The container has two users with permission to access GPU: openvino (UID 1000) and vaserving (UID 1001). The run scripts takes UID from host to avoid volume mounting permission issues, so if this UID > 1001, the container cannot access GPU.
Under this condition, if a request sets device to "GPU", the server will show an error as follows:
$ docker/run.sh
Found /dev/dri - enabling for GPU

Workaround is to ensure user has UID <= 1001.
