Installing Amazon EKS on AWS: A Complete Guide
How to Install Amazon EKS on AWS: A Step-by-Step Guide
Introduction
Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes service that makes it easy to run Kubernetes on AWS without needing to install and operate your own Kubernetes control plane or nodes. In this guide, we will walk you through the process of installing EKS on AWS, ensuring you’re set for success in deploying Kubernetes clusters in the cloud.
Prerequisites
- AWS Account: Ensure you have an AWS account set up with appropriate permissions, specifically AWS IAM roles for Kubernetes service and node management.
- AWS CLI: Install the AWS Command Line Interface (AWS CLI) (Official site) on your local system.
- kubectl: Ensure kubectl, the Kubernetes command-line tool, is installed and configured on your machine.
- eksctl: Install eksctl (Official site), a simple CLI tool for creating and managing EKS clusters.
Step 1: Configure AWS CLI
Begin by configuring your AWS CLI with the command:
aws configureEnter your AWS Access Key, Secret Key, region, and output format when prompted.
Step 2: Create EKS Cluster
Use eksctl to create your cluster with a single command:
eksctl create cluster --name my-cluster --region us-west-2This command sets up the EKS cluster in the specified region, deploying the Kubernetes Master nodes and connecting worker nodes.
Step 3: Update kubeconfig
After the cluster is created, update your kubeconfig file to enable kubectl interaction with your new EKS cluster:
aws eks update-kubeconfig --region --name my-clusterStep 4: Verify the EKS Cluster
Check the cluster status to ensure everything is functioning as expected:
kubectl get svcVerify that your Kubernetes services are running. You should see the Kubernetes dashboard and default service entries.
Troubleshooting Common Issues
If you encounter issues during setup:
- Permissions: Double-check that your AWS IAM roles have the necessary permissions for EKS.
- Outdated Tools: Ensure all CLI tools (AWS CLI, kubectl, eksctl) are up-to-date.
- Resource Limits: Confirm that your AWS account has sufficient limits for the required resources.

Summary Checklist
- Configure AWS CLI
- Create EKS Cluster using eksctl
- Update kubeconfig for kubectl
- Verify cluster status with kubectl commands
- Troubleshoot permission and resource issues if necessary
Following these steps will set up a fully functional EKS cluster on AWS, ready for deploying containerized applications.
