What is Amazon EKS ?

Amazon Elastic Kubernetes Service (Amazon EKS) is a managed service provided by Amazon Web Services (AWS) that makes it easier to run Kubernetes clusters in the cloud. Kubernetes is an open-source container orchestration platform that helps manage and scale containerized applications.

With Amazon EKS, you can deploy, manage, and scale your applications using Kubernetes without having to worry about the underlying infrastructure. Amazon EKS takes care of the control plane, which includes the management of the Kubernetes master nodes, and you can focus on deploying and managing your containerized applications.

Features and Benefits of Amazon EKS

Managed Kubernetes Control Plane: Amazon EKS manages the Kubernetes control plane, including the etcd cluster, ensuring high availability and scalability. You don’t need to worry about managing the control plane infrastructure.
Integration with AWS Services: Amazon EKS integrates seamlessly with other AWS services, such as Elastic Load Balancing, Amazon RDS, AWS Identity and Access Management (IAM), Amazon VPC, and more, making it easier to build and run containerized applications.
Security and Compliance: Amazon EKS provides security features, such as VPC networking isolation, IAM integration, encryption at rest and in transit, and support for security groups and network policies. This helps you meet security and compliance requirements.
Automatic Scaling: You can scale your Kubernetes applications on Amazon EKS by adding or removing worker nodes based on demand. This allows your applications to handle increased traffic and workload without manual intervention.
Application Observability: Amazon EKS integrates with AWS monitoring and logging services, such as Amazon CloudWatch, AWS X-Ray, and AWS CloudTrail, allowing you to gain insights into the performance and behavior of your applications.
High Availability: Amazon EKS provides multi-AZ deployment options, allowing you to distribute your worker nodes across multiple availability zones for enhanced availability and fault tolerance.

To use Amazon EKS, you need to create an Amazon EKS cluster, which consists of a control plane and worker nodes. The control plane runs in an Amazon EKS-managed Kubernetes control plane, while the worker nodes are EC2 instances that run your containerized applications.

Overall, Amazon EKS simplifies the process of running Kubernetes on AWS, provides scalability, security, and integrates well with other AWS services, making it a popular choice for managing containerized applications in the cloud.

#1:Install eksctl CLI tool for creating EKS Clusters on AWS

Use below command to download eksctl CLI tool for creating EKS Clusters on AWS, To download latest eksctl tool visit eksctl official github page

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

move eksctl setup to /usr/local/bin directory

sudo mv /tmp/eksctl /usr/local/bin

To check eksctl version

eksctl version

Below are eksctl help commands

eksctl --help

eksctl create cluster --help

eksctl create cluster [command] --help

#2:Install Kubectl on Ubuntu

Add the kubectl GPG key

curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -

Create apt repo for kubectl

sudo touch /etc/apt/sources.list.d/kubernetes.list

Add Kubernetes official apt repo

echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee -a /etc/apt/sources.list.d/kubernetes.list

Update the system packages

sudo apt-get update

Install kubectl on Ubuntu using below command

sudo apt-get install -y kubectl

#3:Install AWS CLI on Ubuntu

Download the aws cli bundle using below command

 sudo curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"

Install the unzip and python on Ubuntu if not installed

 sudo apt install unzip python

Extract the aws cli bundle setup

 sudo unzip unzip awscliv2.zip

Configure the AWS CLI on Ubuntu

sudo ./aws/install

Verify the AWS CLI version

aws --version

Output:

aws-cli/1.18.97 Python/2.7.18rc1 Linux/5.4.0-1015-aws botocore/1.17.20

#4:Create AWS Access Key ID and Secret Access Key

Now create AWS Access Key ID and Secret Access Key ID

Go to the security credentials
Then click on create access key

#5:Configure AWS CLI

To connect AWS using CLI we have configure AWS user using below command

aws configure

it will ask AWS Access Key ID, AWS Secret Access Key, Default region name, Default output format

AWS Access Key ID [None]: *********7G
AWS Secret Access Key [None]: ***********************px
Default region name [None]: ap-south-1
Default output format [None]: json

Now you have connected your aws account using AWS CLI.

#6:Create Amazon EKS cluster using eksctl

Create Create EKS Cluster in AWS using eksctl

eksctl create cluster --name demo-ekscluster --region ap-south-1 --version 1.21 --nodegroup-name linux-nodes --node-type t2.micro --nodes 2

#7:Check nodes in EKS cluster

To check the details about your node run the below command

kubectl get nodes
kubectl get namespace
kubectl describe nodes ip-192-168-14-229.ap-south-1.compute.internal
