Map files into boot folder

[matteocarnelos]

Is it possible to map files (e.g. wpa_supplicant.conf, config.txt, dietpi.txt,...) into the boot folder of the filesystem through the Dockerfile or the docker-compose file?

I'm trying to run DietPi with this image and I would like to enable the auto setup through the dietpi.txt file.
I've tried with the following docker-compose.yml but the OS starts normally without triggering the auto setup procedure.

services:
  dockerpi:
    image: lukechilds/dockerpi:vm
    volumes:
      - ./dietpi/DietPi_RPi-ARMv6-Buster.img:/sdcard/filesystem.img
      - ./dietpi/dietpi.txt:/sdcard/boot/dietpi.txt

Issue solved by mounting the filesystem.img in the container and accessing the boot partition from there.
