The AIO docker image put together by the NC team uses postgres. That’s the recommended way to install NC now, and having used a multitude of methods in the decade I’ve uses nextcloud, I 100% recommend the AIO image.
Is there a minimum system requirements? I have bare metal nextcloud on a raspi 4, 4 GB ram, and it’s pretty snappy.
I would consider migrating to the AIO version for more stability but IDK what toll the virtualization would take.
The virtualization shouldn’t have a negative effect, since containers are just using the host kernel so it’s not much extra overhead.
I would give it a try, it’s simple enough to set up docker on the pi, turn off your native NC install, and add the docker compose file and stand it up. Or build another SD card with a fresh raspbian install and swap it out.
