Unable to create and attach a public ip ro a VM by terraform

Question

I am getting the below error when I try to create a public ip

2019-05-27T03:07:44.5185437Z * azurerm_network_interface.tf-ni-erx-sqlcl1[1]: Resource 'azurerm_public_ip.tf-pip-erx-sqlcl1' not found for variable 'azurerm_public_ip.tf-pip-erx-sqlcl1.id'

My terraform code is as below:

resource "azurerm_public_ip" "tf-pip-erx-sqlcl1" {
  count                     = "${var.count_sqlcl1_vm}"
  name                      = "${var.sql_base_hostname}${format("%02d",count.index+1)}-pip01"
  location                  = "${data.azurerm_resource_group.tf-rg-erx-external.location}"
  resource_group_name       = "${data.azurerm_resource_group.tf-rg-erx-external.name}"
  allocation_method         = "Dynamic"
}
# Network inteface for sql
resource "azurerm_network_interface" "tf-ni-erx-sqlcl1" {
 count               = "${var.count_sqlcl1_vm}"
 name                = "${var.bussvc_base_hostname}${format("%02d",count.index+1)}-nic01"
 location            = "${data.azurerm_resource_group.tf-rg-erx-external.location}"
 resource_group_name = "${data.azurerm_resource_group.tf-rg-erx-external.name}"

ip_configuration {
    name                          = "${var.sql_base_hostname}${format("%02d",count.index+1)}-iip01"
    subnet_id                     = "${data.azurerm_subnet.tf-sn-erx-sql.id}"
    private_ip_address_allocation = "${var.env=="msdn"?"dynamic":"static"}"
    #private_ip_address            = "${var.env=="msdn"?"":"10.112.3.${count.index+10}"}"
    public_ip_address_id          = "${azurerm_public_ip.tf-pip-erx-sqlcl1.id}"
}
}
resource "azurerm_public_ip" "tf-pip-erx-sqlcl2" {
  count                     = "${var.count_sqlcl2_vm}"
  name                      = "${var.sql_base_hostname}${format("%02d",count.index+1)}-pip01"
  location                  = "${data.azurerm_resource_group.tf-rg-erx-external.location}"
  resource_group_name       = "${data.azurerm_resource_group.tf-rg-erx-external.name}"
  allocation_method         = "Dynamic"
}
resource "azurerm_network_interface" "tf-ni-erx-sqlcl2" {
 count               = "${var.count_sqlcl2_vm}"
 name                = "${var.sql_base_hostname}${format("%02d%s",count.index,var.count_sqlcl1_vm)}-nic01"
 location            = "${data.azurerm_resource_group.tf-rg-erx-external.location}"
 resource_group_name = "${data.azurerm_resource_group.tf-rg-erx-external.name}"

ip_configuration {
    name                          = "${var.sql_base_hostname}${format("%02d",count.index+1)}-iip01"
    subnet_id                     = "${data.azurerm_subnet.tf-sn-erx-sql.id}"
    private_ip_address_allocation = "${var.env=="msdn"?"dynamic":"static"}"
    #private_ip_address           = "10.112.3.${count.index+15}"
    public_ip_address_id          = "${azurerm_public_ip.tf-pip-erx-sqlcl2.id}"
}
}

I'm unable to understand what is the issue, I specifically added "depends_on" to network interface , ip configuration block like below

depends_on                    = "[azure_public_ip.tf-pip-erx-sqlcl2]"

The idea behind to do so is to ensure public ip is created before network interface resource is created but unfortunately that does not help either.

It reports error as below,

Error: azurerm_network_interface.tf-ni-erx-sqlcl2[1]: ip_configuration.0: invalid or unknown key: depends_on

Any assistance would be highly appreciated.

About the error, since your resource "azurerm_network_interface" has count, you could change the public_ip_address_id like this with element function:

public_ip_address_id          = "${element(azurerm_public_ip.tf-pip-erx-sqlcl1.*.id,count.index)}"

and

public_ip_address_id          = "${element(azurerm_public_ip.tf-pip-erx-sqlcl2.*.id,count.index)}"
