dra-driver-cpu is a Kubernetes Dynamic Resource Allocation (DRA) driver that assigns exclusive CPUs to workloads through ResourceClaims. This driver provides an alternative to the CPUManager functionality implemented in the kubelet, offering additional benefits such as advanced topology selection through the rich DRA API and alignment with other DRA-managed resources (like GPUs and high-speed NICs).

Getting Started

The recommended way to install the driver is via the provided Helm chart:

helm install dra-driver-cpu oci://registry.k8s.io/dra-driver-cpu/charts/dra-driver-cpu -n kube-system

Important

Your cluster’s container runtime must support NRI and CDI — see Compatibility.
The kubelet’s CPUManager and this DRA driver are mutually incompatible, and only one can be enabled at a time on any given node — see Configuration for how to disable the CPUManager.

The Quickstart walks through installing the driver and running a pod on exclusive CPUs, with a verification step after each stage. See the Helm chart README for the full list of configuration options, and Installation for compatibility, upgrade, and uninstall details.
