custom_apps not persistent

[ghost]

I have a docker-compose.yml file setup to bring my Nextcloud service up, and it works really well except for persistent apps.

I've mounted /var/www/html/custom_apps to an external folder as per the documentation, but it always remains empty and whenever I bring the container down and back up, all the apps are gone (they're still "enabled" in the app store, and re-enabling them brings them back with previous configuration).

Example: I enable Breeze Dark and it works correctly. Then I restart the container and it's no longer there.

docker-compose.yml for reference:

version: '3'

services:

I have the same problem - even with apps like contacts and calender.

I migrated an "normally" installed nextcloud to docker, but I also tried to delete the app folder once. How can I persist the apps?

Reenabling them after every update is not really practical...

The interesting thing is: For example calender ist not shown in the top bar - only after I navigate to apps, I can deactivate and then download and activate it - after that it is shown in the top bar until the next upgrade...
