Karpenter

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
