Background
The Kubernetes CRI (Container Runtime Interface)
ContainerConfigAPI supports CDI (Container Device Interface) devices, and Docker Engine v25.0.0+ supports CDI devices (see Docker v25.0.0 release notes, and related PR). As an adapter between Docker and Kubelet, cri-dockerd was not passing CDI devices of the CRIContainerConfigfrom Kubelet to Docker during container creation.Changes
This PR adds support for CDI devices by:
ContainerConfigin CreateContainerDeviceRequest(Reference format for Docker DeviceRequest: https://github.com/moby/moby/pull/45134/files#diff-cd251cf1f490eeb3e90d4c15de4c983a7efad7110722baac314731de62cb0957R244).This enables full CDI device support in cri-dockerd, allowing Kubernetes workloads to use CDI devices when running on Docker via cri-dockerd.
