Using Terraform, you create configuration files using HCL syntax.

Using Terraform with Azure VM Extensions

The HCL syntax allows you to specify the cloud provider - such as Azure - and the elements that make up your cloud infrastructure. After you create your configuration files, you create an execution plan that allows you to preview your infrastructure changes before they're deployed. Once you verify the changes, you apply the execution plan to deploy the infrastructure.

This article describes getting started with Terraform on Azure from the Azure Cloud Shell environment. If you aren't already logged in, the Azure portal displays a list of available Microsoft accounts. Select a Microsoft account associated with one or more active Azure subscriptions and enter your credentials to continue.

If you haven't previously used Cloud Shell, configure the environment and storage settings. This article uses the Bash environment. Cloud Shell is automatically authenticated under the Microsoft account with which you logged into the Azure portal. Also, once logged into your Microsoft account, you are automatically logged into the default Azure subscription for that account. If the current Microsoft account is correct, and you want to switch subscriptions, see the section, Specify the current Azure subscription.

If you have multiple Microsoft accounts with Azure subscriptions, you can log into one of those accounts using any of the following options:. Calling az login without any parameters displays a URL and a code. Browse to the URL, enter the code, and follow the instructions to log into Azure using your Microsoft account.

Once you're logged in, return to the portal. Create an Azure service principal : To log into an Azure subscription using a service principal, you first need access to a service principal.

If you already have a service principal, you can skip this part of the section.

In that scenario, you can log in using your user credentials and then create a service principal. Once the service principal is created, you can use its information for future login attempts.

There are many options when creating a service principal with the Azure CLI. For this article, we'll create use az ad sp create-for-rbac to create a service principal with a Contributor role. The Contributor role the default has full permissions to read and write to an Azure account.

This article describes the benefits of using Terraform to manage Azure infrastructure. Automate infrastructure management. Automating infrastructure has several benefits: Lowers the potential for human errors while deploying and managing infrastructure.

Deploys the same template multiple times to create identical development, test, and production environments. Reduces the cost of development and test environments by creating them on-demand. Understand infrastructure changes before being applied As a resource topology becomes complex, understanding the meaning and impact of infrastructure changes can be difficult. Previewing infrastructure changes in a safe manner has several benefits: Team members can collaborate more effectively by quickly understanding proposed changes and their impact.

Unintended changes can be caught early in the development process Deploy infrastructure to multiple clouds Terraform is adept at deploying an infrastructure across multiple cloud providers. Next steps Now that you have an overview of Terraform and its benefits, here are suggested next steps: Get started by installing Terraform and configuring it to use Azure. Yes No. Any additional feedback?Most of us have done it—deployed temporary VMs to Azure.

Something that many of us also have done is to forget to remove resources attached to those VMs when deleting them. Terraform can be installed in a a few different ways. In Windows, the easiest way is to use choco:. More information about installing Terraform is available in the Terraform documentation. Assuming that everything has gone well with the installation, you can confirm that it works by running the command terraform version.

To authenticate and set the subscription in the Azure CLI, you need to login. Open a terminal and type:. If you have several subscriptions available, copy the subscription id of the correct one and enter:. You have now set the Azure CLI to use your subscription. This is the subscription that terraform will use later as well. It is now time to create the terraform template that we will use to deploy our VM.

The Terraform template is a simple text file with the file ending. It has a JSON-like syntax, and can be read and generated easily. The template consists of mainly two parts: the providers that handle the communication to the service in which you wish to deploy toand the resources that the provider creates.

We start out by creating a file called vm. Terraform will need an empty dir so that it can write the state of the configuration later on. This will tell Terraform that you want to use the AzureRM provider for creating azure resourcesand that it should be of version 2. It is important to specify the version number because the functionality between different versions may vary heavily. This is seen by Terraform as a resource as well:. It also adds a tag with the project name on it.

To run a VM successfully, we also need a network. This creates a virtual network. It also uses a variable in the name parameter. If you look carefully, you will see that it refers to the resource group that we defined above:.

That means that the virtual network will be given the name test-vm-network. We do the same for the location, resource group name, and tags as well. Next up, it is time to define the subnet that we will place the VM in, using the same methods using variables as before:. The code above will provision an Azure VM running Windows Serverusing the resources that we defined previously. The rest of the parameters are pretty self-explanatory, and you can find a lot more of themin the Terraform AzureRM documentation.

Now, all that is left is to save the. Now that we have the template in order, open up a terminal, and go to the directory that you saved the.
