Rpi-gpio not available on docker container

Hi there,

In my company we are trying to work with node-red-node-pi-gpio package (not the gpiod).
When I install it locally on my linux VM it works great.
The trouble is when deploying as a container.
I tried few guides on internet with no succeed.

Tried to give privileged and root user , also access to /dev linux VM folder with volume binding.
Tried all three ways: Docker Access to Raspberry Pi GPIO Pins - Stack Overflow
Also installed all this lines on VM : node-red-node-pi-gpio (node) - Node-RED
With no success on each one of them!!

Can someone help me? I'm not getting any errors in the logs...
