Documentation

azure-dns-zone

Azure public DNS zone (azurerm_dns_zone) plus a clean, map-driven set of record sets — A, AAAA, CNAME, TXT, MX, NS, CAA and SRV. Works with Terraform and OpenTofu (>= 1.6), azurerm provider >= 4.0, < 5.0. The module consumes an existing resource group (DNS zones are global, so there is no location to set).

Each record type maps to its own azurerm resource via for_each, so addressing is stable and editing one entry never churns the others. The fiddly Azure-isms are handled or documented for you:

  • Record names are relative to the zone — use "@" (the default) for the apex or a label like "www"; never a full FQDN.
  • TXT values are verbatim — no escaped quoting; Azure handles the 255-char segmentation (this differs from Route 53).
  • CNAME-at-apex and apex-NS overrides are rejected at plan time (DNS forbids the former; Azure manages the latter).

Requirements

RequirementVersion
Terraform / OpenTofu>= 1.6
hashicorp/azurerm>= 4.0, < 5.0

Security notes

  • An azurerm_dns_zone is a public zone — anyone on the internet can query it. For internal/split-horizon names use an Azure private DNS zone instead; there is no encryption knob for public DNS, the meaningful control is public vs private.
  • Publish a CAA record set (caa_records) to restrict which CAs may issue certificates for the domain — a cheap, high-value hardening step.
  • Use TXT records for SPF/DKIM/DMARC to lock down email spoofing.
  • The deploying principal needs the DNS Zone Contributor role (or equivalent) on the resource group to create zones and record sets.
