How to Add Records to a Public Hosted Zone in AWS Route 53?

In this guide, we will demonstrate how to add records to a public hosted zone in AWS Route 53 using Pulumi in TypeScript. We will cover the key services involved, provide a step-by-step explanation of the process, highlight key points to remember, and conclude with a summary of the solution.

Introduction

In this solution, we will use Pulumi, an Infrastructure as Code (IaC) tool, to manage AWS resources. Specifically, we will focus on adding records to a public hosted zone in AWS Route 53. AWS Route 53 is a scalable and highly available Domain Name System (DNS) web service designed to route end users to internet applications. Pulumi allows us to define, deploy, and manage cloud infrastructure using familiar programming languages like TypeScript.

Step-by-Step Explanation

Step 1: Set Up Pulumi Project

First, we need to set up a new Pulumi project. Initialize a new Pulumi project by running the following command in your terminal:

pulumi new aws-typescript

Step 2: Install AWS Pulumi Package

Next, install the AWS Pulumi package to interact with AWS services:

npm install @pulumi/aws

Step 3: Import Required Modules

In your index.ts file, import the necessary Pulumi and AWS modules:

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

Step 4: Create a Public Hosted Zone

Create a new public hosted zone in Route 53:

const hostedZone = new aws.route53.Zone("myHostedZone", {
  name: "example.com",
});

Step 5: Add Records to the Hosted Zone

Add records to the hosted zone, such as A, CNAME, and MX records:

const aRecord = new aws.route53.Record("aRecord", {
  zoneId: hostedZone.zoneId,
  name: "www",
  type: "A",
  ttl: 300,
  records: ["192.0.2.1"],
});

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

const mxRecord = new aws.route53.Record("mxRecord", {
  zoneId: hostedZone.zoneId,
  name: "",
  type: "MX",
  ttl: 300,
  records: ["10 mail.example.com"],
});

Key Points

• Pulumi: An Infrastructure as Code tool that allows you to define, deploy, and manage cloud infrastructure using programming languages.
• AWS Route 53: A scalable and highly available DNS web service designed to route end users to internet applications.
• Hosted Zone: A container for DNS records for a specific domain.
• DNS Records: Entries in a DNS database that provide information about a domain, such as IP addresses (A records), aliases (CNAME records), and mail servers (MX records).

Conclusion

In this guide, we demonstrated how to add records to a public hosted zone in AWS Route 53 using Pulumi in TypeScript. We covered the key services involved, provided a step-by-step explanation of the process, highlighted key points to remember, and concluded with a summary of the solution. By using Pulumi, you can manage your cloud infrastructure more efficiently and with greater flexibility.

Full Code Example

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

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

// Add an A record to the hosted zone
const aRecord = new aws.route53.Record("aRecord", {
    zoneId: hostedZone.zoneId,
    name: "www",
    type: "A",
    ttl: 300,
    records: ["192.0.2.1"],
});

// Add a CNAME record to the hosted zone
const cnameRecord = new aws.route53.Record("cnameRecord", {
    zoneId: hostedZone.zoneId,
    name: "blog",
    type: "CNAME",
    ttl: 300,
    records: ["example.com"],
});

// Add an MX record to the hosted zone
const mxRecord = new aws.route53.Record("mxRecord", {
    zoneId: hostedZone.zoneId,
    name: "",
    type: "MX",
    ttl: 300,
    records: ["10 mail.example.com"],
});

// Export the hosted zone ID and record FQDNs
export const hostedZoneId = hostedZone.zoneId;
export const aRecordFqdn = aRecord.fqdn;
export const cnameRecordFqdn = cnameRecord.fqdn;
export const mxRecordFqdn = mxRecord.fqdn;
