三.配置加速器地址：

使用自己的阿里云账号，登录阿里云dock 容器，获取自己的dock镜像地址。
[root@weblamp ~]# vim /etc/sysconfig/docker
other_args="--registry-mirror=https://amcoo07e.mirror.aliyuncs.com"

root@weblamp ~]# vim /etc/sysconfig/docker
[root@weblamp ~]# service docker restart
Stopping docker: [ OK ]
Starting docker: [ OK ]

检查配置是否成功
[root@weblamp ~]# ps -ef |grep docker
root 1363 1 0 09:59 pts/0 00:00:00 /usr/bin/docker -d --registry-
mirror=https://amcoo07e.mirror.aliyuncs.com
root 1410 1262 0 09:59 pts/0 00:00:00 grep docker

四.运行 hello-world

[root@weblamp ~]# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from hello-world
65b27d3bd74d: Pull complete
9f5834b25059: Pull complete
Digest: sha256:fb158b7ad66f4d58aa66c4455858230cd2eab4cdf29b13e5c3628a6bfc2e9f05
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
