Does docker support gpu?

Docker supports GPU, and docker can use GPU through nvidia-docker2. Configure the runtime to use nvidia in the daemon.json file. After starting the container, run nvidia-smi to see all GPUs.

Introduction to the method of mounting GPU with docker:

Using nvidia-docker2

In short, using nvidia-docker2, you can use the GPU effortlessly, just You need to configure the runtime. After starting the container using nvidia

cat /etc/docker/daemon.json
{
    "default-runtime": "nvidia",
    "runtimes": {
        "nvidia": {
            "path": "/usr/bin/nvidia-container-runtime",
            "runtimeArgs": []
        }
    },
    "exec-opts": ["native.cgroupdriver=systemd"]
}

Copy after login

, you can see all GPU cards by running nvidia-smi:

[root@localhost] docker run -it 98b41a1e975d bash
root@6db1dd28459d:/notebooks# nvidia-smi

You can add some libraries through NVIDIA_DRIVER_CAPABILITIES. Through NVIDIA_VISIBLE_DEVICES you can only use certain GPU cards

[root@localhost cuda-9.0]# docker run -it  --env NVIDIA_DRIVER_CAPABILITIES="compute,utility"  --env NVIDIA_VISIBLE_DEVICES=0,1 98b41a1e975d bash
