In this case, you need to configure the Terraform Azure provider. thanks , using this “${var.variableName}” works fine, Your email address will not be published. In either case, I highly recommend looking at leveraging Azure Key Vault or an alternative solution that can ensure proper security in handling those secrets. { Create Azure VMs with Terraform! Using VM Extensions with Terraform to Domain Join Virtual Machines VM Extensions are a fantastic way to yield post deployment configurations via template as code in Azure. The last block of code I have specified at the very end is a depends_on statement. One of Azure’s most common VM Extensions is the JoinADDomainExtension, which will join your Azure VM to an Active Directory machine after the machine has successfully been provisioned. In this tutorial, you’re not creating a module but you’ll follow the same practice. Once you have Terraform downloaded, copy it to a folder in your path and run terraform. However setting up a Windows 10 VM is much harder than you would imagine considering Azure is a Microsoft cloud service! Create the AzureRM provider in terraform. To start, you need to download and install Terraform: https://www.terraform.io/downloads.html. I know, hard to believe, right? Next, remove the Azure VM you just created and all other resources in the configuration file using terraform destroy. That’s it! This example provisions a basic Windows Virtual Machine on an internal network. Typically, VM extensions can be configured via the following block of ARM Template code (a fully working example building the virtual and running the extension can be found here). If you see this, you’re ready to proceed. Intro Prerequisites Deploying Multiple VMs with Multiple Data Disks Problems with count A Better Solution - for_each Results Conclusion Intro I recently came across an old module that I had developed on v0.11.7 which deploys Linux (Ubuntu) virtual machines on Azure, unfortunately not usable now as it requires a whole lot of refactoring. Learning the syntax of HCL is the hardest part of Terraform but honestly, HCL is an intuitive language. terraform import azurerm_virtual_machine.example /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/mygroup1/providers/microsoft.compute/virtualMachines/machine1 hosted_service_name - (Optional) The name of the hosted service the instance should be deployed under. I will try if this will run the script post deploy. This tutorial is using macOS so you can use HomeBrew by running brew install terraform. Assuming that you’ve got the Azure CLI installed and already authenticated to Azure, you ned to first create a service principal. Instead your Windows 10 VM will simply fail at the very end. The only thing I’ll leave you with is typically it is recommended to not leave clear-text passwords scattered through your templates. This section specifies the specific VM image that Terraform and Azure will deploy, however finding this information proves more difficult. The key pieces here are the SETTINGS and PROTECTED_SETTINGS blocks that allow you to pass the traditional JSON attributes as you would in the ARM template. acctvm is the name of the virtual machine. You build Terraform templates in a human-readable format that create and configure Azure resources in a consistent, reproducible manner. Terraform VM on the Azure Marketplace; Terraform VM on the Azure Marketplace. "commandToExecute": "powershell -ExecutionPolicy Unrestricted -File script.ps1", name = “RunCustomScript” Deploy your Azure VM. Luckily, terraform does a somewhat decent job documentation this on their public docs here, so if you have any additional questions on any of the attributes you can find them all here: https://www.terraform.io/docs/providers/azurerm/r/virtual_machine_extension.html. Once you have the subscription ID, then create a service principal using the Contributor role scoped to your subscription. Continuing along the lines of customizing a virtual machine post deployment, Azure has a handy dandy extension called CustomScriptExtension. Did you know that Azure Cloud Shell has Terraform pre-installed? Open up an Azure Cloud Shell session by going to shell.azure.com. Try replacing them var.variable name with “${var.variableName}”. To do that, run the terraform plan command. Additional examples of how to use the azurerm_windows_virtual_machine resource can be found in the ./examples/virtual-machine/windows` directory within the Github Repository. Permalink. "envName": var.OCTOPUS-TENANT, Changing this forces a new resource to be created. Since this tutorial is working within a PowerShell console, you can set these environment variables using $env:. Azure subscription. If not provided; it will default to the value of name.Changes to this parameter forces the creation of a new resource. Since you’re assigning the output shown below to the $sp variable above, you will have the appId and password stored in the variable for later use. At this point you should be able to leverage both extensions to join a machine to the domain and then customize virtually any aspect of the machine thereafter. TLDR: There are two sections of this article; feel free to scroll down to the titles for the applicable section. @Jack, it worked. There are 4 options and the easiest is to authenticate using Azure CLI. Terraform is a popular industry tool now with great community support and plenty of people to help! Next, create the main.tf configuration file. testvm is the resource instance name. virtual_machine_name = count.index == 0 ? In your PowerShell console, create a folder called TerraformTesting wherever you’d like then change to that directory. It must know this ahead of time because it downloads these providers in the same folder you’re working in. This simpy ensures that this resource is not created until the Virtual Machine itself has successfully been provisioned and can be very beneficial if you have other scripts that may need to run prior to domain join. In this case, you need to configure the Terraform Azure provider. If so, how many clicks did it take to do that? “vm-app-bastion-${var.Prefix}” : “vm-app-${count.index}-${var.Prefix}” It provides versioning for configurations, which makes it easy to deploy and maintain your existing Windows Virtual Desktop deployments on Microsoft Azure. If you’d like to learn more about the syntax (HCL), Michael Levan and I have a great chapter on Terraform in our No BS Azure and DevOps eBook. PROTECTED_SETTINGS text at the bottom, Terraform has built the resources successfully! type = “CustomScriptExtension” To login just run the below command. SETTINGS You can also go directly to the Terraform download page or, if you’re on Windows, you can use Chocolatey too. AgentName (azure_devops_agentname) - The name of the agent.

Terraform by Hashicorp is a utility that creates simple to complex infrastructure on-prem or in the cloud. terraform module terraform0-12 azure virtual-machine You can not select more than 25 topics Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long. The value is what is executed in command prompt, so if that string works fine in cmd.exe it should work fine specified in the commandToExecute field. In this article, you’re going to learn how to get started with Terraform by creating an Azure VM. "fileUris": ["https://azure.blob.core.windows.net/provisioning-scripts/iscript.ps1"%5D The jobs are spawned by a single Windows client. DeploymentGroup (azure_devops_deploymentgroup) - The deployment group agent you created above in “Set-Up”. 06/14/2020; 8 minutes to read; T; d; In this article. The entire code block provisions a Windows and a Linux VM, but feel free to delete one or the other and corresponding outputs. 2. You need to automate the process. Once you type “yes”, it will then reach out to Azure and begin building the VM and all associated resources. Cover image by Taylor Vick.
