Parse Docker's --gpus flag (HostConfig.DeviceRequests) and translate it into Kubernetes device plugin resource limits (e.g. amd.com/gpu or nvidia.com/gpu) on the pod spec. Controlled by D2K_GPU_RESOURCE_NAME env var — when unset, GPU requests are silently ignored (backward compatible). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
