Karpenter is a Kubernetes node autoscaler that watches for unschedulable pods, provisions right-sized nodes to meet their scheduling constraints, and removes nodes when no longer needed. It is a cloud-agnostic core with provider implementations for AWS, Azure, GCP, and many other platforms.
Use cases
- automatically scale kubernetes nodes based on pending pods
- reduce kubernetes cluster compute costs by bin-packing workloads
- provision nodes that match pod resource requests and affinities
- replace cluster autoscaler with faster node provisioning
- automatically remove underutilized kubernetes nodes
- run autoscaling across aws azure gcp kubernetes clusters
When to avoid
- you run kubernetes on-premises without a supported provider implementation
- you only need horizontal pod autoscaling rather than node autoscaling
- you want a fully managed autoscaler without operating a controller in your cluster
