Azure :: Landing Zone :: Hub-Spoke :: Terraform Modules

This repo contains Terraform modules for building a multi-region Hub-Spoke infrastructure in Azure that supports the Landing Zone architectural pattern.

Usage

Modules could be used in your Terraform code by referencing this repo in the module block the following way:

module "linux_scale_set" {
  source = "github.com/undp/tf-modules//azure_landing_zone/vmss_for_each_rg?ref=v0.1.4rc1"

  region_rg_map = {
    eastus        = "rg1"
    canadacentral = "rg2"
  }

  conf_module = {
    enable_const_capacity = true
    enable_lb_ext         = true
    enable_lb_ext_nat_ssh = true
  }

  conf_common = {
    vm_size      = "Standard_DS1_v2"
    vm_instances = 2

    image_publisher = "Canonical"
    image_offer     = "UbuntuServer"
    image_sku       = "18.04-LTS"
    image_version   = "latest"

    os_disk_ephemeral = true
  }

  conf_map = {
    eastus  = {
      name = "alice"
      admin_username = "admin_alice"
      public_key = file("alice_ssh_key.pub")
    }
    canadacentral = {
      name = "bob"
      admin_username = "admin_bob"
      public_key = file("bob_ssh_key.pub")
    }
  }

  namespace = "deep"

  tags = {
    BU    = "Enterprise"
    Owner = "Security"
  }
}

Requirements

All modules have common.tf symlink to the single file defining the following requirements for the version of Terraform and Azure provider.

• Terraform >= 0.12
• Azure provider = 2.0

It is also expected that Terraform state is stored using azurerm backend. It is advised to use a tool like Terragrunt to manage state storage compartmentalization.

Versioning

We use Semantic Versioning Specification as a version numbering convention.
