              安装nvidia-container-runtime.md
            
          
    docker 19.03已经正式发布了，这次发布对我来说有两大亮点。


就是docker不需要root权限来启动和运行了
就是支持GPU的增强功能，我们在docker里面想读取nvidia显卡再也不需要额外的安装nvidia-docker了

安装NVIDIA Container Runtime

cat nvidia-container-runtime-script.sh

curl -s -L https://nvidia.github.io/nvidia-container-runtime/gpgkey | \
  sudo apt-key add -
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-container-runtime/$distribution/nvidia-container-runtime.list | \
  sudo tee /etc/apt/sources.list.d/nvidia-container-runtime.list
sudo apt-get update
执行脚本

$ sh nvidia-container-runtime-script.sh
$ sudo apt-get install nvidia-container-runtime
$ which nvidia-container-runtime-hook
#/usr/bin/nvidia-container-runtime-hook
