Possible to map from Mac OS host?

[anselanza]

I have been trying to get this example (and others like it) to work on a Mac OS X host.

On my setup, the Arduino shows up at /dev/cu.usbmodem144421
but running
docker run --rm -it -v "$(pwd):/src" --device=/dev/cu.usbmodem144421 strm/dev-arduino serial
(slight modification of what is in functions.sh, which assumes /dev/ttyUSB0), produces the error:

docker: Error response from daemon: linux runtime spec devices: error gathering device information while adding custom device "/dev/tty.usbmodem144421": no such file or directory.

Is device mapping fundamentally different from a Mac OS host, or am I missing something?

Hmm seems like USB device mapping on Docker for Mac might not work at all:

Unfortunelly I can't make it work on Mac OSX, but you can create a Linux virtual machine (Vmware/Virtualbox both will work) and attach the device there. I know this is not a good solution, but is the only one that I can figure out using a Mac and Arduino.

Let me know if you find a better solution to this problem, there are other people in the same situation.

Yeah, VM might be the only way to go. Hopefully Docker for Mac gets some improvements soon.
