⇒ In this guide, we will walk through the step-by-step process of setting up a Kubernetes cluster on AWS EC2 instances, from launching instances to joining worker nodes to the master. This tutorial is beginner-friendly and provides a structured approach to Kubernetes setup.

Step 1: Setting Up AWS Instances

Before setting up Kubernetes, we need to launch EC2 instances on AWS.

1.1 Launch Three EC2 Instances on AWS

• Login to your AWS account.
• Go to EC2 Dashboard → Click on Launch Instance.
• Select Ubuntu (t2.medium) as the OS image.
  • The Master Node must have at least 2 vCPUs and 4GB RAM for smooth operation.
  • The Worker Nodes can have similar configurations.
• Launch three instances:
  • 1 Master Node
  • 2 Worker Nodes

1.2 Configure SSH Access

• Create a private key using puttygen (if using Windows) or use the AWS-provided .pem key.
• Access the three instances using SSH (Putty on Windows, Terminal on Linux/Mac).

Step 2: Install Required Packages on All Nodes (Master & Workers)

After accessing the instances, we need to install Docker, Kubernetes, and some required dependencies.

2.1 Update System Packages

sudo su
apt-get update

This ensures all system packages are up to date.

2.2 Install HTTPS Transport Package
