安装
docker安装的话请参考这篇文章article
Docker binds a Unix socket, but it need rootuser also.If you do not want use root, there is the best way to do it with creating dockeruser group add user into it.When the Docker daemon starts, it create a Unix socket accessible by members of the docker group.
After installing the Docker, you can verfy it with below:
yubo@debian:~/git/yuzibo.github.io/_posts$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Status: Downloaded newer image for hello-world:latest
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
