running workloads on Kubernetes clusters by:\n\n* **Watching** for pods that the Kubernetes scheduler has marked as unschedulable\n* **Evaluating** scheduling constraints (resource requests, nodeselectors, affinities, tolerations, and topology spread constraints) requested by the pods\n* **Provisioning** nodes that meet the requirements of the pods\n* **Removing** the nodes when the nodes are no longer needed\n\n## Karpenter Implementations\nKarpenter is a multi-cloud project with implementations by the following cloud providers:\n-
