AWS EKS Karpenter Tutorial | Kubernetes Node Scaling Explained | Hands-on Demo

Описание: In this video, we deep dive into Karpenter, a next-generation Kubernetes node autoscaler for AWS EKS.

We start by understanding the limitations of Cluster Autoscaler in production environments and then explore how Karpenter solves those problems with faster scaling, dynamic EC2 instance selection, and better cost optimization.

This session includes a complete breakdown of how Karpenter works internally, including its core components such as NodePool and EC2NodeClass. We also walk through the full pod-to-node provisioning flow and finish with an end-to-end hands-on demo on AWS EKS.

Topics covered in this video:
Problems with Cluster Autoscaler
What is Karpenter and how it works
Karpenter vs Cluster Autoscaler
NodePool and EC2NodeClass explained
Kubernetes pod scheduling with Karpenter
AWS EKS node autoscaling
End-to-end Karpenter demo using Terraform
