docker学习-数据卷挂载方式

在docker学习中,学习到了数据卷这块,知道了挂载方式分为三种,分别是:匿名挂载,具名挂载,指定路径挂载

实现挂载之后会将你设定的两个路径分别绑定,任何一个下面有变动都会同步

指定路径挂载

docker run -it -v /服务器路径:/容器内路径   centos:7 /bin/bash

具体例子

[root@localhost ~]# docker run -it -v /home/test:/home/test  --name="centos04" centos:7 /bin/bash
[root@f613054c92f6 /]# cd /home/test/
[root@f613054c92f6 test]# ll
total 0
[root@f613054c92f6 test]# touch test.py
[root@f613054c92f6 test]# exit
exit
[root@localhost ~]# cd /home/t
test/ txt/
[root@localhost ~]# cd /home/test/
[root@localhost test]# ll
总用量 0
-rw-r--r--. 1 root root 0 4月  29 18:01 test.py

 

匿名挂载

docker run -it -v /容器内路径   centos:7 /bin/bash 

具体列子

[root@localhost test]# docker run -it -v /home/test  --name="centos05" centos:7 /bin/bash
[root@localhost test]# docker ps -a
