This blog focuses on creating Pods in AWS using EKS Clusters and Linux terminals

And is a initial guide to spin up VMs and configure Kubernetes on AWS

Cautiously optimistic and Self-reliant methods to save our time as Advocates/Architects on the Cloud for initial commits and setups

Here is my live demo video and help guide for AWS EKS

Core concepts to be aware about are

Amazon EKS (Elastic Kubernetes Service)

Amazon Elastic Compute Cloud (EC2)

Amazon Virtual Private Cloud (VPC)

AWS Identity and Access Management (IAM)

To get started with Amazon EKS ,you need to create an Amazon EKS cluster and then launch worker nodes into your cluster. You can do this using the AWS Management Console, AWS CLI, or programmatically using AWS SDKs or Infrastructure as Code (IaC) tools like Terraform and CloudFormation. Once your cluster is up and running, you can use standard Kubernetes tools and APIs to deploy and manage your applications.

EC2 offers users persistent storage and elastic IP addresses while being fault-tolerant thanks to Amazon’s engineering of Availability Zones insulated from other availability zones. There are multiple ways to pay for EC2 instances such as On-Demand, Savings Plans, Reserved Instances, and Spot Instances based on each use-case and budget.

VPC service provides users with the option to assign IP addresses of their choosing from one or more subnets, giving them granular control over security by choosing which AWS resources are public facing or not. VPC allows users to connect to the internet, a user’s corporate data center, and other users’ VPCs. The security of AWS VPC is ensured through the use of security groups as a firewall to control traffic at the instance level, and network access control lists as a firewall to control traffic at the subnet level.

With IAM, you can create and manage AWS users and groups, set permissions for resources, control access to AWS services, and manage multiple users and their level of access to AWS resources from a single AWS account. IAM provides various features, such as multi-factor authentication, password policies, and permissions boundaries, to help you manage access securely.

Prerequisites for AWS EKS on your Linux PC or Server include

  • kubectl
  • eksctl
  • AWS Free account for initial setup

These are steps followed by me on AWS Console for AWS EKS using Linux OS terminal

Step 1

Install AWS CLI on your computer or server via CLI

Run the command

Lsb_release -a

Refer here for more information

This is to find which distro of Linux is available on your system. And to check if aws cli will work with the Ubuntu/RedHat/Debian OS kernels

Next run the command

Uname -m

This will display the CPU type of your machine

The command uname -m prints the machine hardware name. On Linux, this field comes from the machine member of struct utsname, as populated by the uname(2) system call. The possible values for the “machine” field can vary depending on the architecture and sub-architectures of the system. On most Linux systems, the output of uname -m will be one of the following:

  • x86_64: 64-bit Intel/AMD (most modern desktops and laptops)
  • i686: 32-bit Intel/AMD (older desktops and laptops)
  • aarch64: 64-bit ARM (most modern mobile devices)
  • armv7l: 32-bit ARM (older mobile devices)

To check what machine hardware name is printed on your specific system, you can run the command uname -m in your terminal.

For more information go to “Installing or updating the latest version of the AWS CLI

Finally run the snap package command

Snap install aws-cli –classic

To install aws-cli to your machine

To verify installation was successful


aws help

You should be able to see help docs in your terminal on success

Shift+q to come back to your commandline

And proceed with installing kubectl.

Step 2

Installing kubectl via CLI

Go to the official doc.aws titled “Install and Set Up kubectl on Linux

And under — other package management section. You will find instructions to install kubectl using snap packages

Run the command

snap install kubectl — classic

To check if kubectl installation was successful



You should be able to see help page of kubectl on your terminal

Next, move to installation of eksctl.

Step 3

Installing eksctl via CLI

Refer to official documentation on aws.docs i.e “Installing or updating eksctl

Click the link for git instructions in the page. You should be directed to “eksctl — The official CLI for Amazon EKS

For Linux use Unix installation code snippets, be sure to use them line by line in your terminal.

Refer to my video instruction in case you are stuck.

To make sure it was properly installed



You should be able to see Help page for eksctl on your terminal

Step 4

Make favourites on AWS Console and create UserGroup for permissions to CLI

Search and Favourite the following Services from AWS

  • VPC — virtual private cloud
  • EC2 — elastic compute cloud
  • EKS — elastic kubernetes service
  • IAM — identity and access management

Step 4 a:

Set up User Groups in AWS IAM

Click User groups under the Access Management menu on the left plane.

Then click on “Create group” button

Enter the group name in “User group name” textbox eks-admin

Scroll down and click “Create group”

Next lets set up access permissions to access the user group via CLI

Go into the eks-admin group which you have created

Under the permissions tab click drop-down — “Add permissions”

Select — Attach Policies

In the search bar that appears ; search and select “administratoraccess”

Click checkbox to select and then click Add permissions at the bottom of the Tab

Step 4b

Set up User in AWS IAM

On the left menu pane under Access Management click Users.

On the Users page click on the “Add users” button

Type in a username (For Ex. eks-[yourname])in the textbox.

Click Next

In the Permissions options tab select

“Add user to group”

Select checkbox for “eks-admin” and click Next

Add tags to your user i.e Name:Value as appropriate (For Ex. project:aws-eks)

Finish up by clicking on Create User


Copy the “User arn” value and paste in notepad for future reference. — this is shown in the video

Step 4c

Set up AccesskeyID and Accesskey for your User

Click on “Security credentials” tab and scroll down to access keys section

Create access key

Select the CLI option

And follow the steps

Download .csv file and keep it for reference to set up your access to AWS Console from your pc or server via CLI

Step 5

Set up region in AWS to operate and user credentials generated previously to link to your pc or server

Make the decision on region selection by going through the available region Service endpoints in this link


Choose a region closest to you for minimal costs

Make a note of the region you have decided on. — Refer the video

Step 5a

Configure your CLI to connect to AWS Console

Open your terminal on your PC or Server

Run the command

aws configure

Enter the AWS Access key ID from the downloaded csv

Enter the Secret Access key from the downloaded csv

Enter the Default region name from the previous step

Leave the Default output format as it is and click Enter

To verify all the above setup is working

Check your HOME directory

It should have a folder name “.aws”

Check files for your configuration and credentials as well.

Refer the Video for more information on how

Step 6

Create an EKS cluster with eksctl

We will be using YAML manifest to Infrastructure as Code (IaC) for initial basic set up

Sample file available in github here

Refer to the video for Line-by-Line instructions

The .yaml file will set up 3 nodes as m5.large instances on the pod or pods depending on Traffic needed or load balancing in your region.

Run the command

Eksctl create cluster -f cluster.yaml

The spin-up will take 30 mins or more

Check the AWS Console by clicking your favorites AWS EKS and see the cluster you created running on your region.

Step 7

Run kubectl on your CLI to see how the cluster is functioning

On your PC or Server run the below command

kubectl config get-contexts

This should display the namespace(s) of your node(s)

To view the Pods running

Run the command

Kubectl get pods -A

This should display a list of all the pods running in the cluster

To view the nodes run the command

Kubectl get nodes

This should display the list of nodes

Note: name column indicates the IP in your Virtual Private Network for these nodes.

Version column should display the version of Kubernetes

So we are done with our AWS-EKS cluster creation within few minutes

Will be posting more cloud configuration contents in the coming blogs

Until next time…
