Domoticz, Docker & GPIO

[akamming]

I am experimenting with moving my domoticxz install to docker. However on my pi it also uses the gpio pins for controlling a few lights

what is the best way to give that docker control to gpio? Adding just the gpio section of the sysfs component to the volumes secion in the compose yml file does not work, I tried

Code: Select all

 - /sys/class/gpio:/sys/class/gpio

and that didn't work

The following did the trick

Code: Select all

 - /sys:/sys

but basically that docker now has a lot of access to the pi i don't want to give it, so what is the best way to give gpio access to domoticz in a docker container without giving it too much permissions?

You most likely need to add some librarys to you docker container. Using 'customstaart.sh' you can add/install additional libraries when start the container.

From 2022.2, this functionality is present. (use google)

I am aware of that. I am already using customstart.sh Tomas the needed libertairs and also to export the GPIO pins

Problem it doesn’t work unless i expose the entire /sys fs to the docker container (apparently domotics io uses sysfs)

So my question is: hoe can i limit this from the docker container to sys as much as possible but still have gpio working within domoticz
