Expected behavior
That I can expose a tty dev device from my mac to a linux container by running.
$ docker run --rm -it -v `pwd`:/app --device /dev/tty.usbmodem1421 node bash
Actual behavior
$ docker run --rm -it -v `pwd`:/app --device /dev/tty.usbmodem1421 node bash
docker: Error response from daemon: linux runtime spec devices: error gathering device information while adding custom device "/dev/tty.usbmodem1421": lstat /dev/tty.usbmodem1421: no such file or directory.
I can work past this with --privileged but I don't see it in /dev/
$ docker run --rm -it -v `pwd`:/app --device /dev/tty.usbmodem1421 --privileged node bash
root@5a6a7f6b8e58:/# ls /dev/tty.*
ls: cannot access /dev/tty.*: No such file or directory
According to the docs on docker run I shouldn't need --privileged.
