Module: route53-alias

Terraform module that implements "vanity" host names (e.g. brand.com) as ALIAS records to another Route53 DNS resource record (e.g. ELB/ALB, S3 Bucket Endpoint or CloudFront Distribution). Unlike CNAME records, the synthetic ALIAS record works with zone apexes.

Usage​

This will define a A resource record for www.example.com as an alias of the aws_elb.example.dns_name.

module "production_www" {
  source = "cloudposse/route53-alias/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version     = "x.x.x"
  aliases         = ["www.example.com.", "static1.cdn.example.com.", "static2.cdn.example.com"]
  parent_zone_id  = var.parent_zone_id
  target_dns_name = aws_elb.example.dns_name
  target_zone_id  = aws_elb.example.zone_id
}
