I have created a module network resources . Below is the code used:
locals.tf
locals {
subnets_flatlist = flatten([for key, val in var.vnets : [
for subnet in val.subnets : {
vnet_name = key
subnet_name = subnet.subnet_name
subnet_address = subnet.subnet_address
}
]
])
subnets = { for subnet in local.subnets_flatlist : subnet.subnet_name => subnet }
}
main.tf
data “azurerm_resource_group” “network” {
name = var.resource_group_name
}
resource “azurerm_virtual_network” “vnets” {
for_each = var.vnets
name = each.key
resource_group_name = data.azurerm_resource_group.network.name
location = data.azurerm_resource_group.network.location
address_space = [each.value.address_space]
}
resource “azurerm_subnet” “subnets” {
for_each = local.subnets
name = each.value.subnet_name
resource_group_name = data.azurerm_resource_group.network.name
virtual_network_name = azurerm_virtual_network.vnets[each.value.vnet_name].name
address_prefixes = [each.value.subnet_address]
}
output.tf
output “vnet_names” {
description = “The name of the virtual networks”
value = {for k, v in azurerm_virtual_network.vnets: k => v.name}
}
output “vnet_addresses” {
description = “The name of the virtual networks”
value = {for k, v in azurerm_virtual_network.vnets: k => v.address_space}
}
output “subnet_names” {
description = “The name of the subnets”
value = {for k, v in azurerm_subnet.subnets: k => v.name}
}
output “subnet_addresses” {
description = “The name of the subnet addresses”
value = {for k, v in azurerm_subnet.subnets: k => v.address_prefixes}
}
output “subnet_ids” {
description = “The name of the subnet ids”
value = {for k, v in azurerm_subnet.subnets: k => v.id}
}
variables.tf
variable “resource_group_name” {
description = “Name of the resource group to be imported.”
type = string
}
variable “location” {
description = “The location of the vnet to create. Defaults to the location of the resource group.”
type = string
default = null
}
variable “vnets” {
type = map(object({
address_space = string
subnets = list(object({
subnet_name = string
subnet_address = string
}))
}))
default = {
"bupavnet1" = {
address_space = "192.168.0.0/16",
subnets = []
},
"bupavnet2" = {
address_space = "10.0.0.0/16",
subnets = [
{
subnet_name = "subnet1_bupavnet1"
subnet_address = "10.0.2.0/24"
},
{
subnet_name = "subnet2_bupavnet1"
subnet_address = "10.0.0.0/24"
}
]
},
"bupavnet3" = {
address_space = "10.80.0.0/16"
subnets = [
{
subnet_name = "subnet1_bupavnet3"
subnet_address = "10.80.2.0/24"
},
{
subnet_name = "subnet2_bupavnet3"
subnet_address = "10.80.1.0/24"
},
{
subnet_name = "subnet3_bupavnet3"
subnet_address = "10.80.0.0/24"
},
]
}
}
}
I have a nsg module where i need to pass the subnet id which will be created from the above module. The output defined here is creating a group of subnet ids. Kindly help me in using one of those subnet ids in my nsg module.
