。。。这是为何？ 我按照下面的方法进入。。。
[root@docker_01 ~]# docker ps -aCONTAINER IDIMAGE COMMAND CREATED STATUS PORTS NAMES98a498cff145hub.c.163.com/public/centos:6.7-tools '/usr/bin/supervisord' 3 minutes ago Up 3 minutes22/tcp ceshi_2[root@docker_01 ~]# sh d.sh 98a498cff1453396[root@98a498cff145 ~]# lsanaconda-ks.cfg d.sh new.file[root@98a498cff145 ~]# exit logout[root@docker_01 ~]# lsanaconda-ks.cfg d.sh new.file

为什么物理系统和容器里面的文件都是一样的？。。。。
问题解答
回答1：你REPOSITORY下没有叫centos的镜像。而是叫hub.c.163.com/public/centos 。所以他会去拉去centos 最新的版本
docker run --name ceshi -it hub.c.163.com/public/centos
