Docker on Linux - Empty mounted volumes

问题

I'm trying to get my docker setup to work on my linux machine (it works fine on OSX). I can't for the life of me get the volumes to mount properly on the linux box.

I'm on Elementary OS 0.4 Loki (64-bit)

docker version

Client:
 Version:      17.03.1-ce
 API version:  1.27

 Experimental: false

docker-machine version

docker-machine version 0.10.0, build 76ed2a6

I'm doing the following;

docker run -it -a stdout -a stderr -v /home/joel/Sites:/var/www/test --name=app pallantdigital/php7

However when I look in the container, at the /var/www folder, while it seems to pull in the folder structure ( or at least some of it ), and there are no files in the folders.

I've also tried using docker-compose like so;

image: pallantdigital/php7
  volumes:
    - /home/joel/Sites:/var/www/test

With the same result, the folder clearly gets 'mounted' but there are no files.

If I do docker inspect on the normal docker run container I get the following under 'Mounts'

"Mounts": [
        {
            "Type": "bind",
            "Source": "/home/joel/Sites",
            "Destination": "/var/www/test",
            "Mode": "",
            "RW": true,
            "Propagation": ""
        }
    ],

It's strange that 'mode' is empty.

The purpose of this was to build a development environment with a live/editable code base on the local machine which is synced across to the docker container (this is how I have it running on my mac). The php7 image is just Ubuntu with PHP7 installed.

Unfortunately most of the support questions around seem to be for Windows and Mac OSX. I've tried a few of the things people suggest, i.e. sending UID, Making sure that VirtualBox Shared Folder included the /home directory.

Any assistance would be grand, let me know if I can offer any extra information.
