This module was designed and implemented for AzureRM Provider v2.x, It's impossible to refactor this module from azurerm_virtual_machine
to the modern version azurerm_linux_virtual_machine
and azurerm_windows_virtual_machine
. For those who're maintaining infrastructure on brownfield, you're welcome to continue using this module; for those who're about to provision new infrastructure on greenfield, you're welcome to try our new alternative: terraform-azurerm-virtual-machine.
As #218 described, the plan
block introduced by #209 was incorrect so we must adjust the assignments' order, which is a breaking change. The change we've made to vm's plan
block is:
dynamic "plan" {
for_each = var.is_marketplace_image ? ["plan"] : []
content {
- name = var.vm_os_offer
- product = var.vm_os_sku
+ name = var.vm_os_sku
+ product = var.vm_os_offer
publisher = var.vm_os_publisher
}
}
Now vm_os_sku
would be used as plan.name
and vm_os_offer
would be used as plan.product
.
v5.0.0 is a major version upgrade. Extreme caution must be taken during the upgrade to avoid resource replacement and downtime by accident.
We've added a CI pipeline for this module to speed up our code review and to enforce a high code quality standard, if you want to contribute by submitting a pull request, please read Pre-Commit & Pr-Check & Test section, or your pull request might be rejected by CI pipeline.
A pull request will be reviewed when it has passed Pre Pull Request Check in the pipeline, and will be merged when it has passed the acceptance tests. Once the ci Pipeline failed, please read the pipeline's output, thanks for your cooperation.
v4.0.0 is a major version upgrade. Extreme caution must be taken during the upgrade to avoid resource replacement and downtime by accident.
Running the terraform plan
first to inspect the plan is strongly advised.
This Terraform module deploys Virtual Machines in Azure with the following characteristics:
- Ability to specify a simple string to get the latest marketplace image using
var.vm_os_simple
- All VMs use managed disks
- Network Security Group (NSG) created with a single remote access rule which opens
var.remote_port
port or auto calculated port number if usingvar.vm_os_simple
to all nics - VM nics attached to a single virtual network subnet of your choice (new or existing) via
var.vnet_subnet_id
. - Control the number of Public IP addresses assigned to VMs via
var.nb_public_ip
. Create and attach one Public IP per VM up to the number of VMs or create NO public IPs via settingvar.nb_public_ip
to0
. - Control SKU and Allocation Method of the public IPs via
var.allocation_method
andvar.public_ip_sku
.
Note: Terraform module registry is incorrect in the number of required parameters since it only deems required based on variables with non-existent values. The actual minimum required variables depends on the configuration and is specified below in the usage.

}

}
This contains the bare minimum options to be configured for the VM to be provisioned. The entire code block provisions a Windows and a Linux VM, but feel free to delete one or the other and corresponding outputs. The outputs are also not necessary to provision, but included to make it convenient to know the address to connect to the VMs after provisioning completes.
Provisions an Ubuntu Server 16.04-LTS VM and a Windows 2016 Datacenter Server VM using vm_os_simple
to a new VNet and opens up ports 22 for SSH and 3389 for RDP access via the attached public IP to each VM. All resources are provisioned into the default resource group called terraform-compute
. The Ubuntu Server will use the ssh key found in the default location ~/.ssh/id_rsa.pub
.

