Terraform for Dynamic Azure VM

Dynamic VM creation for Windows or Linux's

This Terraform code will create VM for windows or for linux's with its necessary resource

• Virtual Network
• Public IP
• Network Interface - NIC
• Subnet - Inside Virtual Network

Terraform Azurerm

• Provider version is 2.16
• This terraform code is capable for azurerm provider version 2.0.0+

 provider "azurerm" {
  version = "=2.16"
  features {}
 }

Set version as per requirement.

How to create Windows VM or Linux's VM

For Windows:

Windows Virtual Machine (VM) creation is very simple and easy

• required to set one variable os_type in terraform.tfvars

    os_type = "Windows"

This will ensure it will create only Windows Virtual Machine

For Linux's:

Linux's Virtual Machine (VM) creation is very simple and easy

• required to set one variable os_type in terraform.tfvars

    os_type = "Linux"

This will ensure it will create only Linux's Virtual Machine

More Suitable Configuration for Windows or Linuxs image

List of image obtain by running azure-cli command given in following link click here for more information

Example: To obtain list of Windows image available in West Europe

az vm image list -p MicrosoftWindowsServer -l 'West Europe' --all

In Terraform code main.tf provide input values for following block of code to the respective variables

For Windows Image: only when os_type = "Windows"

#Windows image
  dynamic "storage_image_reference" {
    for_each = local.windows
    content {
      publisher = "MicrosoftWindowsServer"
      offer     = "WindowsServer"
      sku       = "2016-Datacenter"
      version   = "latest"
    }
  }

For Linux's Image: only when os_type = "Linux"

#linux image
  dynamic "storage_image_reference" {
    for_each = local.linux
    content {
      publisher = "Canonical"
      offer     = "UbuntuServer"
      sku       = "16.04-LTS"
      version   = "latest"
    }
  }
