Setup Kubernetes on Amazon EKS

You can follow same procedure in the official AWS document Getting started with Amazon EKS – eksctl

Pre-requisites:

• an EC2 Instance

AWS EKS Setup

1. Setup kubectl
   a. Download kubectl version 1.20
   b. Grant execution permissions to kubectl executable
   c. Move kubectl onto /usr/local/bin
   d. Test that your kubectl installation was successful

   curl -o kubectl https://amazon-eks.s3.us-west-2.amazonaws.com/1.19.6/2021-01-05/bin/linux/amd64/kubectl
   chmod +x ./kubectl
   mv ./kubectl /usr/local/bin 
   kubectl version --short --client

2. Setup eksctl
   a. Download and extract the latest release
   b. Move the extracted binary to /usr/local/bin
   c. Test that your eksclt installation was successful

   curl --silent --location "https://github.com/weaveworks/eksctl/releases/latest/download/eksctl_$(uname -s)_amd64.tar.gz" | tar xz -C /tmp
   sudo mv /tmp/eksctl /usr/local/bin
   eksctl version

3. Create an IAM Role and attache it to EC2 instance
   Note: create IAM user with programmatic access if your bootstrap system is outside of AWS
   IAM user should have access to
   IAM
   EC2
   VPC
   CloudFormation

4. Create your cluster and nodes

   eksctl create cluster --name cluster-name  \
   --region region-name \
   --node-type instance-type \
   --nodes-min 2 \
   --nodes-max 2 \ 
   --zones <AZ-1>,<AZ-2>
   
   example:
   eksctl create cluster --name valaxy-cluster \
      --region ap-south-1 \
   --node-type t2.small \

5. To delete the EKS clsuter

   eksctl delete cluster valaxy --region ap-south-1

6. Validate your cluster using by creating by checking nodes and by creating a pod

   kubectl get nodes
   kubectl run pod tomcat --image=tomcat
