QUESTION
I am trying to use docker for development by mounting a folder from the container to host, as the standard approach of host-to-container doesn't work well for a certain project I am working upon.
Currently, I do that using bindfs
(which also maps the user permission) as suggested in this issue:

If your main intend is to allow shipping your run-time environment as a single bundled container image but allowing your users to access and modify application files then using an ordinary bind-volume and copying the files on startup would by the easiest way in my opinion, i.e.
QUESTION
I've been experimenting with running apps within a chroot-ed directory.
Many apps and binaries require access to items within /dev, such as /dev/null and /dev/random to work.
Is there a way to recreate or bind mount the /dev filesystem within a directory to this end?
I have tried the following without success:
