<ul><li>Kubernetes (K8s) is a container orchestration platform that helps deploy, scale, and manage containerized applications. One way to manage a Kubernetes cluster is using kubeadm on AWS EC2 instances.</li><li>In this guide, we will set up a Kubernetes cluster with one master node and one worker node.</li><li>The master and worker nodes use Ubuntu 20.04 or newer as the OS. Open port 6443 on the master node.</li><li>Docker, kubeadm, kubelet, and kubectl are the essential tools required to set up the cluster.</li><li>Start by launching the two EC2 instances: one t2.large instance as the master node and one t2.medium instance as the worker node.</li><li>Update and upgrade both nodes, install Docker, kubeadm, kubelet, kubectl, and initialize the master node.</li><li>Add the worker node to the cluster, verify the cluster, and deploy the Nginx pod.</li><li>This setup provides a foundation for experimenting with advanced Kubernetes features and workloads.</li><li>Overall, building a Kubernetes cluster using kubeadm is a straightforward process that lets you deploy, scale, and manage containerized applications efficiently.</li><li>Author: Vansh Kapoor</li></ul>
