Provides automated node provisioning and scaling for Kubernetes clusters by watching for unschedulable pods, evaluating scheduling constraints, provisioning appropriate nodes, and removing nodes when no longer needed.
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
Come discuss Karpenter in the #karpenter channel, in the Kubernetes slack or join the Karpenter working group bi-weekly calls. If you want to contribute to the Karpenter project, please refer to the Karpenter docs.
