Creating an EKS cluster via eksctl

To create a new Kubernetes cluster on AWS (EKS), we must first create a user with the necessary permissions.

Prerequisites

1. AWS account with appropriate permissions
2. AWS CLI installed and configured
3. eksctl installed
4. kubectl installed

Step 1: Install eksctl

<h1 id="heading-3">macOS</h1>
brew install eksctl
<h1 id="heading-4">Linux</h1> 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

Step 2: Create IAM User with Required Permissions

Create an IAM user with the following policies:

1. AmazonEKSClusterPolicy
2. AmazonEKSServicePolicy
3. AmazonEKSVPCResourceController

Step 3: Create EKS Cluster

eksctl create cluster \
--name my-cluster \ --region us-east-1 \ --nodegroup-name standard-workers \ --node-type t3.medium \ --nodes 3 \ --nodes-min 1 \ --nodes-max 4 \ --managed

Step 4: Verify Cluster Creation

eksctl get cluster
kubectl get nodes

Step 5: Configure kubectl

aws eks update-kubeconfig --name my-cluster --region us-east-1

Your EKS cluster is now ready to use!
