Tutorial:

Create a load balancer with an availability set in the backend pool using the Terraform.

This Terraform task creates a load balancer and availability set.

In this task we have :

A Resource Group, Storage Account, virtual machines in an availability set, load balancer with 80 (HTTP) and 443 (HTTPS) rules, Virtual Network, 3 Subnets, 2 data disks, 2 os disks, a Public IP.

variable :

       variable "arm_region" 
       description = "The Azure region to create things in."

       variable "arm_vm_admin_password" 
       description = "Passwords for the root user in VMs."

       variable "arm_frontend_instances" 
       description = "Number of front instances"

First of all in this Task we will be creating and configuring the resources below :

Resource group name is "oguzhanRG" in the "West US" location.

Storage account name is "oaydoganstorageacc" in the Resource group we just created.

Virtual network name is "tf-vnet"

Subnet names are "frontend", "backend" and "dmz"

Virtual Machines in availability set name is "tf-avail-set".

Second of all in this Task we will be creating and configuring the resources below :

Load Balancer name is "tf-lb"

                          Rule 1 :                 resource "azurerm_lb_probe" "port80" {
                                                   name                    = "tf-lb-rule-80"
                                                   protocol                       = "Tcp"
                                                   frontend_port                  = 80
                                                   backend_port                   = 80
                                                   frontend_ip_configuration_name = "default"

                          Rule 2 :                 resource "azurerm_lb_rule" "port443" {
                                                   name                    = "tf-lb-rule-443"
                                                   protocol                       = "Tcp"
                                                   frontend_port                  = 443
                                                   backend_port                   = 443
                                                   frontend_ip_configuration_name = "default"

Health probe for HTTP

Health proble for HTTPS

Public IP name is "tf-public-ip", allocation_method set as = "Static"

Backend pool for availability set.

Third of all in this Task we will be creating and configuring the resources below :

                         Outputs :
                                                    output "frontend_id" 
                                                    output "backend_id" 
                                                    output "dmz_id" 
                                                    output "load_balancer_ip"

Allow me to export structured data about my resources.

Finally in this Task we will be creating and configuring the resources below :

We will keep our tfstate file in the container, named "oaydogancontainer"
