CentOS 6.5安装使用docker
在CentOS 6.5x64上安装docker
一、安装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、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。
[root@docker ~]# docker pull centos #提示:该命令下载的是最新版的Centos:latest镜像。[root@docker ~]# docker p_w_picpaths #查看镜像 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的镜像 Pulling repository centos 8b44529354f3: Download complete 8b44529354f3: Pulling p_w_picpath (6.6) from centos Status: Downloaded newer p_w_picpath for centos:6.6
