安装

Docker-CE

安装过程参考，Ubuntu中如下：

## 1. 从仓库安装$ sudo apt-get update# 使apt使用https的仓库$ sudo apt-get install \    apt-transport-https \    ca-certificates \    curl \    software-properties-common# 添加docker的官方GPG Key$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -# 验证$ sudo apt-key fingerprint 0EBFCD88pub   4096R/0EBFCD88 2017-02-22      Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88uid                  Docker Release (CE deb) 
    
     sub   4096R/F273FCD8 2017-02-22# 添加稳定版仓库$ sudo add-apt-repository \   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \   $(lsb_release -cs) \   stable"# 再次update$ sudo apt-get update# 安装docker-ce，这一步比较慢，清华的源也是在官网下载安装的$ sudo apt-get install docker-ce# hello world$ sudo docker run hello-world## 1.1 安装其他可用版本# 显示可用版本$ apt-cache madison docker-ce# 指定版本$ sudo apt-get install docker-ce=
     
      ## 2. 从deb包安装# 从https://download.docker.com/linux/ubuntu/dists/选择对应的发行版本，进入pool/stable/amd64，下载一个合适的版本$ sudo dpkg -i /path/to/package.deb
     
    

nvidia-docker

nvidia-docker用于运行基于GPU的程序，参考.

# 删除nvidia-docker1.0的容器，卸载nvidia-docker1.0docker volume ls -q -f driver=nvidia-docker | xargs -r -I{} -n1 docker ps -q -a -f volume={} | xargs -r docker rm -fsudo apt-get purge -y nvidia-docker# 添加仓库curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | \  sudo apt-key add -curl -s -L https://nvidia.github.io/nvidia-docker/ubuntu16.04/amd64/nvidia-docker.list | \  sudo tee /etc/apt/sources.list.d/nvidia-docker.listsudo apt-get update# 安装nvidia-docker2，重新加载docker daemon的配置sudo apt-get install -y nvidia-docker2sudo pkill -SIGHUP dockerd# 测试nvidia-smi命令docker run --runtime=nvidia --rm nvidia/cuda nvidia-smi

• 安装nvidia-docker2之后的/etc/docker/daemon.json

{    "runtimes": {        "nvidia": {            "path": "/usr/bin/nvidia-container-runtime",            "runtimeArgs": []        }    }}

免sudo运行docker命令

• 创建docker组
  $ sudo groupadd docker
• 添加当前用户到该docker组
  $ sudo usermod -aG docker $USER
• 注销后重新登录
• 运行hello-world程序进行测试。如果提示以下错误：

WARNING: Error loading config file: /home/user/.docker/config.json -stat /home/user/.docker/config.json: permission denied

原因是在当前用户加入docker组之前以sudo权限配置了docker，配置目录～/.docker/的权限是sudo的。解决方法有两个：

• 删除～/.docker/，重新配置
• 用下面的命令更改权限

$ sudo chown "$USER":"$USER" /home/"$USER"/.docker -R$ sudo chmod g+rwx "/home/$USER/.docker" -R

ustc mirrors

在/etc/docker/daemon.json中添加新的项，使用中科大的docker镜像：

{  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn/"]}

然后重启docker服务

sudo service docker restart

service failed

Fixing the Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details. problem, for me this worked:

1. sudo rm -rf /var/lib/docker
2. create daemon.json in /etc/docker/
3. put this in it:
   {
   "exec-root": "/path/to/docker/run",
   "storage-driver": "overlay",
   "graph": "/path/to/docker/lib"
   }
4. systemctl start docker
5. docker run --rm hello-world
