terraform-azure-res-ipam

This Terraform module is designed to deploy IPAM (IP Address Management) pools into an existing Azure Virtual Network Manager. It simplifies the process of managing IP address spaces across multiple virtual networks in Azure.

Requirements

• Terraform >= 1.0
• Azure Virtual Network Manager already configured.

Examples

Example input

subscription_id                             = ""
virtual_network_manager_name                = "avnm"
virtual_network_manager_resource_group_name = "avnm"

ipam_pools = {
  name                  = "root"
  display_name          = "root"
  main_address_prefixes = ["10.0.0.0/16", "10.1.0.0/16"]
  child_pools = {
    level21 = {
      name           = "level21"
      display_name     = "level21"
      address_prefixes = ["10.0.1.0/24", "10.0.2.0/24"]
    }
    level22 = {
      name           = "level22"
      display_name     = "level22"
      address_prefixes = ["10.1.1.0/24", "10.1.2.0/24"]
    }
  }
}

ipam_pools_level_3_and_4 = {
  name                  = "level31"
  display_name          = "level31"
  main_address_prefixes = ["10.1.1.0/24"]
  parent_pool_name = "level22"
  child_pools = {
    level41 = {
      name            = "level41"
      display_name     = "level41"
      address_prefixes = ["10.1.1.0/25"]
    }
  }
}

Example on how to create a new virtual network

resource "azurerm_virtual_network" "this" {
  name                = "example-vnet"
  location            = "westeurope"
  resource_group_name = "example-rg"
  ip_address_pool {
    id                     = module.ipam_pools.ipam_child_pools["child1"].id
    number_of_ip_addresses = 256
  }
