We can create a template for RecordSet, given as follows:

1. Start the template with the template version and a description (optional).
2. Define the parameters (of the string type) for the root domain name, the sub-domain name, and the S3 hosted zone ID.

Note that the S3 hosted zone is static, based on the region (for example, Z2FDTNDATAQYW2 for ap-south-1).

3. Define a resource of the type RecordSetGroup type to add A records for the domains:

Resources:
  QuizzerCloudDNS:
    Type: AWS::Route53::RecordSetGroup
    Properties:
      HostedZoneName: !Sub
        - ${DomainName}.
        - DomainName: !Ref RootDomainName
      Comment: Zone apex alias.
      RecordSets:
      -
        Name: !Ref RootDomainName
        Type: A
        AliasTarget:
          HostedZoneId: !Ref RecordHostedZoneId
          DNSName: !ImportValue CloudFrontDomainName
      -
        Name: !Ref SubDomainName
        Type: A
        AliasTarget:
          HostedZoneId: !Ref RecordHostedZoneId
          DNSName: !ImportValue CloudFrontDomainName

The HostedZoneName is the domain name, followed by a dot (.), and the RecordHostedZone ID is a constant value for all of the CloudFront distributions

4. Define an Outputs section to return the URLs (optional).
5. Execute the aws cloudformation create-stack by passing the parameters, and then verify the following:

After executing the create-stack sub-command, check the status by using the describe-stacks sub-command. Once it is successful, it should return a response with the following Outputs section:

We can verify that everything worked by going to quizzercloud.com and www.quizzercloud.com in a browser, as shown in the following screenshot:

Note that the URL is not secure. Even if we use HTTPS, we will still get a Not Secure message, as we do not have a valid certificate for this domain. We will look at how to fix this in the next recipe.
