Creating Network Resources in Azure with Terraform

Hey, Gurus! Welcome to the Creating Network Resources in Azure with Terraform lab. In this lab, we will cover these 4 objectives:

1. First, we will log into the Azure Portal and configure the Cloud Shell, and then download and run the lab setup script to setup the lab.
1. Second, we will import the resource group.
1. Third, we will add the virtual network, subnet, and a network security group.
1. And for the fourth objective, we will add a load balancer.

These are resources that will be the foundation for VMs and other resources.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Set Up Cloud Shell and the Lab Environment

In the Portal

Go to the Azure Portal and log in using your lab credentials.
Click the Cloud Shell icon next to the search bar in the Portal.
Select Bash at the prompt.
Click Show Advanced Settings.
Set the Cloud Shell region to the same location as the resource group.
Select the existing resource group, and select Use Existing for the storage account.
In the File share section, choose Create new and enter terraform.
Click Attach Storage.
Download the lab_4_setup.sh script at https://raw.githubusercontent.com/ACloudGuru/advanced-terraform-with-azure/main/lab_network_resources/lab_4_setup.sh.
Add execute permissions to the script.
Run the [lab_4_setup.sh]() script.

Import the Resource Group into Terraform

In the Cloud Shell

1.. In the Cloud Shell, review the networking.tf file.

Make note of the resource group name and label at the top and then close the file.
Run the az group list command to get the subscription ID.
Import your resource group into Terraform using the resource name, label, and subscription ID.
After the import, add the name and location of your resource group to the networking.tf file so it looks like the code below (fill in with your resource group and location):
```
resource "azurerm_resource_group" "guru" {
    name     = "<RESOURCE_GROUP>"
    location = "<LOCATION>"
}   
```
Save the file.

Add the Networking Configuration

In the Cloud Shell

Edit the networking.tf file.
Add a virtual network with the label comics, the name vnet, and an address space of 10.0.0.0/16.
Add a subnet with the label comics, the name subnet, and an address prefix of 10.0.2.0/24.
Add a public IP with the label comics, the name publicIpForLB, and an allocation method of Static .
Save the changes.

Add the Load Balancer Configuration

1) Create a file called lb.tf.
2) Add the load balancer configuration with the label comics, the name loadBalancer, and a frontend IP configuration that uses the public IP you created in the networking.tf file.
3) Add the load balancer backend address pool configuration with the label comics and the name BackendAddressPool.
4) Save the changes.

Apply the Configuration

Validate your Terraform configuration.
Apply your configuration.
Confirm your resources were deployed to Azure.
