What is Amazon EKS?

Amazon EKS is a fully managed container orchestration service. EKS allows you to quickly deploy a production-ready Kubernetes cluster in AWS, deploy and manage containerized applications more easily with a fully managed Kubernetes service.

EKS takes care of the master node/control plane. We need to create worker nodes.

EKS cluster can be created in the following different ways:

1. AWS console


3. eksctl command

4. using Terraform

We will create an EKS cluster using eksctl command line tool.


  • Install AWS CLI:

      curl "" -o ""
      sudo apt install unzip
      sudo ./aws/install
      aws --version
  • Install eksctl:

      curl --silent --location "$(uname -s)_amd64.tar.gz" | tar xz -C /tmp
      sudo mv /tmp/eksctl /usr/local/bin
      eksctl version
  • Install kubectl:

      curl -LO "$(curl -L -s"
      sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
      kubectl version

Create IAM Role with Administrator Access:-

You need to create an IAM role with the AdministratorAccess policy.
Go to the AWS console, IAM, and click on Roles. create a role

Select AWS services, Click EC2, and Click on Next permissions.

Now search for AdministratorAccess policy and click

Skip on creating a tag.
Now give a role name and create it.

Assign the role to the EC2 instance:

Go to the AWS console, click on EC2, select EC2 instance, and Choose Security.
Click on Modify IAM Role.

Choose the role you have created from the dropdown.
Select the role and click on Apply.

Let's Create an EKS Cluster

Create EKS Cluster with two worker nodes using eksctl:

eksctl create cluster \
             --name MyEKS \
             --version 1.22 \
             --region us-east-2 \
             --nodegroup-name my-worker-nodes \
             --node-type t2.micro \
             --nodes 2

The above command should create an EKS cluster in AWS, it might take 15 to 20 mins. The  eksctl  tool uses CloudFormation under the hood, creating one stack for the EKS master control plane and another stack for the worker nodes.

This should confirm that the EKS cluster is up and running.

eksctl get cluster --name MyEKS --region us-east-2

Update the Kube config by entering the below command:

aws eks update-kubeconfig --name MyEKS --region us-east-2

you can view the kubeconfig file by entering the below command:

cat /var/lib/jenkins/.kube/config

Connect to EKS cluster using kubectl commands:

To view the list of worker nodes as part of the EKS cluster.

kubectl get nodes

To view the NameSpaces:

kubectl get ns

Deploy Nginx on a Kubernetes Cluster

Let us run some apps to make sure they are deployed to the Kubernetes cluster. The below command will create a deployment.

apiVersion: apps/v1
kind: Deployment
  name: nginx
    app: nginx
  replicas: 2
      app: nginx
        app: nginx
      - name: nginx
        image: nginx:1.14.2
        - containerPort: 80

View Deployments:

kubectl get deployments

Delete EKS Cluster using eksctl

eksctl delete cluster --name MyEKS --region us-east-2


Login to AWS console --> AWS Cloud formation --> delete the stack manually.

you can also delete the cluster under AWS console --> Elastic Kubernetes Service---> Clusters --> Click on Delete cluster.


I hope this can help get you started with Kubernetes right away so that you can begin building and deploying applications on the AWS EKS cluster.

In the future, I would like to write articles about using Kubernetes with Terraform (such as Kubernetes provider and helm provider), whether the cluster was created with Terraform or not. This way, you can develop a modular infrastructure script, unladen with unnecessarily complex scripts.

Best of success with your Kubernetes adventures. Enjoy!
