Scale ACK cluster nodes efficiently and cost-effectively.

Introduction

Karpenter is an open-source node provisioning project built for Kubernetes. Karpenter improves the efficiency and cost of running workloads on Kubernetes clusters by:

• Watching for pods that the Kubernetes scheduler has marked as unschedulable
• Evaluating scheduling constraints (resource requests, nodeselectors, affinities, tolerations, and topology spread constraints) requested by the pods
• Provisioning nodes that meet the requirements of the pods
• Removing the nodes when the nodes are no longer needed

How it works

Karpenter observes the aggregate resource requests of unscheduled pods and makes decisions to launch and terminate nodes to minimize scheduling latencies and infrastructure cost.
