why local bind mount not work with container on docker machine

Hello,

my container volume bind mount is not working.

I have created a docker machine named "dev". I want to share the local folder/files with the container on dev.

But I cannot see any local file.

 
$ docker-machine ls
NAME   ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER        ERRORS
dev    *        virtualbox   Running   tcp://192.168.99.100:2376           v17.10.0-ce   

[wushuzh@zion ~]$ mkdir try-mount
[wushuzh@zion ~]$ cd try-mount/
[wushuzh@zion try-mount]$ pwd
/home/wushuzh/try-mount
[wushuzh@zion try-mount]$ touch hello-container
[wushuzh@zion try-mount]$ ls -lrt
total 0
-rw-r--r-- 1 wushuzh users 0 Oct 25 11:26 hello-container
[wushuzh@zion try-mount]$ docker run -it -v $(pwd):/mnt ubuntu bash
root@8bf8ffe8bc3e:/# ls -lrt /mnt
total 0

From docker inspect, I can see that mount is set.

 
        "Mounts": [
            {
                "Type": "bind",
                "Source": "/home/wushuzh/try-mount",
                "Destination": "/mnt",
                "Mode": "",
                "RW": true,
                "Propagation": "rprivate"
            }
        ],

On the other way, I can see that vboxsf is working on VM dev, I can see the local file in VM.

Does that mean that problem is between VM and container ?

How should I continue with this investigation ?

 
$ docker-machine ssh dev
...
