I dont know why will exec the rmmod in this .sh. Of course will active/disactive the module i think

Nothing, builded the driver from the manifacturer download. the model of the board is

Elegoo Nano board CH340 USB Driver

Hi. Could you try the following CMD:

CMD modprobe i2c-dev && modprobe ch341 && npm start

Hi @patonz, just wanted to followup quickly to see if you had any luck getting this working. Let us know if that Docker CMD above works, thanks!

Modified the run.sh and moved the “npm start” directly in the file like @CameronDiver said . Seems to work.
BTW from the original post, it changes a lot

the yml

devices: 
  - "/dev/ttyUSB0:/devttyUSB0"

dockerfile

CMD modprobe i2c-dev && modprobe usbserial && chmod +x run.sh && ./run.sh

in the run.sh file ive just commented the rmmod command. and then added the npm start after the for statement.

All sh files have to be runnable by using the chmod command as suggested before.
