Introduction:-
Route53 is #Amazon’s DNS web service that can be used to route traffic to Internet resources such as #EC2 instances, S3 buckets, or even other domain names. In this blog, we will deploy a #Route53 hosted zone using Terraform. #Terraform is an open-source #infrastructure as code (IAC) tool that allows you to define and provision infrastructure safely and efficiently.
Prerequisites:
AWS account
IAM User with Route53 access
Step 1: Setting up the Terraform Environment The first step is to set up the #Terraform environment on your local machine. You can follow the official Terraform installation guide to install #Terraform on your machine. Once you have installed Terraform, create a new directory for your project and create three files: main.tf, variables.tf, and outputs.tf.
Step 2: Defining the Route53 Hosted Zone In this step, we will define the Route53 hosted zone using the main.tf file. Open the main.tf file and add the following code:
provider "aws" {
region = "us-east-1"
}
resource "aws_route53_zone" "myzone" {
name = "${var.domain_name}"
comment = "${var.comment}"
}
Here, we have defined the provider as aws with the region as us-east-1. We have also defined a aws_route53_zone resource with the name of the hosted zone and the optional comment field.
Step 3: Defining the Variables In this step, we will define the variables we will use in our main.tf file. Open the variables.tf file and add the following code:
variable "domain_name" {
default = "my-zone"
description = "The domain name to use for the Route53 Hosted Zone"
}
variable "comment" {
default = "Hosted-zone"
description = "A comment for the Route53 Hosted Zone"
}
Here, we have defined two variables: domain_name and comment. The domain_name variable will be used to define the name of our Route53 hosted zone. The comment variable is an optional field that allows you to add a comment to the hosted zone.
Step 4: Adding Outputs In this step, we will add an output to display the name of the hosted zone that we just created. Open the outputs.tf file and add the following code:
output "hosted_zone_name" {
value = "${aws_route53_zone.myzone.name}"
}
Step 5: Running the #Terraform Commands Now that we have defined our variables, resources, and outputs, we can initialize and run our Terraform commands. Open your terminal, navigate to your project directory and run the following commands:
$ terraform init
$ terraform plan
$ terraform apply
The terraform init command will initialize our Terraform environment. The terraform plan command will show us the plan of the changes to be made. The terraform apply command will apply those changes and create the Route53 hosted zone.
Step 6: Verifying the Deployment Once the terraform apply command has completed, you can go to your #AWS console and verify that the #Route53 hosted zone has been created. You can also verify this by running the following command:
$ terraform show
This command will display the current state of your infrastructure.
Conclusion:-
In this blog, we have deployed a #Route53 hosted zone using #Terraform.deploying a Route 53 hosted zone using Terraform provides a streamlined and automated approach to managing DNS configurations within your AWS environment. By following the steps outlined in this guide, you have learned how to leverage Terraform to deploy a #Route 53 hosted zone efficiently.
#Route 53 hosted zones are essential for managing #DNS records, domain names, and routing traffic to your resources. With #Terraform, you can define and manage your hosted zone as code, enabling version control, repeatability, and easy collaboration within your infrastructure-as-code workflow.
