Ok, wiped RPi4 and installed the Ubuntu Server.
Installed docker and pulled the LinuxServer.io Calibre-Web image
Created the container and now have access to a new/blank calibre-web setup.
However, when I created the container, I set the config folder as /home/ubuntu/calibre, which has all my original config files. I also set my storage to the enternal USB drive, which contains ~500gb of eBooks with the metadata.db file for the calibre database.
But those locations did not 'take', so all I have is a blank CW at this point.
How do I setup my custom config files in the new container? I did use docker exec to 'edit' the container files, and tried to copy my config files into the default /config folder in the container. But that didn't work, so stuck.
FYI, total noob with docker
