# HAMi DRA Driver ## Overview DRA is a Kubernetes feature that lets you request and share resources among Pods, it provides a flexible way for requesting, configuring, and sharing specialized devices like GPUs. To learn more about DRA in general, good starting points are: [Kubernetes docs](https://kubernetes.io/docs/concepts/scheduling-eviction/dynamic-resource-allocation/), [Kubernetes blog](https://kubernetes.io/blog/2025/05/01/kubernetes-v1-33-dra-updates/). The HAMi DRA Driver brings the support of DRA for [HAMi-Core](https://github.com/Project-HAMi/HAMi-core)(the in-container GPU resource controller), it might be the first open source DRA Driver for NVIDIA GPU with [DRA Consumable Capacity](https://github.com/kubernetes/enhancements/tree/master/keps/sig-scheduling/5075-dra-consumable-capacity) feature enabled. ## Installation ### Prerequisites The list of prerequisites for running the DRA Driver for HAMi-Core is described below - NVIDIA drivers >= 440 - nvidia-docker version > 2.0 - default runtime configured as nvidia for containerd/docker/cri-o container runtime - `accept-nvidia-visible-devices-as-volume-mounts` option should be set to `true` for NVIDIA Container Runtime - Kubernetes version >= 1.34 with DRA Consumable Capacity feature enabled - glibc >= 2.17 & glibc < 2.30 - kernel version >= 3.10 Please check the [DaemonSet configuration](demo/yaml/ds.yaml) in the demo/yaml directory. We are working on a Helm Chart for this DRA Driver, it will be available in the near future. ## Demo ```yaml apiVersion: resource.k8s.io/v1 kind: ResourceClaim ... spec: devices: requests: - name: double-gpu-0-0 exactly: ... capacity: requests: cores: 30 memory: "4Gi" - name: double-gpu-0-1 exactly: ... capacity: requests: cores: 60 memory: "8Gi" ``` ![img](./imgs/hard_limit.jpg) Please refer to the [demo.md](demo/demo.md) for more information. ## Contributing Contributions require a Developer Certificate of Origin (DCO, see [CONTRIBUTING.md](https://github.com/Project-HAMi/HAMi/blob/master/CONTRIBUTING.md). ## Support Please open an issue on the GitHub project for questions and for reporting problems. Your feedback is appreciated!
