PS：如果pull镜像后报错

Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: TLS handshake timeout

则需要进入 /etc/docker 目录下打开daemon.json 文件，如果没有这个文件，手动新建下

文件内容：

{
        "registry-mirrors":["http://docker.mirrors.ustc.edu.cn"]
}

保存退出，执行重启docker命令

$ docker run hello-world

执行结果：
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
