Autoscale GKE cluster nodes efficiently and cost-effectively.
Note
It’s not available for use temporarily. We are diligently working on it, and it will be available shortly.
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
Karpenter observes the aggregate resource requests of unscheduled pods and makes decisions to launch and terminate nodes to minimize scheduling latencies and infrastructure cost.
We want your contributions and suggestions! One of the easiest ways to contribute is to participate in discussions on the Github Issues/Discussion, chat on IM or the bi-weekly community calls.
