Docker堆栈使用GPU部署,但找不到nvidia设备

使用GPU部署docker堆栈,但找不到nvidia设备

说明:

当我使用docker-compose up启动程序时,代码运行良好!但是,当我使用docker stack deploy -c docker-compose.yml test启动该程序时,它找不到可见的nvidia设备。我的docker-compose.yml和错误日志如下所示。

我对为什么我使用相同的配置,使用docker-compose updocker stack deploy -c docker-compose.yml test的不同分配方式感到非常困惑,第一个效果不错,但第二个效果不佳。对于支持GPU的docker swarm来说,它当前是否不完美,还是我找不到其他方法?

环境配置

docker version: 18.06.0-ce
NVIDIA Docker: 1.0.1
Ubuntu: 16:04

/etc/docker/daemon.json

当然,我修改了文件/etc/docker/daemon.json,更改了运行时类型。并重新启动它。

{
  "default-runtime": "nvidia",
  "runtimes": {
    "nvidia": {
      "path": "/usr/bin/nvidia-container-runtime",
      "runtimeArgs": []
    }
  }
}
sudo systemctl daemon-reload
sudo systemctl start docker

docker-compose.yml配置文件

version: "3"

volumes:
  nvidia_driver_430.14:
    external: true

  tts-server:
    build:
      context: ./
      dockerfile: ./docker/tts_server/Dockerfile

根据问题

https://github.com/docker/compose/issues/6691

docker-compose版本3中尚未对--gpus和nvidia设备的运行时引用提供官方支持。

但是您可以安装nvidia-docker版本2并在/etc/docker/daemon.json中进行以下配置 为了使群集服务中的可用nvidia可见设备。

/etc/docker/daemon.json

{
   "default-runtime":"nvidia",
   "runtimes":{
      "nvidia":{
         "path":"nvidia-container-runtime",
         "runtimeArgs":[

         ]
      }
   }   
}

docker-compose.yaml

以以下格式在组合文件中添加环境密钥。

...
environment:
    - NVIDIA_VISIBLE_DEVICES=0
...

允许的NVIDIA_VISIBLE_DEVICES值为

NVIDIA_VISIBLE_DEVICES =全部

上述配置对我来说似乎很好。
