Empty output:
masters = toset([])

Important Factoids

API allows getting name servers for a public zone:

@kbechler as I can see description in hc doc

Master DNS servers, from which the slave servers get DNS information
This parameter is not used currently.

nameserver is another attribute

[outcatcher]

I suppose, as there is masters attribute in API documentation (not working), it's better to use name_servers attribute or dedicated data source for getting list of the name servers for the zone with the following API: https://docs.otc.t-systems.com/en-us/api/dns/dns_api_62004.html

@kbechler We might return a list of nameservers? But in this case, there may be not only master servers.
Will this be acceptable for you?

[kbechler]

@vladimirvshivkov My goal is to automate the process of adding new zone. If it will be a valid list of nameservers that could be used to configure NS delegation in parent zone, if will be acceptable for me.

On the other hand, maybe such variable should be called "nameservers", not "masters" as the latter one would be confusing.

Implementing as masters requires API changes

@kbechler
We released a new version with DNS nameservers data source.

try to use this config:

terraform {
  required_version = ">= 0.15.0, < 2.0"
  required_providers {
    opentelekomcloud = {
      source  = "opentelekomcloud/opentelekomcloud"
      version = "= 1.29.2"
    }
  }
}

provider "opentelekomcloud" {
  tenant_name = "eu-de"
  auth_url    = "https://iam.eu-de.otc.t-systems.com/v3"
}

resource "opentelekomcloud_dns_zone_v2" "zone_1" {
  name        = "test-zone-1.com."
  email       = "email1@example.com"
  description = "a public zone"
  ttl         = 3000
  type        = "public"
}

data "opentelekomcloud_dns_nameservers_v2" "nameservers" {
  zone_id = opentelekomcloud_dns_zone_v2.zone_1.id
}

output "masters" { value = data.opentelekomcloud_dns_nameservers_v2.nameservers }

this outputs the following:

masters = {
  "id" = "ns1.open-telekom-cloud.com."
  "nameservers" = tolist([
    {
      "hostname" = "ns1.open-telekom-cloud.com."
      "priority" = 1
    },
    {
      "hostname" = "ns2.open-telekom-cloud.com."
      "priority" = 2
    },
  ])
  "zone_id" = "ff80808275f5fc0f01806ba10ea62b11"
}

Can't wait for your feedback!
