# Create the subdomain and a test record
resource "random_id" "suffix" {
  byte_length = 2
}

locals {
  sub_domain = "${var.sub_domain}-${random_id.suffix.dec}"
}

module "subdomain" {
  source             = "./.."
  cloudflare_zone_id = var.cloudflare_zone_id
  cloudflare_domain  = var.cloudflare_domain
  sub_domain         = local.sub_domain
  ttl                = 135
}

locals {
  test_hostname = "test.${module.subdomain.dns_name}"
