安装docker
查看是否安装docker： docker ps
未安装执行 apt install docker.io 安装docker
参考：https://www.cnblogs.com/liuwenhua/p/11527208.html
安装nvdia docker
1.删除旧docker 1.0版本
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
2.添加仓库
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | \
sudo apt-key add -
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | \
sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt-get update
（如果不行尝试如下：）
==========================================
配置存储库和密钥
distribution=$(. /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/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
添加源
curl -s -L https://nvidia.github.io/nvidia-container-runtime/experimental/$distribution/nvidia-container-runtime.list | sudo tee /etc/apt/sources.list.d/nvidia-container-runtime.list
更新源 安装nvidia-docker
sudo apt-get update
sudo apt-get install -y nvidia-docker2
重启
sudo systemctl restart docker
===============================================================
3. 安装nvidia-docker2
sudo pkill -SIGHUP dockerd
测试
docker run --runtime=nvidia --rm nvidia/cuda:9.0-base nvidia-smi
4.测试nvidia docker 是否关联gpu
使用paddle镜像，paddle镜像cuda cudnn 包含比较全比较稳定
docker images
创建容器必须要使用nvidia-docker run
nvidia-docker run -p 80:80 --name lwh -i -t registry.baidubce.com/paddlepaddle/paddle:2.1.3-gpu-cuda11.2-cudnn8 /bin/bash
nvidia-smi
检测cuda
nvcc -V
检测cudnn
dpkg -l | grep cudnn
ctrl d 退出容器
docker start -i lwh 再次重启容器
5.其他工具安装：
ping 安装 apt-get install inetutils-ping
ifconfig等网络组件安装 apt-get install net-tools
6.容器使用ubuntu18 bionic 系统 配置阿里源：
