How to Deploy Active Directory (AD) Domain Controller (DC) Virtual Machine (VM) in Azure with Terraform

Blog Post --> https://gmusumeci.medium.com/how-to-deploy-active-directory-ad-domain-controller-dc-virtual-machine-vm-in-azure-with-d816130a96bd

This code:

• Define the Azure Provider
• Create a Resource Group
• Create a VNET
• Create a Subnet
• Create NSG (Network Security Group) for Client Machines to AD Domain Controllers.
• Create NSG (Network Security Group) for Communications between Domain Controllers.
• Create a NIC (Network Card) in this Subnet
• Create the Virtual Machine to Create a New AD Forest and Domain
• Create the Virtual Machine to Join an Existing Domain

How To deploy the code:

1. Clone the repo
2. Move the files "vm-dc2-main.tf" and "vm-dc2-output.tf" outside the folder
3. Execute "terraform init"
4. Execute "terraform apply"
5. When execution is complete and the DC1 is running, copy the files "vm-dc2-main.tf ", and "vm-dc2-output.tf" back to the folder
6. Execute "terraform apply"

Important Note

This code uses assign a public to each domain controller.
This is NOT recommended for production environments.
If you planning to use in production environments, make the following changes:

• Remove references to resource "azurerm_public_ip" in both VM1 and VM2 files
• Remove the line public_ip_address_id = azurerm_public_ip.dcX-eip.id in resource "azurerm_network_interface" for both VM1 and VM2 files. Replace X for 1 or 2.
