在CentOS 6.5x64上安裝docker

一、安裝epel源

[root@docker?~]#?rpm?-ivh?http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm [root@docker?~]#?sed?-i?'s@#b@b@g'?/etc/yum.repos.d/epel.repo [root@docker?~]#?sed?-i?'s@mirrorlist@#mirrorlist@g'?/etc/yum.repos.d/epel.repo [root@docker??~]#??yum?update?-y [root@docker?~]#?yum?install?docker-io?-y

二、獲取鏡像

命令格式：docker pull NAME[:TAG]

注：對于Docker鏡像來說，如果不顯式的指定TAG，默認會選擇latest標簽，即下載最新版本鏡像。

從Docker?Hub的centos倉庫獲取最新的centos鏡像。

[root@docker?~]#?docker?pull?centos????#提示：該命令下載的是最新版的Centos：latest鏡像。[root@docker?~]#?docker?p_w_picpaths????????#查看鏡像 REPOSITORY??????????TAG?????????????????IMAGE?ID????????????CREATED?????????????VIRTUAL?SIZE centos??????????????7???????????????????7322fbe74aa5????????6?days?ago??????????172.2?MB centos??????????????latest??????????????7322fbe74aa5????????6?days?ago??????????172.2?MB centos??????????????centos7?????????????7322fbe74aa5????????6?days?ago??????????172.2?MB[root@docker?~]#?docker?pull?centos:6.6????????#拉取centos6.6的鏡像 Pulling?repository?centos 8b44529354f3:?Download?complete? 8b44529354f3:?Pulling?p_w_picpath?(6.6)?from?centos?
