1. 确认linux内核版本为3.8以上
$ uname -a
3.16.0-30-generic #40~14.04.1-Ubuntu
2. 检查Device Mapper
$ sudo grep device-mapper /proc/devices
3.安装docker
$ sudo apt-get -y install apt-transport-https
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
$ sudo bash -c "echo deb https://get.docker.io/ubuntu docker main >/etc/apt/sources.list.d/docker.list"
$ apt-get update
$ apt-get -y install lxc-docker
查看docker版本
$ docker -v
Docker version 1.7.1, build 786b29d
查看docker信息

4. 设置权限
由于守护进程/var/run/docker.sock的权限为docker组, 而不是主用户组, 故需要用sudo运行.如不想每次都用root用户, 可将本机用户加入到docker群组:
$ sudo gpasswd –a ${USER} docker
此时若仍出现权限问题, 请重启docker守护进程或重启计算机.
检查docker守护进程是否正在运行:
$ sudo status docker
docker start/running, process 7170
停止/开始docker守护进程:
$ sudo stop docker
$ sudo start docker
重启守护进程:
$ sudo restart docker
docker start/running, process 8015
5. 升级docker
$ sudo apt-get -u -y upgrade lxc-docker
