Terraform (and AzureRM Provider) Version

Terraform v0.11.10

• provider.azurerm v1.19.0

Affected Resource(s)

• data.azurerm_public_ip

Terraform Configuration Files

data "azurerm_public_ip" "pubip" {
  name                = "${var.name}"
  resource_group_name = "${var.resource_group["name"]}"
}
output "instance" {
  value = {
    id          = "${data.azurerm_public_ip.pubip.id}"
    name        = "${data.azurerm_public_ip.pubip.name}"
    fqdn        = "${data.azurerm_public_ip.pubip.fqdn}"
    domain_name = "${data.azurerm_public_ip.pubip.domain_name_label}"
    ip_address  = "${data.azurerm_public_ip.pubip.ip_address}"
  }
}

Expected Behavior

Terraform apply will dump out the information on the public ip resource found in Azure.

Actual Behavior

If the public ip address is of type "dynamic" and is not associated with a network device the query will fail. Terraform plan will complain that the attributes fqdn, domain_name and ip_address are not known.

The Terraform state only has:

module.test-find-publicip2.data.azurerm_public_ip.pubip:
  id = /subscriptions/XXXXX/resourceGroups/AppServicesDev/providers/Microsoft.Network/publicIPAddresses/dev-ip2
  idle_timeout_in_minutes = 4
  ip_version = IPv4
  name = dev-ip2
  resource_group_name = AppServicesDev
  tags.% = 0

If on the other hand the "dynamic" ip address is assigned to a network device accordingly, it will properly display all the information.

The Terraform state shows:

module.test-find-publicip.data.azurerm_public_ip.pubip:
  id = /subscriptions/XXXX/resourceGroups/AppServicesDev/providers/Microsoft.Network/publicIPAddresses/dev-ip
  domain_name_label = <xyz>
  fqdn = <xyz>.westeurope.cloudapp.azure.com
  idle_timeout_in_minutes = 4
  ip_address = <an IPv4 address>
  ip_version = IPv4
  name = dev-ip
  resource_group_name = AppServicesDev
  tags.% = 0

There is no way currently to check for the existence of the attributes in HCL to manage the output. There is no attribute to signal the status of a dynamically assigned public ip that can eventually used in a condition statement.
