docker安装：
step 1: 安装必要的一些系统工具
sudo apt-get update
sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
step 2: 安装GPG证书
curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
Step 3: 写入软件源信息
sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
Step 4: 更新并安装 Docker-CE
sudo apt-get -y update
sudo apt-get -y install docker-ce
Step 5: 重启容器服务：
sudo systemctl daemon-reload
sudo systemctl restart docker
安装NVIDIA-docker
Step 1: 卸载旧版本nvidia-docker(若已安装过，可跳过)
sudo docker volume ls -q -f driver=nvidia-docker | xargs -r -I{} -n1 docker ps -q -a -f volume={} | xargs -r docker rm -f
sudo apt-get purge -y nvidia-docker
sudo apt autoremove
Setp 2: 添加apt-key
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
Step 3: 添加系统版本
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
Step 4: 更新sourcelist
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
Step 5: 安装nvidia-docker
sudo apt-get install -y nvidia-docker2
sudo pkill -SIGHUP dockerd
Step 6: 重启容器
sudo systemctl restart docker
测试demo
