers of the hosted zone are exported for external use.

Conclusion

This guide has demonstrated how to set up a basic DNS configuration in AWS Route53 using Pulumi. By following these steps, you can create and manage DNS records programmatically, allowing for scalable and repeatable infrastructure deployment. This setup can be further customized with additional records and configurations to suit your needs.
