Docker中使用163 Hub 镜像下载加速(Centos 6)
在学习Docker的过程中，下载镜像速度特别慢，这是因为Docker Hub并没有在国内部署服务器或者CDN，再加上国内的网速慢等原因，镜像下载就十分耗时。为了克服跨洋网络延迟，能够快速高效地下载Docker镜像，最为有效的方式之一就是：使用 国内的Docker镜像源。下面就介绍一下使用163镜像源来加速的办法。添加镜像源：
vim /etc/sysconfig/docker
添加如下内容：
other_args="--registry-mirror=http://hub-mirror.c.163.com"
OPTIONS='--registry-mirror=
http://hub-mirror.c.163.com'
重启Docker服务：
# /etc/init.d/docker restart
Stopping docker:
Starting docker:
测试：
# docker search centos
