安装

Docker-CE

安装过程参考官网，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 0EBFCD88

pub   4096R/0EBFCD88 2017-02-22
      Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid                  Docker Release (CE deb) <[email protected]>
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=<VERSION>


## 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

参考github

# 删除nvidia-docker1.0的容器，卸载nvidia-docker1.0
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

# 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.list
sudo apt-get update

# 安装nvidia-docker2，重新加载docker daemon的配置
sudo apt-get install -y nvidia-docker2
sudo pkill -SIGHUP dockerd

# 测试nvidia-smi命令
docker run --runtime=nvidia --rm nvidia/cuda nvidia-smi

下面是安装nvidia-docker2之后的/etc/docker/daemon.json

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

ustc mirror

在/etc/docker/daemon.json中添加新的项，使用中科大的docker镜像，多个镜像可以同时添加到列表中：

{
  "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
