安装GPG key

OK
校验
panzi@ubuntu:~$ 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) <docker@docker.com>
sub 4096R/F273FCD8 2017-02-22
安装 repository
panzi@ubuntu:~$ sudo add-apt-repository
> "deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu
> $(lsb_release -cs)
> stable"
panzi@ubuntu:~$
安装 docker ce
panzi@ubuntu:~$ sudo apt-get install docker-ce
测试是否安装成功
panzi@ubuntu:~$ sudo docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

最后替换镜像
sudo sed -i "s#download.docker.com#mirrors.ustc.edu.cn/docker-ce#g" /etc/apt/sources.list
