Limit GPU usage in nvidia-docker?

I am setting up an internal Jupyterhub on a multi GPU server. Jupyter access is provided through a docker instance. I'd like to limit access for each user to no more than a single GPU. I'd appreciate any suggestion or comment. Thanks.

There are 3 options.

Docker with NVIDIA RUNTIME (version 2.0.x)

According to official documentation 

docker run --runtime=nvidia -e NVIDIA_VISIBLE_DEVICES=2,3

nvidia-docker (version 1.0.x)

based on a popular post 

nvidia-docker run .... -e CUDA_VISIBLE_DEVICES=0,1,2

(it works with tensorflow)

programmatically

import os
os.environ["CUDA_VISIBLE_DEVICES"]="0,1,2"

The problem can be solved in this way, just add the environment variable “NV_GPU” before “nvidia-docker” as follow:

 [root@bogon ~]# NV_GPU='4,5' nvidia-docker run -dit --name tf_07 tensorflow/tensorflow:latest-gpu /bin/bash
e04645c2d7ea658089435d64e72603f69859a3e7b6af64af005fb852473d6b56

You can try it with nvidia-docker-compose

version: "2"
services
  process1:
    image: nvidia/cuda
    devices:
      - /dev/nvidia0
