As parts of the Docker story we need to be able to mount the users home directory into the VM (as docker-machine does as well). Only this way the user can then use Docker mounts to mount for example project directories into a Docker container.

docker-machine uses the vbguest additions for that, but we still need to determine whether this is possible for us due to potential licensing issues.

An alternative approach is to use sshfs and use ssh to mount the user's home directory into the VM. sshfs, however, requires a running sshd on the host. On Windows I am aware of two ways of doing that

• Cygwin - http://docs.oracle.com/cd/E24628_01/install.121/e22624/preinstall_req_cygwin_ssh.htm#EMBSC150
• Win32-OpenSSH - https://github.com/PowerShell/Win32-OpenSSH

I think the Windows ssh port would be the preferred solution, however, when testing it, the connection failed when using sshfs. I was able to simple ssh from the guest (CDK) to the host (Windows), but when using sshfs the connection would just abort. More investigation is required for using vagrant-sshfs with Win32-OpenSSH. It might just be that the Windows port is not fully functional which would leave use with the cygwin approach.

Bottom line, if we want to use the sshfs approach as an alternative for vbguest additions, we need to get sshd installed one way or the other.
