Description

Support Alias records in Azure DNS for public zones. This feature allows referencing other Azure resources from within their DNS zones such that the DNS records get updated automatically when there is a lifecycle event on the referenced Azure resources.

Sample ARM template block:

{
    "type": "Microsoft.Network/dnszones/A",
    "apiVersion": "2018-05-01",
    "name": "[concat(parameters('dnszones_bla.foo_name'), '/@')]",
    "dependsOn": [
         "[resourceId('Microsoft.Network/dnszones', parameters('dnszones_bla.foo_name'))]"
    ],
    "properties": {
         "TTL": 3600,
         "targetResource": {
             "id": "[concat(parameters('profiles_cdnprofileabc_externalid'), '/endpoints/blafoobar')]"
         }
     }
},

New or Affected Resource(s)

• azurerm_dns_a_record
• azurerm_dns_aaaa_record
• azurerm_dns_cname_record

Potential Terraform Configuration

resource "azurerm_dns_a_record" "test" {
  name                = "test"
  zone_name           = "${azurerm_dns_zone.test.name}"
  resource_group_name = "${azurerm_resource_group.test.name}"
  ttl                 = 300
  targetResource      = "${azurerm_cdn_endpoint.test.name}"
}

FYI, this will require an update of the SDK version

I'm also affected by this. My use case requires the '@' record creating to enable aliasing at the zone level. Something like this:

resource "azurerm_dns_a_record" "test" {
  name                = "@"
  zone_name           = "${azurerm_dns_zone.test.name}"
  resource_group_name = "${azurerm_resource_group.test.name}"
  ttl                 = 300
  target_resource_id  = "${azurerm_cdn_endpoint.test.id}"
}

I have started taking a look at this: matt-FFFFFF/terraform-provider-azurerm#2

Initial testing with A records has been successful.
