Docker 不必多说了，也是 Demo 必备的。安排！

另外，把 docker-compose 也一并安排上。

正文

安装按照官网的说明执行即可，如果被墙可以用。安装之后，运行 sudo docker run hello-world 命令，若展示下列信息，证明安装成功。

国内镜像见 清华大学 或 中科大（同时有 Docker Hub 的镜像源）。

注意：安装之前要先移除老版本。

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
