Docker mounting volume for editing source code

Question

I have docker setup on my Windows system. The source code of the application is available at C:\Application\source location. I want this information to be available within the docker container so that it is easy to make code changes during development without rebuilding the image.

This is what I tried

docker run -d -P -i -t -p 8083:8080 --name html-app -v /c/Application/source:/usr/src html-app-img:vnode

The image html-app is based on Node JS

Now when I do a docker exec -it html-app /bin/bash , it doesn't show the contents of C:\Application\source there. I thought that should be available right? In the Oracle Virtual box, I've shared the folder C:\Application

Is there anything else that I need to do to get this working?

That is not enough. You need to modify your boot2docker image in order for the TinyCore Linux session to mount the shared path (only C:\Users\<yourlogin> is mounted by default as /c/Users/<yourLogin>)

See "Docker Compose Mount Window Folder"

Edit/create (as root) /mnt/sda1/var/lib/boot2docker/bootlocal.sh, (sda1 may be different for you)

Add:

mkdir -p <local_dir>
mount -t vboxsf -o defaults,uid=`id -u docker`,gid=`id -g docker` <mount_name> <local_dir>

(the mount might need umask option as well)
