Karpenter itself can run anywhere, including on self-managed node groups, managed node groups, or AWS Fargate. This example configuration file specifies a basic cluster with one initial node. After setting up these tools, create a cluster with eksctl. It requires the installation of AWS Command Line Interface (AWS CLI), kubectl, eksctl, and Helm (the package manager for Kubernetes). I want to show a quick start using Karpenter in an Amazon EKS cluster based on Getting Started with Karpenter on AWS. Once installed in your cluster, the default Karpenter provisioner will observe incoming Kubernetes pods, which cannot be scheduled due to insufficient compute resources in the cluster and automatically launch new resources to meet their scheduling and resource requirements. Karpenter also requires permissions to provision compute resources on the provider of your choice.
KAP AND HOOD PODCAST INSTALL
To get started with Karpenter in any Kubernetes cluster, ensure there is some compute capacity available, and install it using the Helm charts provided in the public repository. If you find a bug, have a suggestion, or have something to contribute, please engage with us on GitHub. We welcome contributions to build additional cloud providers or to improve core project functionality. It is designed to work with any Kubernetes cluster running in any environment, including all major cloud providers and on-premises environments.

Karpenter is an open-source project licensed under the Apache License 2.0.
Karpenter does this by observing events within the Kubernetes cluster and then sending commands to the underlying cloud provider’s compute service, such as Amazon EC2. When Karpenter is installed in your cluster, Karpenter observes the aggregate resource requests of unscheduled pods and makes decisions to launch new nodes and terminate them to reduce scheduling latencies and infrastructure costs.
Nearly half of Kubernetes customers on AWS report that configuring cluster auto scaling using the Kubernetes Cluster Autoscaler is challenging and restrictive. Karpenter also provides just-in-time compute resources to meet your application’s needs and will soon automatically optimize a cluster’s compute resource footprint to reduce costs and improve performance.īefore Karpenter, Kubernetes users needed to dynamically adjust the compute capacity of their clusters to support applications using Amazon EC2 Auto Scaling groups and the Kubernetes Cluster Autoscaler. It helps improve your application availability and cluster efficiency by rapidly launching right-sized compute resources in response to changing application load. Karpenter is an open-source, flexible, high-performance Kubernetes cluster autoscaler built with AWS. Today we are announcing that Karpenter is ready for production.
