upload via docker data dir

[yewton]

There are 2 problems.

1. upload requires same version(BSD or GNU) tar command on local and remote, otherwise it raises annoying warnings ( cf. http://superuser.com/questions/318809/linux-os-x-tar-incompatibility-tarballs-created-on-os-x-give-errors-when-unt)
2. it always removes all files under remote dir, so when multiple files in the same directory are uploaded, existing files are removed one after another. This causes an error while kitchen verify with busser-serverspec.

To avoid these problems, I decided to mount a directory on container and communicate via it.

Is this reasonable approach? Any other ideas?

Thanks in advance.

Thanks for your contribution 😃

Using the data volume can not set DOCKER_HOST to remote.

But I don't have a good idea : -(

Let me think about it.

It seems the problem 2 is #16 , so just stopping rm -rf #{remote}/* should solve the problem 😰
The problem 1 is not critical, so I'll close this PR/issue.
Thanks!
