CentOS 6.5安装使用docker
在CentOS 6.5x64上安装docker一、安装epel源
# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# sed -i 's@#b@b@g' /etc/yum.repos.d/epel.repo
# sed -i 's@mirrorlist@#mirrorlist@g' /etc/yum.repos.d/epel.repo
#yum update -y
# yum install docker-io -y 二、获取镜像
命令格式：docker pull NAME[:TAG]
注：对于Docker镜像来说，如果不显式的指定TAG，默认会选择latest标签，即下载最新版本镜像。
从Docker Hub的centos仓库获取最新的centos镜像。
# docker pull centos #提示：该命令下载的是最新版的Centos：latest镜像。
# docker images #查看镜像
