sys-svc-dns

Bootstrap and maintain DNS prerequisites for your web stack on Cloudflare.

This role validates credentials and (by default) ensures:

  • A (and optional AAAA) records on the apex (@) for all base SLD domains
  • Wildcard A/AAAA records (*.parent) for parent hosts via sys-dns-wildcards
  • (Optional) CAA records for Let’s Encrypt (kept as a commented block you can re-enable)

Runs once per play and is safe to include in stacks that roll out many domains.

What it does

  1. Validate CLOUDFLARE_API_TOKEN is present (early fail if missing).
  2. Ensure apex A/AAAA exist for every base SLD in SYS_SVC_DNS_BASE_DOMAINS:
    • Writes @ A → networks.internet.ip4
    • Writes @ AAAA → networks.internet.ip6 (only if global and present)
  3. (Optional) CAA records for all base SLDs (commented in the tasks; enable if you want CAA managed here).
  4. Ensure wildcard parent DNS exists (*.parent derived from children):
    • Delegates to sys-dns-wildcards
    • Creates A (and AAAA if enabled) wildcard records on the Cloudflare zone, optionally proxied.

Parent hosts example:
c.wiki.example.com → parent wiki.example.com (plus example.com apex)
