Introduction :-

In the ever-evolving landscape of cloud infrastructure, efficient DNS management is paramount for robust web applications. Amazon Route 53, a scalable and highly available Domain Name System (DNS) web service, is a go-to solution for many businesses hosted on AWS. This guide aims to demystify the process of deploying a Route 53 Hosted Zone using Terraform, providing a simplified yet comprehensive approach for users to enhance their DNS infrastructure.

Pre-requestites :-

• Terragrunt Should be installed.

• An Aws account with Route-53 Access.

Steps for deploying Route-53 hosted zone using Terragrunt --

Note:- Before starting the Deployment, Login to your Aws account and create a s3 bucket and Dynamo-Db table.

1. Create a folder with name route53 & a file called terragrunt-s3.hcl and with in the route53 folder create one more folder called zone. Also create a file called terragrunt.hcl in the zone folder.

2. Copy and paste the below code into terragrunt-s3.hcl file

remote_state {
  backend = "s3"
  generate = {
    path      = "_backend.tf"
    if_exists = "overwrite_terragrunt"
  }
  config = {
    key            = "terragrunt/route53/terraform.tfstate"
    region         = "YOUR REGION"
     encrypt       = true
    bucket         = "YOUR BACKEND_S3-BUCKET NAME"
    dynamodb_table = "YOUR DYNAMO_DB TABLE NAME"
  }
}

3. Copy the below code into your terragrunt.hcl file located in zone folder.

terraform {
  source = "tfr:///terraform-aws-modules/route53/aws//modules/zones?version=2.10.1"
}
include "root" {
 path = find_in_parent_folders()
}

locals {
  region      = "us-east-1"
}

inputs = {
  region = "us-east-1"
  zones = {
    "dev.mahiratechnology.com" = {
      comment = "mahiratechnology Domain"
      tags = {
      Name = "test.mahiratechnology.com"
    }
    }
  }
}

• Replace the values of Dynamo-Db table and S3 bucket name with your values.

4. Open a terminal window and locate to route53 folder. Now configure your aws credentials and run terragrunt init command. Once the Initilization is done, run terragrunt plan, after the plan is done, then run the terragrunt apply command to deploy your resources on aws.

Conclusion:-

In conclusion, deploying a Route 53 Hosted Zone using Terraform is a strategic move towards achieving a more streamlined and automated DNS management system. By embracing Infrastructure as Code, users gain the ability to version-control their DNS configurations, maintain consistency across environments, and easily scale their infrastructure as their applications grow.
