Node.js docker container runs when folder is located on desktop but wont in C drive

Question

I have a multi-container setup that I start with a docker-compose file. Everything works fine until I replace my setup to any folder in my C drive.

For example; When i call 'docker-compose up' here it works fine: C:\Users\me\Desktop\PrototypeEnvironment\Software\DataSearch

And it doesn't work here: C:\test

node_1     | module.js:327
node_1     |     throw err;
node_1     |     ^
node_1     |
node_1     | Error: Cannot find module '/home/app/chat/server.js'
node_1     |     at Function.Module._resolveFilename (module.js:325:15)
node_1     |     at Function.Module._load (module.js:276:25)
node_1     |     at Function.Module.runMain (module.js:441:10)
node_1     |     at startup (node.js:134:18)
node_1     |     at node.js:962:3
trunk_node_1 exited with code 1

I'm using the Docker toolbox for windows Does anyone have any idea why this happens. If you need more information please ask. Thanks in advance.

Docker-compose file:

    version: '2' 
    services:
      node:
        build: ./node_js
        command: node_modules/.bin/nodemon -L index.js
        command: node server.js
        depends_on:
          - mongo
        links:
          - mongo      
        environment:
          NODE_ENV: development  
        ports:
          - '8080:8080'
          - '3000:3000'
        volumes:
          - ./node_js:/home/app/chat
          - /home/app/chat/node_modules

      mongo:
        build: ./mongo
        ports:
          - "27017:27017"
        volumes:
          - ./mongo:/root
      nodered:
        image: jankappe/nodered
        ports:   
          - '1880:1880'

This part is tricky, the volume `/home/app/chat/node_modules`. Remove it and try again. If it works, check my answer [here](https://stackoverflow.com/questions/38425996/docker-compose-volume-on-node-modules-but-is-empty/43728476#43728476) — Robert, May 29 '17 at 13:54

Docker has a problem when you are not using C:\Users\{your_user} folder for you project location, because other folders (not from C:\Users\{your_user} folder) are some kind out of the scope of Docker. For example if I put my project in C:\my_porject then volumes from docker-compose.yml are not working. And when I put the same project somewhere inside C:\Users\{my_user}\my_porject folder (or any subfolder of user root folder) then volumes are working.

Thanks for the explanation! Is there any way to fix this, or is this just the way it is – Jan May 29 '17 at 14:00
The problem is because VirtualBox VM that is giving Linux host for Docker is sharing C:\Users. Well probably you can try to do something with this, but you must do few additional steps - look for "docker windows users folder" in web ;) – arbogastes May 29 '17 at 14:15
