How can I create an SRV record with the UltraDNS or PowerDNS provider in Terraform?

WARNING: The UltraDNS API will try to "help" you by placing the ending "." on the name. This will cause Terraform to think there are changes every time you plan or apply.

PowerDNS:

locals {
  sorted_pdns_hostnames = "${sort(module.server.hostnames)}"
  records               = "${formatlist("10 10 80 %s.${var.vpc}.${var.region}.private.", local.sorted_pdns_hostnames)}"
}

resource "powerdns_record" "pool" {
  zone    = "${var.pdns_zone}"
  name    = "${var.pdns_name}"
  type    = "SRV"
  ttl     = 300
  records = ["${local.records}"]
}

UltraDNS:

locals {
  sorted_hostnames = "${sort(module.server.hostnames)}"
  rdata            = "${formatlist("10 10 80 %s.${var.vpc}.${var.region}.private.", local.sorted_hostnames)}"
}

resource "ultradns_record" "pool" {
  zone  = "${var.zone_domain}"
  name  = "${var.ultradns_record_name}"
  rdata = ["${local.rdata}"]
  type  = "SRV"
  ttl   = 300
}
