We are migrating from unmanaged to managed disks in Azure. Currently our backend.tf definition is as follows
terraform {
backend "azure" {
storage_account_name = "foo"
container_name = "foo-container"
key = "foo.tfstate"
}
}
With managed disks you don't have reference to storage account as it is managed by Azure. What does this mean for backend.tf. Do we just remove storage account and container? Do we need to add some flag to identify backend storage as managed? Google search is not producing required answers, hence reaching out here.
Thanks
With managed disks you don't have reference to storage account as it

It means you could not use backend "azure", Azure managed disk does not support this.
Please refer to this official document.Stores the state as a given key in a given blob container on Microsoft Azure Storage.
Creating managed disk with terraform you could check this link.
resource "azurerm_managed_disk" "test" {
name = "acctestmd"
location = "West US 2"
resource_group_name = "${azurerm_resource_group.test.name}"
storage_account_type = "Standard_LRS"
create_option = "Empty"
disk_size_gb = "1"
tags {
environment = "staging"
}

I want to deploy with Terraform some Virtual machines inside Azure Stack Edge. Is it possible?
From the Azure documentation Here, I suspect that I can use the same Terraform code to create virtual machines in a Resource Group because it seems that they use the same Azure API, but I'm not sure.
If so, how could I adapt my code to use a Azure Stack Edge instead of Azure Resource group?
#Creating the VM
resource "azurerm_windows_virtual_machine" "jumphost" {
name = var.name
resource_group_name = data.azurerm_resource_group.jumphost.name
location = data.azurerm_resource_group.jumphost.location
size = "Standard_B2ms"
admin_username = "adminuser"
admin_password = data.azurerm_key_vault_secret.jumphost.value
network_interface_ids = [
azurerm_network_interface.jumphost.id,
]
os_disk {
caching = "ReadWrite"
storage_account_type = "Standard_LRS"
disk_size_gb = 127
}
source_image_reference {
publisher = "MicrosoftWindowsServer"
offer = "WindowsServer"
sku = "2022-Datacenter"
version = "latest"
}
}
This is an example how I deploy a VM.
Many Thanks
Both The Azure Stack Provider and Azure Provider are used to manage resources via the Azure Resource Manager API's..You can use the same terraform code to deploy resources in Azure Stack or AzureRM. Only you need to change the providers.
Below is screen shot from terraform registry.
Terraform, created by Microsoft partner HashiCorp, is using the same ARM REST APIs as a foundation.

I have a .vhd saved in my Azure storage account. I have the container set to allow anonymous read and from an unauthenticated browser I can indeed download the VHD.
My code:
resource "azurerm_managed_disk" "MyDisk" {
name = "MyDisk"
location = var.location
resource_group_name = azurerm_resource_group.rg.name
storage_account_type = "Standard_LRS"
create_option = "Copy"
source_resource_id = "/subscriptions/.../resourceGroups/ProvisioningScripts/providers/Microsoft.Storage/storageAccounts/myvhds/blobServices/default"
source_uri = "https://....blob.core.windows.net/images/mydisk.vhd"
disk_size_gb = "32"
tags = {
environment = "staging"
}
}
I am getting the following error when I try to apply:
Error: Error creating/updating Managed Disk "MyDisk" (Resource Group "rg"): compute.DisksClient#CreateOrUpdate: Failure sending request: StatusCode=403 -- Original Error: Code="LinkedAuthorizationFailed" Message="The client has permission to perform action 'Microsoft.Compute/disks/beginGetAccess/action' on scope '/subscriptions/.../resourceGroups/rg/providers/Microsoft.Compute/disks/MyDisk', however the current tenant '4019...' is not authorized to access linked subscription '626c...'."
Thank you much for your help.
It's impossible to create a managed disk from a VHD file in a different Tenant directly. You need to copy the VHD file to a storage account in the same tenant and same subscription, and then you can create a new managed disk from the VHD file in that subscription. Of course, your account needs to have enough permissions to copy and create.
What is Terraform equivalent to
az vm encryption enable --name --resource-group --volume-type OS --aad-client-id --aad-client-secret --disk-encryption-keyvault https:///secrets//
Based on this Repository
We configure the Azure Key Vault service for Server-side encryption
(SSE) for the Azure Managed Disk in this config. The procedured can be
procured using the Terraform provider azurerm_disk_encryption_set.
resource "azurerm_disk_encryption_set" "example" {
name = "des"
resource_group_name = azurerm_resource_group.example.name
location = azurerm_resource_group.example.location
key_vault_key_id = azurerm_key_vault_key.example.id
identity {
type = "SystemAssigned"
}
}
How to manage terraform state file in azure for preventing deletion and replacement,
just like arm templates.
I am deploying VMs with terraform and terraform plan and apply is replacing
my vms each time.
You could store Terraform state in Azure Storage from this tutorial, Azure Storage blobs are automatically locked before any operation that writes state.
If so, you will configure the state back end. The Terraform state back end is configured when you run the terraform init command. The following data is needed to configure the state back end:
storage_account_name: The name of the Azure Storage account.
container_name: The name of the blob container.
key: The name of the state store file to be created.
access_key: The storage access key.
Here is an example.
terraform {
backend "azurerm" {
resource_group_name = "tstate"
storage_account_name = "tstate09762"
container_name = "tstate"
key = "terraform.tfstate"
}
}
resource "azurerm_resource_group" "state-demo-secure" {
name = "state-demo"
location = "eastus"
}
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:
Create a Windows VM from an Image (have resource Id)
I already have Resource group, Virtual network, Subnet created. I just need to pass those values and create them.
We have already defined the Subnet address prefix, Vnet address space from the portal itself. So do I have to give again in the script or can I skip it.
The business requirement is that no VMs should have public IP and DNS name, So if I remove "# Create public IPs" section, will that not create public IP?
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.
