首先创建 一个docker

root@ubuntu:~# docker run --rm=true -it -v /leader java:8 /bin/bash 

可以查看到挂载的源地址和目标地址

root@ubuntu:~# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAME
28e9ad4e8cfb        java:8              "/bin/bash"         45 seconds ago      Up 45 seconds                           conf
root@ubuntu:~# docker inspect confident_edison
    "Mounts": [
            {
                "Type": "volume",
                "Name": "84e30bc3386faa63d90bd5176fc2b41233d75e8ebdcf470768bb39c81652065c",
                "Source": "/var/lib/docker/volumes/84e30bc3386faa63d90bd5176fc2b41233d75e8ebdcf470768bb39c81652065c/_data",
                "Destination": "/leader",
                "Driver": "local",
                "Mode": "",
                "RW": true,
                "Propagation": ""
            }
        ],

多个文件挂载在本机目录

root@ubuntu:~# docker run --rm=true -it -v /storage /leader java /bin/bash

基于数据容器的单主机互联
一个容器直接和另外一个容器进行挂载
