Installation

Install docker via:

$ sh -c "wget -qO- https://get.docker.io/gpg | apt-key add -"
$ sh -c "echo deb http://get.docker.io/ubuntu docker main\
> /etc/apt/sources.list.d/docker.list"
$ apt-get update
$ apt-get install lxc-docker
$ which docker
/usr/bin/docker

Very Beginning

Docker pull the docker.cn packages back, the speed is around 500K/

$ docker pull docker.cn/docker/ubuntu

Run into an instance:

# docker run -i -t docker.cn/docker/ubuntu /bin/bash
root@3ad7689e600a:/# ps -ef
UID        PID  PPID  C STIME TTY          TIME CMD
root         1     0  0 06:27 ?        00:00:00 /bin/bash
root        16     1  0 06:27 ?        00:00:00 ps -ef

In another terminal, show the running container:

# docker ps
