Add datasource of SOA type records

[uanid]

Terraform CLI and Provider Versions

Terraform v1.2.9
on darwin_amd64
+ provider registry.terraform.io/hashicorp/dns v3.2.4

Use Cases or Problem Statement

The TTL of SOA record means NX_DOMAIN and NO_DATA's cache time.

Let's tell about one scenario, that register or delete domains dynamically,
A bunch of servers lookup domains in rapidly and periodically.

If the TTL of SOA is high like below picture, the servers are failed long times cause NX_DOMAINS time is too high.

The record means when NX_DOMAIN respond, cache it 30 hours

Proposal

I'm manage 110 hosted zones, among them 80 zones are dynamically managed.

I want read and update SOA record by dns soa record datasource.

This proposal add new datasource dns_soa_record_set

Input

data "dns_soa_record_set" "amazon" {
  host = "amazon.com"
}

Output

mname: dns-external-master.amazon.com. 
rname: root.amazon.com.
serial: 2010167466
refresh: 180
retry: 60
expire: 3024000
ttl: 60
raw: dns-external-master.amazon.com. root.amazon.com. 2010167466 180 60 3024000 60

How much impact is this issue causing?

The module I just published will let you do exactly this (i.e. get the SOA record for amazon.com). It doesn't support normal dns-wire-format messages though, so you need to query a DNS server that provides a DNS-over-HTTPS JSON API (e.g. like that provided by Google, Cloudflare, Alibaba, NextDNS etc)

Example:

• Use Cloudflare to lookup Amazon's SOA record

  module "http-json" {
    source             = "cunneen/http-json/dns"
    name               = "amazon.com"
    type               = "SOA"
    endpoint           = "https://cloudflare-dns.com/dns-query"
    headers = {
      accept = "application/dns-json"
    }
  }
