This template deploys an [Azure Front Door (classic)](https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/frontdoor).
## Resources
## Terraform resource types
| Terraform Resource Type | Description |
| - | - |
| `azurerm_resource_group` | The resource group for all the deployed resources. |
| `azurerm_frontdoor` | The Front Door (classic). |
| `random_id` | A random identifier generator to generate a unique Front Door resource name. |
- [random_pet](https://registry.terraform.io/providers/hashicorp/random/latest/docs/resources/pet)
- [azurerm_resource_group](https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/resource_group)
- [random_id](https://registry.terraform.io/providers/hashicorp/random/latest/docs/resources/id)
- [azurerm_frontdoor](https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/frontdoor)
## Variables
| Name | Description | Default Value |
|-|-|-|
| `location` | The location for all the deployed resources. | `westus2` |
| `resource_group_name` | The name of the resource group to deploy. | `FrontDoor` |
| `backend_address` | The host name or IP address of the backend application. | |
| `resource_group_name_prefix` | Prefix of the resource group name that's combined with a random ID so name is unique in your Azure subscription. | rg |
| `resource_group_location` | Location of the resource group. | eastus |
| `backend_address` | The host name or IP address of the backend application. | www.bing.com |
## Example
```bash
$ terraform plan -out main.tfplan
Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
+ create
Terraform will perform the following actions:
