Introduction to Kubernetes

Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It was originally developed by Google and is now maintained by the Cloud Native Computing Foundation (CNCF). Kubernetes provides a powerful and flexible framework for managing containers, making it an essential tool for modern application development and deployment.

Setting up a Kubernetes Cluster on AWS

In this section, we'll guide you through the process of setting up a Kubernetes cluster on AWS using the managed Kubernetes service, Amazon Elastic Kubernetes Service (EKS).

Prerequisites

Before we begin, make sure you have the following:

• an AWS account
• AWS CLI installed and configured
• kubectl installed
• eksctl installed

Creating a Kubernetes Cluster with eksctl

eksctl is a command-line tool that simplifies the process of creating and managing Kubernetes clusters on AWS. To create a new cluster, run the following command:

eksctl create cluster --name my-cluster --region us-west-2 --nodes 3

This command creates a new Kubernetes cluster named my-cluster in the us-west-2 region with three worker nodes. It may take a few minutes for the cluster to be created.

Configuring kubectl to Use Your Cluster

Once your cluster is created, you need to configure kubectl to use it. Run the following command:

aws eks update-kubeconfig --region us-west-2 --name my-cluster

This command updates your kubectl configuration to use the new cluster.
