Well dang, I have Nextcloud installed as a snap (which has been perfectly stable for me when running on Ubuntu Server), but I was thinking of switching over to a docker installation; this thread doesn't exactly fill me with enthusiasm for that idea...
Anecdotal, but Ive had a container running Nextcloud in an LXC on Proxmox along with PiHole, Step CA, Bacula, and quite a few other services and I've had zero downtime since June 2023. Even have Tailscale rigged to use PiHole as the tailnet DNS to have adblocking on the go.
Guess that restart: always value in the Compose config is pulling it's weight lol
I ended up on the snap because I couldn't get the AIO install working properly. My snap version has been super solid. I think I'm gonna stick with it for a while.
