As of qubes 4.x and docker 19+, the below method now works again. Debian-10 added with bind-dir hack works out of the box again. Dont know about other templates.
(Docker)[https://www.docker.com] a software container platform. You may have heard of it.
(Qubes-OS)[https://www.qubes-os.org] "A Reasonably Secure Operating System"
It takes a little work to get Docker running on qubes because you have to modify a templatevm. But, once you do it, you have the ease of compartmentalization qubes is famous for.
