¶
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.
Check out the Docs to learn more.
