Create Quick EKS Cluster

Prerequisites

• AWS CLI configured
• eksctl and kubectl installed

Quick Deployment (10 min)

Step 1: Create Cluster Configuration

Create eks-prod.yaml:

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
 
metadata:
  name: kafka-prod-cluster
  region: ap-south-1
  version: "1.33"
 
iam:
  withOIDC: true
 
availabilityZones:
  - ap-south-1a
  - ap-south-1b
  - ap-south-1c
 
managedNodeGroups:
  - name: standard-workers
    instanceType: c7i-flex.large
    # Note: change the instance type to one supported by AWS EKS, else nodes will not be provisioned
    availabilityZones:
      - ap-south-1a
      - ap-south-1b
      - ap-south-1c
    desiredCapacity: 3
    minSize: 3
    maxSize: 6
    volumeSize: 100
    volumeType: gp3
    privateNetworking: true
    ssh:
      allow: false  # Disable SSH for production
    iam:
      withAddonPolicies:
        autoScaler: true
        albIngress: true
        cloudWatch: true
        ebs: true
 
addons:
  - name: aws-ebs-csi-driver
    version: latest
    attachPolicyARNs:
      - arn:aws:iam::aws:policy/service-role/AmazonEBSCSIDriverPolicy
 
cloudWatch:
  clusterLogging:
    enableTypes:
      - api
      - audit
      - authenticator

Step 2: Deploy Cluster

# Single command creates everything
eksctl create cluster -f eks-prod.yaml
 
# Configure kubectl
aws eks update-kubeconfig --region ap-south-1 --name prod-cluster

Step 3: Verify

# Check cluster status
kubectl get nodes
kubectl get pods -A
eksctl get nodegroup --cluster prod-cluster

Production Features

• Private workers - Enhanced security
• Multi-AZ - High availability
• Auto-scaling - 3-6 nodes
• OIDC - IAM roles for pods
• Audit logging - CloudWatch enabled
• gp3 volumes - Better performance

Cleanup

eksctl delete cluster --name prod-cluster --region ap-south-1
