docker容器卷技术讲解
docker 容器中产生的数据，同步到本地，卷基础；目录的挂载，
容器的持久化，和同步操作，容器间可以数据共享。
直接使用命令挂载。
-v
docker run -it -v -p 00:00#主机目录：容器内目录
[root@localhost home]# docker ps

[root@localhost ~]# docker run -it -v /home/ceshi:/home centos /bin/bash
#[root@localhost ~]# cd /home/ 再打开一个端口查看
#[root@localhost home]# ls
#ceshi kuangshen.java shitou test.java
[root@597e67e6ca0f /]# ls
bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
[root@597e67e6ca0f /]# cd /home/
[root@597e67e6ca0f home]# ls
[root@597e67e6ca0f home]# mkdir hi
[root@597e67e6ca0f home]# ls
hi
#在另一台上查看
[root@localhost home]# ls
ceshi kuangshen.java shitou test.java
[root@localhost home]# ls ceshi/
hi
宿主机/home/ceshi，和容器中的/home是同步的双向绑定 容器停掉后也会同步的。开启容器后，查看，也能查看到与主机是同步的
