azurerm	Provider: Azure Resource Manager	docs-azurerm-index	The Azure Resource Manager provider is used to interact with the many resources supported by Azure, via the ARM API. This supercedes the Azure provider, which interacts with Azure using the Service Management API. The provider needs to be configured with a credentials file, or credentials needed to generate OAuth tokens for the ARM API.

Microsoft Azure Provider

The Microsoft Azure Provider provider is used to interact with the many resources supported by Azure, via the ARM API. This supercedes the legacy Azure provider, which interacts with Azure using the Service Management API. The provider needs to be configured with the credentials needed to generate OAuth tokens for the ARM API.

Use the navigation to the left to read about the available resources.

Example Usage

# Configure the Microsoft Azure Provider
provider "azurerm" {
  subscription_id = "..."
  client_id       = "..."
  client_secret   = "..."
  tenant_id       = "..."
}

# Create a resource group
resource "azurerm_resource_group" "production" {
    name     = "production"
    location = "West US"
}

# Create a virtual network in the web_servers resource group
resource "azurerm_virtual_network" "network" {
  name                = "productionNetwork"
  address_space       = ["10.0.0.0/16"]
  location            = "West US"
  resource_group_name = "${azurerm_resource_group.production.name}"

  subnet {
    name           = "subnet1"
    address_prefix = "10.0.1.0/24"
  }

  subnet {
    name           = "subnet2"
    address_prefix = "10.0.2.0/24"
  }

  subnet {
    name           = "subnet3"
    address_prefix = "10.0.3.0/24"
  }
}

Argument Reference

The following arguments are supported:

subscription_id - (Optional) The subscription ID to use. It can also be sourced from the ARM_SUBSCRIPTION_ID environment variable.
client_id - (Optional) The client ID to use. It can also be sourced from the ARM_CLIENT_ID environment variable.
client_secret - (Optional) The client secret to use. It can also be sourced from the ARM_CLIENT_SECRET environment variable.
tenant_id - (Optional) The tenant ID to use. It can also be sourced from the ARM_TENANT_ID environment variable.

Creating Credentials

Azure requires that an application is added to Azure Active Directory to generate the client_id, client_secret, and tenant_id needed by Terraform (subscription_id can be recovered from your Azure account details).

Using the 'Classic' Portal:

Select Active Directory from the left pane and select the directory you wish to use
Select Applications from the options at the top of the page
Select Add from the bottom of the page. Choose Add an application my organization is developing
Add a friendly name for the application e.g. Terraform. Leave Web Application And/Or Web API selected and click the arrow for the next page
Add two valid URIs. These aren't used an can be anything e.g. http://terra.form. Click the arrow to complete the wizard
You should now be on the page for the application. Click on Configure at the top of the page. Scroll down to the middle of the page where you will see the value for client_id
In the Keys section of the page, select a suitable duration and click Save at the bottom of the page. This will then display the value for client_secret. This will disappear once you move off the page
Click View Endpoints at the bottom of the page. This will display a list of URIs. Extract the GUID from the bottom URI for OAUTH 2.0 AUTHORIZATION ENDPOINT. This is the tenant_id

To enable the application for use with Azure RM, you now need to switch to the 'New' Portal:

Select Subscriptions from the left panel. Select the subscription that you want to use. In the Subscription details pane, click All Settings and then Users
Click Add and then select an appropriate role for the tasks you want to complete with Terraform. You can find details on the built in roles here
Type in the name of the application added in the 'Classic' Portal. You need to type this as it won't be shown in the user list. Click on the appropriate user in the list and then click Select
Click OK in the Add Access panel. The changes will now be saved

Microsoft have a more complete guide in the Azure documentation: Create Active Directory application and service principle

Testing

Credentials must be provided via the ARM_SUBSCRIPTION_ID, ARM_CLIENT_ID, ARM_CLIENT_SECRET and ARM_TENANT_ID environment variables in order to run acceptance tests.