}
The following example illustrates some of the configuration options available to deploy a virtual machine. Feel free to remove the Linux or Windows modules and corresponding outputs.
More specifically this provisions:
1 - New vnet for all vms
2 - Ubuntu 18.04 Server VMs using vm_os_publisher
, vm_os_offer
and vm_os_sku
which is configured with:
- No public IP assigned, so access can only happen through another machine on the vnet.
- Opens up port 22 for SSH access with the default ~/.ssh/id_rsa.pub key
- Boot diagnostics is enabled.
- Additional tags are added to the resource group.
- OS disk is deleted upon deletion of the VM
- Add one 64GB premium managed data disk
2 - Windows Server 2012 R2 VMs using vm_os_publisher
, vm_os_offer
and vm_os_sku
which is configured with:
- Two Public IP addresses (one for each VM)
- Public IP Addresses allocation method is Static and SKU is Standard
- Opens up port 3389 for RDP access using the password as shown
3 - New features are supported in v3.0.0:
-
"nb_data_disk" Number of the data disks attached to each virtual machine
-
"enable_ssh_key" Enable ssh key authentication in Linux virtual Machine. When ssh keys are enabled you can either
- use the default "~/.ssh/id_rsa.pub"
- set one key by setting a path in ssh_key variable. e.g "joey_id_rsa.pub"
- set ssh_key and add zero or more files paths in extra_ssh_keys variable e.g. ["ross_id_rsa.pub", "rachel_id_rsa.pub"] (since v3.8.0)
- set ssh_key_values as a list of raw public ssh keys values or refer it to a data source with the public key value, e.g.
["ssh-rsa AAAAB3NzaC1yc..."]
4 - You can install custom certificates / secrets on the virtual machine from Key Vault by using the variable os_profile_secrets
.
The variable accepts a list of maps with the following keys:
- source_vault_id : The ID of the Key Vault Secret which contains the encrypted Certificate.
- certificate_url : The certificate URL in Key Vault
- certificate_store : The certificate store on the Virtual Machine where the certificate should be added to (Windows Only).
In the below example we use the data sources azurerm_key_vault
and azurerm_key_vault_certificate
to fetch the certificate information from Key Vault and add it to windowsservers
via os_profile_secrets
parameter.

We assumed that you have setup service principal's credentials in your environment variables like below:
export ARM_SUBSCRIPTION_ID="<azure_subscription_id>"
export ARM_TENANT_ID="<azure_subscription_tenant_id>"
export ARM_CLIENT_ID="<service_principal_appid>"
export ARM_CLIENT_SECRET="<service_principal_password>"
On Windows Powershell:
$env:ARM_SUBSCRIPTION_ID="<azure_subscription_id>"
$env:ARM_TENANT_ID="<azure_subscription_tenant_id>"
$env:ARM_CLIENT_ID="<service_principal_appid>"
$env:ARM_CLIENT_SECRET="<service_principal_password>"
We provide a docker image to run the pre-commit checks and tests for you: mcr.microsoft.com/azterraform:latest
To run the pre-commit task, we can run the following command:
$ docker run --rm -v $(pwd):/src -w /src mcr.microsoft.com/azterraform:latest make pre-commit
On Windows Powershell:
$ docker run --rm -v ${pwd}:/src -w /src mcr.microsoft.com/azterraform:latest make pre-commit
NOTE: If an error occurs in Powershell that indicates Argument or block definition required
for unit-fixture/locals.tf
and/or unit-fixture/variables.tf
, the issue could be that the symlink is not configured properly. This can be fixed as described in this link:
$ git config core.symlinks true
Then switch branches, or execute git reset:
$ git reset --hard HEAD
In pre-commit task, we will:
- Run
terraform fmt -recursive
command for your Terraform code. - Run
terrafmt fmt -f
command for markdown files and go code files to ensure that the Terraform code embedded in these files are well formatted. - Run
go mod tidy
andgo mod vendor
for test folder to ensure that all the dependencies have been synced. - Run
gofmt
for all go code files. - Run
gofumpt
for all go code files. - Run
terraform-docs
onREADME.md
file, then runmarkdown-table-formatter
to format markdown tables inREADME.md
.
Then we can run the pr-check task to check whether our code meets our pipeline's requirement(We strongly recommend you run the following command before you commit):
$ docker run --rm -v $(pwd):/src -w /src mcr.microsoft.com/azterraform:latest make pr-check
On Windows Powershell:
$ docker run --rm -v ${pwd}:/src -w /src mcr.microsoft.com/azterraform:latest make pr-check
To run the e2e-test, we can run the following command:
docker run --rm -v $(pwd):/src -w /src -e ARM_SUBSCRIPTION_ID -e ARM_TENANT_ID -e ARM_CLIENT_ID -e ARM_CLIENT_SECRET mcr.microsoft.com/azterraform:latest make e2e-test
On Windows Powershell:
docker run --rm -v ${pwd}:/src -w /src -e ARM_SUBSCRIPTION_ID -e ARM_TENANT_ID -e ARM_CLIENT_ID -e ARM_CLIENT_SECRET mcr.microsoft.com/azterraform:latest make e2e-test
