Is it worth migrating docker apps to truenas scale community apps? (lemm.ee)

I've got forgejo configured and running as a custom docker app, but I've noticed there's a community app available now. I like using the community apps when available since I can keep them updated more easily than having to check/update image tags.

Making the switch would mean migrating from sqlite to postgres, plus some amount of file restructuring. It'll also tie my setup to truenas, which is a platform I like, but after being bit by truecharts I'm nervous about getting too attached to any platform.

Has anyone made a similar migration and can give suggestions? All I know about the postgres config is where the data is stored, so I'm not even sure how I'd connect to import anything. Is there a better way to get notified about/apply container images for custom apps instead?

I only had issues with the latest tag when dealing with the community apps. Some of them would randomly break and I'd have to roll back. Once I manually configured the docker settings using normal file mounts things were plenty stable. I think the issues were with the k8s community charts not with the underlying software. And that was fixed by just configuring it manually like however the dockerhub docs suggest.

I would still have the occasional issue where a container would freeze and a force stop wouldn't work, and spinning up a new one wouldn't work because the ports were still used. But I traced that back to a bad ssd with write timeouts. I still think truenas's k8s wrapper is buggy. Even if a container crashes hard, I shouldn't have to reboot the system to fix it. I switched to unraid and have been blissfully happy since.
