4 docker仓库
仓库是集中存放镜像的地方例如：
搭建的私有仓库地址：
192.168.89.200/ubuntu
192.168.89.200/centos
ip地址是注册服务器地址，ubuntu是仓库名
同一个注册服务器地址可以有多个不同的仓库，每个仓库又有不同的镜像
2、仓库又分为公有仓库和私有仓库
3、命令行登录docker官方维护的公有仓库（）
https://hub.docker.com/
前提是您必须提前注册有账户名和密码
root@docker-test:~# docker login
Username (tantianran): tantianran #输入用户名和密码
WARNING: login credentials saved in /root/.dockercfg. #这个文件是保存用户名和密码，密码是加密后的
Login Succeeded
root@docker-test:~#
4、登录之后，就可以非常方便的用docker search命令来搜索官方仓库中的镜像
5、例如搜索包含centos关键字的所有镜像
root@docker-test:~# docker search centos

注意：
官方镜像资源分为两类
1、单个名字命名的（例如centos）,是属于基础或根镜像，一般都是官方维护的镜像
2、命令方式为：tutum/centos 这种镜像是由dockerhub用户tutum创建并维护的
