02-Docker-Centos 7.2 之Docker 镜像以及镜像加速

首先这是在阿里云上的一个云服务器EOS，操作系统是Linux Centos 7.2 

[root@SHUN ~]# uname -a
Linux SHUN 3.10.0-514.26.2.el7.x86_64 #1 SMP Tue Jul 4 15:04:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

按照 Aberic 大神的指导进行fabric的镜像下载

首先要清楚 Docker 的heyperledger 镜像 位置，从里面进行选择对应的docker pull 的版本

例如：

[root@SHUN ~]# docker pull hyperledger/fabric-baseos:x86_64-0.4.7
x86_64-0.4.7: Pulling from hyperledger/fabric-baseos
22dc81ace0ea: Already exists

Status: Downloaded newer image for hyperledger/fabric-baseos:x86_64-0.4.7

然后呢，最好用到一个阿里云镜像加速器使用方法

然后就好办多了，就不用苦苦的等待龟速的下载了
