Can't mount Windows host directory to Docker container

I'm on Windows 10 Pro with Docker Version 1.12.0-rc3-beta18 (build: 5226). I would like use Docker for PHP development on Windows machine. I tried all possible (I hope) variations of mounting host directory into Docker container:

docker run -d -P -v "C:\temp":/opt/webapp training/webapp python app.py

and

docker logs e030ba0f7807

replays as

python: can't open file 'app.py': [Errno 2] No such file or directory

What happened?

If you are using docker with docker-machine, you would need to register c:\temp first as a shared folder in VirtualBox.

See "docker with shared folder d drive"

From within a docker-machine ssh session:

sudo touch /mnt/sda1/var/lib/boot2docker/bootlocal.sh

Add to that file:

mkdir -p /mnt/temp
mount -t vboxsf -o defaults,uid=`id -u docker`,gid=`id -g docker` temp /mnt/temp

That path would then be accessible through /mnt/temp for instance.

The same applies for C:\Users, which is already a shared folder c/Users.

It is accessible with /c/Users.

With Hyper-V, see "Running Docker on Hyper-V" from Henning M Stephansen:

Hyper-V is a more isolated and restrictive environment than VMWare or VirtualBox is, so there’s no concept of shared folders.
However we can mount and access Windows shares from our Docker VM.

The first thing you need to do is to share a folder. This folder can be restricted to just your user.
If the VM has access to the network through an External Virtual Switch or an Internal Virtual Switch you should be able to mount your folder from the docker VM.

To be able to mount a windows share from Boot2Docker/Tiny Core Linux we need to install some additional module (This might be included in your image):

wget http://distro.ibiblio.org/tinycorelinux/5.x/x86/tcz/cifs-utils.tcz
tce-load -i cifs-utils.tcz

Now we can mount the shared folder using the following command

sudo mount -t cifs //HOST-IP-HERE/SharedFolderPath /path/where/we/want/it/mounted -o username=HOST_USERNAME_HERE
