Permission denied when mounting sshfs volume as the working directory

[scizzorz]

I'm running into a "permission denied" error when mounting an sshfs volume that's set as the workdir for the Docker container. I've narrowed it down to the smallest possible case that I can: https://github.com/scizzorz/sshfs-bug

Running build.sh will build two images, install vieux/sshfs, create a remote volume on localhost, and then run three containers, each with the volume mounted to /data. The last container has the workdir set to /data and will not launch for me.

(if you want to test it, make sure to update the credentials/path for the volume in build.sh)
