In the absence of an upstream implementation of the DeviceRequest API introduced as part of Docker API v1.40 we roll our own using a feature label. As per my comment in the code, we fall back to the default behavior of docker cli's `--gpu` and request single device with the `gpu` capabilty. The only implementation at the moment is the NVIDIA driver; here: https://github.com/balena-os/balena-engine/blob/master/daemon/nvidia_linux.go Background on the composefile implementation: https://github.com/compose-spec/compose-spec/issues/74 https://github.com/docker/compose/issues/6691 Change-type: patch Connects-to: https://github.com/balena-os/balena-jetson/pull/75 Signed-off-by: Robert Günzler <robertg@balena.io>
