I've been using it on 10.3-RELEASE with some issues. For example, a CentOS-7.x image won't install httpd with an error about unpacking the cpio. Googling a bit, this turns out to be an issue with CentOS-7.x containers on Debian as well.
For very basic docker stuff, it seems to work without problems. A couple of commands didn't work, possibly "import", but I really don't remember.
DISCLAIMER. I don't use it for anything needed, at present, I've just been playing with it a little bit, trying to get more familiar with it.
