EKS Cluster and AWS Load Balancer Controller Setup

Network Architecture which we are going to deploy

I use makefile to simplify running Command

A Makefile is a powerful tool that simplifies the process of managing and automating complex tasks in software development and system administration. It serves as a build automation tool that orchestrates the execution of commands to streamline the development, deployment, and maintenance processes.

Before running the Makefile, ensure that you have the following prerequisites:

eksctl installed
kubectl installed
AWS CLI installed and configured
Helm installed
A valid SSH key pair for SSH access to the nodes

Create EKS Cluster:
```
make create_cluster
```
Deploy Private Node Group:
```
make deploy_private_nodegroup
```
Create OIDC:
```
make create_oidc
```
Create Load Balancer IAM Policy:
```
make create_lb_policy
```
Create Service Account:
```
make create_service_account
```
Install AWS Load Balancer Controller:
```
make install_aws_loadbalancer
```
