关于docker:Docker-Nvidia-Driver-Nvidia-Docker-推荐安装步骤

操作系统：Ubuntu 16.04/18.04

装置 Nvidia Driver

举荐应用 graphics drivers PPA 装置 Nvidia 驱动。

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update

检测举荐的 Nvidia 显卡驱动：

ubuntu-drivers devices

装置 Nvidia 驱动（以下是 RTX2060 上的状况）：

# Ubuntu 16.04 only search 430 for CUDA < 10.2
apt-cache search nvidia
sudo apt install nvidia-430
 
# Ubuntu 18.04 could search 440 for CUDA <= 10.2
apt-cache search nvidia | grep ^nvidia-driver
sudo apt install nvidia-driver-440

驱动对应的 CUDA 版本，请见 CUDA Compatibility。

最初，sudo reboot 重启。之后，运行 nvidia-smi 输入 Nvidia 驱动信息:

$ nvidia-smi

如果装置 CUDA Toolkit，请先理解 CUDA Compatibility。装置 CUDA Toolkit 时，留神其携带的驱动版本，最好将其与驱动别离进行装置。而驱动从官网上间接找适合的版本。

装置 Docker

# update the apt package index
sudo apt-get update
# install packages to allow apt to use a repository over HTTPS
sudo apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common
 
# add Docker’s official GPG key
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
 
# set up the stable repository
sudo add-apt-repository \
  "deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu \
  $(lsb_release -cs) \
  stable"
 
# update the apt package index
sudo apt-get update
# install the latest version of Docker Engine and containerd
sudo apt-get install docker-ce docker-ce-cli containerd.io

之后，将 Docker 设为 non-root 用户可用：

sudo groupadd docker
sudo usermod -aG docker $USER

装置 Nvidia Docker

# add the package repositories
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
 
sudo apt-get update
sudo apt-get install -y nvidia-container-toolkit
sudo systemctl restart docker
