Terraform azure virtual network module

Question

I have written the below code for creating a virtual network in terraform azure: I have files in the root folder for main.tf,variables.tf and terraform.tfvars. I have got two modules for resource group and virtual network.

In the root folder I have the below code: main.tf

 #Resource Group Creation module "resource_group" { source = "./modules/resource_group" rgname_var = var.resource_group loc_var = var.location } #Virtual Network Creation module "vnet" { source = "./modules/vnet" loc = module.resource_group.loc_o rgname = module.resource_group.rgname_o

terraform.tfvars:

 vnet_name = "VirtualNetwork" vnet_address_space = [<3 subnet ips>]

variables.tf:

 variable "vnet_name" { default = "" } variable "vnet_address_space" { default = "" }

In the vnet module, I have the below code:

 resource "azurerm_virtual_network" "vnet" { name = var.vnet_name count = length(var.vnet_address_space) address_space = var.vnet_address_space[count.index] location = var.loc resource_group_name = var.rgname } #Subnet Creation resource "azurerm_subnet" "subnet-1" { name= var.subnet_name1 resource_group_name = var.rgname virtual_network_name = azurerm_virtual_network.vnet.name address_prefix = azurerm_virtual_network.vnet[0].vnet_address_sace } #Subnet Creation resource "azurerm_subnet" "subnet-2" { name= var.subnet_name2 resource_group_name = var.rgname virtual_network_name = azurerm_virtual_network.vnet.name address_prefix = azurerm_virtual_network.vnet[1].vnet_address_sace } #Subnet Creation resource "azurerm_subnet" "subnet-3" { name= var.subnet_name3 resource_group_name = var.rgname virtual_network_name = azurerm_virtual_network.vnet.name address_prefix = azurerm_virtual_network.vnet[2].vnet_address_sace }

I am getting the below error for three subnets:

19: address_prefix = azurerm_virtual_network.vnet[0].vnet_address_sace This object has no argument, nested block, or exported attribute named "vnet_address_sace".

I have tried giving one ip for virtual network address space at the first place,because it was working for single subnets. then the system was expecting list instead of string. Any idea how to set the values for virtual network?

According to the azurerm_virtual_network cocs, the correct argument is address_space , not vnet_address_sace . So in the code, it should be:

azurerm_virtual_network.vnet[0].address_space

not

azurerm_virtual_network.vnet[0].vnet_address_sace
