In Azure, I'm trying to create a Windows VM using Terraform. I have done this through Powershell previously using Template.json file. Now I have to do with terraform, which I'm completely new to. So I have searched for some Sample scripts which creates VM in Azure and found this .
In this link, there is a sample Terraform script to spin a Linux VM. But I need to spin a windows VM from an Image. Where should I give the Image details. My complete requirement is:
The script for creating a Linux machine is here , which I'm taking it as reference.
Below is an example of how to use data to use already existing resources in terraform, also there is a code block to create a windows VM. You will need to get the existing VNET and create a NIC
Use the data directive to get the VNET azurerm_virtual_network
, you can see the syntax below for the resource group. You will need to add the resource group and possibly location into this block.
Create a azurerm_network_interface
resource using the VNET ID
Add the network interface ID to the VM (network_interface_ids = [])
Example TF Code to Create and load balance VMs
variable "subscription_id" {}
variable "client_id" {}
variable "client_secret" {}
variable "tenant_id" {}
provider "azurerm" {
tenant_id = "${var.tenant_id}"
subscription_id = "${var.subscription_id}"
client_id = "${var.client_id}"
client_secret = "${var.client_secret}"
}
data "azurerm_resource_group" "resource_group" {
name = "learning-tf-web-rg"
}
resource "azurerm_virtual_machine" "web_server" {
name = "server"
location = "westus2"
resource_group_name = "${data.azurerm_resource_group.resource_group.name}"
network_interface_ids = []
vm_size = "Standard_B2s"
storage_image_reference {
publisher = "MicrosoftWindowsServer"
offer = "WindowsServer"
sku = "2016-Datacenter-Server-Core-smalldisk"
version = "latest"
}
storage_os_disk {
name = "server-os"
caching = "ReadWrite"
create_option = "FromImage"
managed_disk_type = "Standard_LRS"
}
os_profile {
computer_name = "server"
admin_username = "server"
admin_password = "Passw0rd1234"
}
os_profile_windows_config {
}
}
From Terraform's perspective, a Windows VM is really quite similar to a Linux VM. The #1 difference in my opinion is that the Windows VM requires a os_profile_windows_config
attribute, while the Linux VM needs os_profile_linux_config
.
The TF code you found on the Microsoft site is a fine start. Additionally, you may look in the Terraform Registry . For example, here's a module for a Linux VM .
I strongly recommend reading through all of the options in the VM resource . I know it's a lot, but you should understand what choices you have.
Lastly, there's no substitute for writing some code and testing it. If you do something wrong, either Terraform and/or the Azure API will tell you, and if it's unclear, a web search will pop up an answer or a pointer in the right direction.
