Docker无法将CD复制到卷目录

Question

目标：

1. 创建docker卷
2. 转到该卷以检查我的内容

---

$ docker volume create hello_world

$ docker volume ls
DRIVER              VOLUME NAME
local               hello_world

$ docker inspect hello_world
[
    {
        "CreatedAt": "2018-11-19T05:37:03Z",
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/mnt/sda1/var/lib/docker/volumes/hello_world/_data",
        "Name": "hello_world",
        "Options": {},
        "Scope": "local"
    }
]

$ cd /mnt
bash: cd: /mnt: No such file or directory

如果我无法CD到Mountpoint，那么它将保存在哪里？

也尝试过

$ docker-machine ssh default
                        ##         .
                  ## ## ##        ==
               ## ## ## ## ##    ===
