internal_fqdn attribute for network interfaces not exported

[pdeva]

Terraform Version

Terraform v0.11.3

• provider.azurerm v1.2.0

Affected Resource(s)

• azurerm_network_interface

Terraform Configuration Files

resource "azurerm_network_interface" "ni" {
  count = "${var.icount}"
  name                = "${var.instance_name}-${count.index}"
  location            = "${var.location}"
  resource_group_name = "${var.rg_name}"
  network_security_group_id = "${azurerm_network_security_group.nsg.id}"

  ip_configuration {
    name                          = "${var.instance_name}"
    subnet_id                     = "${var.subnet_id}"
    private_ip_address_allocation = "dynamic"
    public_ip_address_id = "${element(azurerm_public_ip.pubIp.*.id, count.index)}"
  }
}

output "fqdn" {
  value = ["${azurerm_network_interface.ni.*.internal_fqdn}"]
}

Expected Behavior

Should return the internal fqdn without errors

Actual Behavior

Error msg, like this:

 module.dev-kafka.output.fqdn: Resource 'azurerm_network_interface.ni' does not have attribute 'internal_fqdn' for variable 'azurerm_network_interface.ni.*.internal_fqdn'

looked at the terraform state file and internal_fqdn isnt stored there either

Steps to Reproduce

Create a network interface with >0 count and try to extract its internal_fqdn attribute in an output

hey @pdeva

Thanks for opening this issue

Taking a look into this, this value is only set if there's an actual value assigned for this key (I'll send a PR to default this to an empty string if nothing's specified). As such I can confirm that when specifying internal_fqdn this field is passed to Azure and returned in the state - would you be able to take a look and see if that resolves your issue here? Here's the configuration I'm referencing used:

resource "azurerm_resource_group" "test" {
  name     = "tharvey-devrg"
  location = "West Europe"
}

resource "azurerm_virtual_network" "test" {
  name                = "acctestvn-tom"
  address_space       = ["10.0.0.0/16"]
  location            = "${azurerm_resource_group.test.location}"
  resource_group_name = "${azurerm_resource_group.test.name}"
}

resource "azurerm_subnet" "test" {
  name                 = "testsubnet"
  resource_group_name  = "${azurerm_resource_group.test.name}"
  virtual_network_name = "${azurerm_virtual_network.test.name}"
  address_prefix       = "10.0.3.0/24"
}

resource "azurerm_network_interface" "test" {
  name                = "acctestni-tom"
  location            = "${azurerm_resource_group.test.location}"
  resource_group_name = "${azurerm_resource_group.test.name}"

  ip_configuration {
    name                          = "testconfiguration1"
    subnet_id                     = "${azurerm_subnet.test.id}"
    private_ip_address_allocation = "dynamic"
  }

  internal_fqdn = "hi"
}

Given this is a question about the configuration rather than a bug in Terraform - I'm going to close this issue for the moment.

Thanks!

@tombuildsstuff I don't understand why you have to set this when azure knows it under the hood. Is this an issue with azure not making it queryable?
