Setting up and Deploying Applications on Amazon EKS

A Comprehensive Guide

This article provides a comprehensive guide to setting up and deploying applications on Amazon Elastic Kubernetes Service (EKS). It covers configuring the worker nodes and control plane, and deploying applications using various tools and best practices.

Amazon Elastic Kubernetes Service (EKS)

  1. Configuring worker nodes and control planes
  2. Deploying applications to EKS

Introduction

Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes service that makes it easy to deploy, manage, and scale containerized applications. This article will guide you through the process of configuring worker nodes and control planes, and deploying applications to EKS.

Setting up the control plane and worker nodes is crucial. The control plane manages the Kubernetes cluster, while worker nodes run your applications. This usually involves using the AWS Management Console or the AWS CLI.

aws eks update-cluster-version
 --name my-cluster
 --desired-version 1.24
Do You Know? You can use CloudFormation or Terraform to automate the infrastructure provisioning for your EKS cluster.

Ensure your worker nodes have the necessary networking and security configurations. Proper IAM roles are essential for access control.

Important Note: Always use appropriate security groups and IAM roles to limit access to your EKS cluster.

Once your EKS cluster is up and running, you can deploy your applications using kubectl. This involves creating Kubernetes manifests (YAML files) that define your deployments, services, and other resources.

Avoid This: Avoid deploying directly to the master node. Always deploy your applications to worker nodes.

You can use tools like Helm to simplify the deployment process. Helm manages Kubernetes charts, which are pre-packaged deployments.

helm install my-app my-chart

Summary

  • Configured worker nodes and control planes.
  • Successfully deployed applications to the EKS cluster.
  • Emphasized the importance of security and access control.
  • Used kubectl and Helm for efficient application management.
