[SOLVED] USB Serial device mapping into Container

[Armin@netPI]

Hello Hannes,

one thing I have to mention here about using priviledge mode on netPI. On a standard Raspberry Pi utillizing Docker in mode "priviledged" ALL /dev devices are automatically mapped. Not so with netPI. netPI includes a special version Docker mapping not ALL available host devices into the container automatically. This is because of security reasons ... else you could easily get access to the netPI SD card drive and hack netPI's security software and root system. This is what we definitively not want.

So back to your problem. Yes indeed because of my explanation above you have to map the devices manually from the beginning and start of the container. Linux maps those units to host devices called /dev/ttyUSBx if they are serial port device and x for any next device starting with 0 then 1 etc.

So you have to insert the serial devices while netPI was booting. Then you have to map /dev/ttyUSB0 and /dev/ttyUSB1 and also the bus device /dev/bus.

This should work
