Terraform Route53 Configuration.

TODO: collapasable, copyable, download, etc

What is the terraform for setting up a route53 domain for example.com?To set up a Route 53 domain for example.com using Terraform, you need to create a Terraform configuration file (e.g., main.tf) with the necessary resources. Here's an example of how to do this:

1. First, ensure that you have Terraform installed and the AWS CLI configured with the necessary credentials.

2. Create a Terraform configuration file (main.tf) and include the following content:

provider "aws" {
  region = "us-west-2"
}

resource "aws_route53_zone" "example" {
  name = "example.com"
}

resource "aws_route53_record" "example_ns" {
  zone_id = aws_route53_zone.example.zone_id
  name    = "example.com"
  type    = "NS"
  ttl     = "86400"

  records = aws_route53_zone.example.name_servers
}

resource "aws_route53_record" "example_a" {
  zone_id = aws_route53_zone.example.zone_id
  name    = "example.com"
  type    = "A"
  ttl     = "300"
  records = ["YOUR_IPV4_ADDRESS"]
}

output "name_servers" {
  value = aws_route53_zone.example.name_servers
}

Replace "YOUR_IPV4_ADDRESS" with the IPv4 address of your web server or the resource you want to route traffic to.

3. Initialize Terraform by running terraform init in the same directory as your main.tf file.

4. Preview the changes to be made by running terraform plan.

5. Apply the changes by running terraform apply. Confirm the changes by typing yes when prompted.

After the Terraform execution is completed, the example.com domain will be set up on Route 53, along with an A record pointing to your specified IP address. The name server (NS) records will also be created automatically.

Remember to update your domain registrar with the name servers output by Terraform to delegate DNS management to Route 53.

Please note that this example does not cover the actual domain registration process. To register a domain with AWS, you can use the aws_route53_domain resource in your Terraform configuration or register it manually through the AWS Management Console.Can you generate terraform configuration from your existing aws route53 ?Yes, you can generate Terraform configuration from your existing AWS Route 53 setup using a tool called Terraformer. Terraformer is an open-source tool developed by Google that allows you to reverse engineer cloud resources into Terraform configurations.

Here are the steps to generate Terraform configuration from your existing AWS Route 53 setup:

1. Install Terraformer:

For macOS, you can use Homebrew:

brew install terraformer

For Linux, you can download the latest release from the GitHub repository:

wget https://github.com/GoogleCloudPlatform/terraformer/releases/download/$(curl --silent https://api.github.com/repos/GoogleCloudPlatform/terraformer/releases/latest | grep -oP '"tag_name": "\K(.*)(?=")')/terraformer-linux-amd64
chmod +x terraformer-linux-amd64
sudo mv terraformer-linux-amd64 /usr/local/bin/terraformer

For other platforms and installation methods, check the official documentation: https://github.com/GoogleCloudPlatform/terraformer/blob/master/docs/install.md

2. Ensure that you have the AWS CLI installed and configured with the necessary credentials.

3. Run Terraformer to import your Route 53 configuration:

terraformer import aws --resources=route53 --regions=us-west-2 --profile=<your_aws_profile> --path-output=<output_directory>

Replace <your_aws_profile> with your AWS CLI profile name, and <output_directory> with the desired output directory for the Terraform configuration files.

4. Terraformer will generate a set of .tf files in the specified output directory. Review the generated files and organize them as needed. You may also need to make some adjustments, such as removing any sensitive data, adding variables, or cleaning up the code.

5. After organizing the generated files, run terraform init in the directory with the .tf files to initialize Terraform.

6. Use terraform plan to preview the changes. Since the configuration is generated from the existing infrastructure, there should be no changes to apply.

7. You can now manage your existing Route 53 setup using the generated Terraform configuration.

Please note that Terraformer may not always generate perfect Terraform configurations, and some manual adjustments might be needed. Always review and test the generated configurations thoroughly before using them in production environments.
