Forked Octoprint-Docker, config.yaml doesn't appear in files?

We have forked Octoprint/octoprint-docker (GitHub - OctoPrint/octoprint-docker: The dockerized snappy web interface for your 3D printer!) to make a "SimplyPrint docker" image, SimplyPrint/SimplyPi-Docker (GitHub - SimplyPrint/SimplyPi-Docker: The dockerized snappy web interface for your 3D printer!).

We have updated the config.yaml file in root/octoprint/octoprint but It dosen't seam affect the config.yaml of the instances we set up nor can I find anything else from the root folder in the instance volume.

Anyone know what we are doing wrong here, and how we can make the config.yaml file actually appear in the file system? (a config file is created on start of OctoPrint, but it doesn't contain any of our pre-set settings).

We also tried creating a few different folders, to see if the name of the folder affected anything (see here; SimplyPi-Docker/root at master · SimplyPrint/SimplyPi-Docker · GitHub), also creating a file called config2.yaml to see if the file showed up - it does not.

Any tips? :slight_smile:
