HAMi-DRA

HAMi DRA Webhook

A Kubernetes mutating webhook that converts GPU device resources to Dynamic Resource Allocation (DRA) ResourceClaims.

Overview

This webhook automatically transforms Pod specifications that request GPU resources (e.g., nvidia.com/gpu) into DRA ResourceClaims, enabling dynamic resource allocation for GPU workloads in Kubernetes.

Features

• Automatic Resource Conversion: Converts GPU resource requests to ResourceClaims
• Multi-Device Support: Supports NVIDIA GPU, MLU, Hygon DCU, Metax sGPU, Enflame VGCU, and Kunlun XPU
• Resource Cleanup: Automatically removes GPU resources from Pod specs and creates corresponding ResourceClaims
• Annotation Support: Supports device selection via Pod annotations (UUID, device type)

Quick Start

Deploy with Helm

helm install hami-dra-webhook ./chart/hami-dra-webhook

Configuration

Configure device resources in chart/hami-dra-webhook/values.yaml:

resourceName: "nvidia.com/gpu"
resourceMem: "nvidia.com/gpumem"
resourceCores: "nvidia.com/gpucores"
