I spent two hours today trying to figure out why Nextcloud couldn’t read my data directory. Docker wasn’t mounting my data directory. Moved everything into my data directory. Docker couldn’t even see the configuration file.
Turns out the Docker Snap package only has access to files under the /home directory.
Moral of the story: never trust a Snap package.
Yah, it’s been trash from the start. I tried it 2 years ago and the unpredictable weird shit it did was useless to try to troubleshoot. It was worse than trying to run Docker on Windows, if that can be believed.
Debian with the Docker convenience script is the way to run Docker.
