+# Quickstart: Create a Azure NAT Gateway using Terraform
+
+This article shows how to use Terraform to create a resource group, a virtual network with a subnet, a public IP address, a NAT gateway, a network security group with a rule, a network interface, a storage account, and a Linux virtual machine in Azure. 
+
+The script also generates a random SSH public key and associates it with the virtual machine for secure access. The public key is outputted at the end of the script execution. 
+
+The script uses the Random and AzAPI providers in addition to the AzureRM provider. The Random provider is used to generate a unique name for the resource group and the SSH key. The AzAPI provider is used to generate the SSH public key. 
+
+As with the public key, the names of the created resource group, virtual network, subnet, and NAT gateway are printed when the script is run.

+
+## Prerequisites
+
+- An Azure account with an active subscription. You can [create an account for free](https://azure.microsoft.com/free/?WT.mc_id=A261C142F).
+
+- [Install and configure Terraform](/azure/developer/terraform/quickstart-configure)
+
+## Implement the Terraform code
+
+> [!NOTE]
+> The sample code for this article is located in the [Azure Terraform GitHub repo](https://github.com/Azure/terraform/tree/master/quickstart/101-nat-gateway-create). You can view the log file containing the [test results from current and previous versions of Terraform](https://github.com/Azure/terraform/tree/master/quickstart/101-nat-gateway-create/TestRecord.md).
+> 
+> See more [articles and sample code showing how to use Terraform to manage Azure resources](/azure/terraform)
+
+1. Create a directory in which to test and run the sample Terraform code and make it the current directory.
+
+1. Create a file named `main.tf` and insert the following code:
+
+    :::code language="Terraform" source="~/terraform_samples/quickstart/101-nat-gateway-create/main.tf":::
+
+1. Create a file named `outputs.tf` and insert the following code:
+
+    :::code language="Terraform" source="~/terraform_samples/quickstart/101-nat-gateway-create/outputs.tf":::
+
+1. Create a file named `providers.tf` and insert the following code:
+
+    :::code language="Terraform" source="~/terraform_samples/quickstart/101-nat-gateway-create/providers.tf":::
+
+1. Create a file named `ssh.tf` and insert the following code:
+
+    :::code language="Terraform" source="~/terraform_samples/quickstart/101-nat-gateway-create/ssh.tf":::
+
+1. Create a file named `variables.tf` and insert the following code:
+
+    :::code language="Terraform" source="~/terraform_samples/quickstart/101-nat-gateway-create/variables.tf":::
+
+
+## Initialize Terraform

+
+## Create a Terraform execution plan

+
+## Apply a Terraform execution plan

+
+## Verify the results
+
+#### [Azure CLI](#tab/azure-cli)
+
+1. Get the Azure resource group name.
+
+    ```console
+    resource_group_name=$(terraform output -raw resource_group_name)
+    ```
+
+1. Get the NAT gateway ID.
+
+    ```console
+    nat_gateway=$(terraform output -raw nat_gateway)
+    ```
+
+1. Run [az network nat gateway show](/cli/azure/network/nat/gateway#az-network-nat-gateway-show) to display the details about the NAT gateway.
+
+    ```azurecli
+    az network nat gateway show --resource-group $resource_group_name \
+                                --ids $nat_gateway
+        
+    ```
+
+#### [Azure PowerShell](#tab/azure-powershell)
+
+1. Get the Azure resource group name.
+
+    ```console
+    $resource_group_name=$(terraform output -raw resource_group_name)
+    ```
+
+1. Get the NAT gateway ID.
+
+    ```console
+    $nat_gateway=$(terraform output -raw nat_gateway)
+    ```
+
+1. Run [Get-AzNatGateway](/powershell/module/az.network/get-aznatgateway) to display the the details about the NAT gateway.
+
+    ```azurepowershell
+    Get-AzNatGateway -ResourceGroupName $resource_group_name `
+                     -Name $nat_gateway
+    ```
