EKS Cluster Tutorial

In this tutorial I want to explain how to setup EKS kubernetes in detail.

Prerequisites: AWS Account 

You can follow the steps below:

  • Whats EKS
  • General Architecture
  • Create IAM user + SSH Keys + Access Keys
  • EKS Service Role
  • Create VPC + Subnets
  • Create EKS Control Plane
  • Command Line CLI tools

1- What is EKS : Amazon Elastic Container Service for Kubernetes (Amazon EKS) is a managed service that makes it easy for you to run Kubernetes on AWS without needing to stand up or maintain your own Kubernetes control plane.

2-General Architecture: To achieve high availability in you Kubernetes clusters, you have to run at least three Kubernetes masters across different AZs.

AZs like in the below picture (AZ-1, AZ-2, AZ-3)

Every availibility zone needs to have members like Master-Node, ETCD, K8s Worker Nodes

AWS Managed: Master-Node, ETCD

User Managed: Worker-Nodes


Kubernetes API is exposed via the Amazon EKS endpoint associated with your cluster.

AZs members

Worker Nodes is a place where your applications run on it and generally runs in autoscaling groups accross Availability Zones

  • 3- Create IAM User: We need to create Policy 

EKS Control Plane features:

  • Control Plane is highly available
  • Single tenant (not share with other customers)
  • Made of AWS components (EC2, ELB, ASG, VPC)
  • The whole control plane is fronted by NLB (has static IP)

to be continue ….
