Can't access GPIO on Python from Docker container on Raspberry Pi 5

Question

I tried to access from docker container, following docker files.

I used gpiozero (or libgpiod) because of can't use RPI.GPIO by modified GPIO access rule.

Despite what I did bind /dev/gpiomem0 , I got the error.

Traceback (most recent call last):
