Step - 1 : Create EKS Management Host in AWS

  1. Launch new Ubuntu VM using AWS Ec2 ( t2.micro )
  2. Connect to machine and install kubectl using below commands
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
sudo mv ./kubectl /usr/local/bin
kubectl version --short --client
  1. Install AWS CLI latest version using below commands
sudo apt install unzip
curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install
aws --version
  1. Install eksctl using below commands
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

Step - 2 : Create IAM role & attach to EKS Management Host

  1. Create New Role using IAM service ( Select Usecase - ec2 )

  2. Add below permissions for the role

    • IAM - fullaccess
    • VPC - fullaccess
    • EC2 - fullaccess
    • CloudFomration - fullaccess
    • Administrator - acces

  3. Enter Role Name (eksroleec2)

  4. Attach created role to EKS Management Host (Select EC2 => Click on Security => Modify IAM Role => attach IAM role we have created)

Step - 3 : Create EKS Cluster using eksctl

Syntax:

eksctl create cluster --name cluster-name
--region region-name
--node-type instance-type
--nodes-min 2
--nodes-max 2 \ --zones ,

N. Virgina:

eksctl create cluster --name ashokit-cluster4 --region us-east-1 --node-type t2.medium --zones us-east-1a,us-east-1b

Mumbai:

eksctl create cluster --name ashokit-cluster4 --region ap-south-1 --node-type t2.medium --zones ap-south-1a,ap-south-1b

Note: Cluster creation will take 5 to 10 mins of time (we have to wait). After cluster created we can check nodes using below command.

kubectl get nodes

Note: We should be able to see EKS cluster nodes here.**

We are done with our Setup

Step - 4 : After your practise, delete Cluster and other resources we have used in AWS Cloud to avoid billing

eksctl delete cluster --name ashokit-cluster4 --region ap-south-1
