准备

创建volume并查看（其实run的时候）

root@bogon: ~/dockerfile 00:07:40
$ docker volume create mysql_vol
root@bogon: ~/dockerfile 00:07:40
$ docker volume create wwwroot
$ docker volume ls
DRIVER              VOLUME NAME
local               mysql-vol
local               wwwroot
root@bogon: ~/dockerfile 00:08:21
$

创建自定义网络lnmp

root@bogon: ~/dockerfile 00:14:05
$ docker network create lnmp
$ docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
a8f190100335        bridge              bridge              local
1ff2dd488eff        host                host                local
3bc39c071277        lnmp                bridge              local
1c8102042db6        none                null                local
2c8ded728719        test                bridge              local

查看volume模式下wwwroot卷位置

root@bogon: ~/dockerfile 00:17:14
$ docker volume inspect wwwroot
[
    {
        "CreatedAt": "2019-03-14T23:43:08+08:00",

        "Options": null,
        "Scope": "local"
    }
]
root@bogon: ~/dockerfile 00:17:21
$

测试

root@bogon: /var/lib/docker/volumes/wwwroot/_data 00:18:22
