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?

Not sure if you were aware of the recent (last year) drama with a major contributing group to the community apps. TrueCharts I think they were called? I had some truecharts containers and some straight truenas containers. Then TrueCharts ragequit and took down their repo. I ended up reinstalling all those apps manually because for the life of me I still couldn't get the dumb truenas versions to work. Also, I wasn't a fan of the pvc (or whatever it was called) storage containers that got used by default. Made eveverything more difficult. My advice is to use the truenas community apps as a learning tool to configure your own properly with the truenas software. I noticed the community apps would seriously take around a minute to restart, but the ones I made manually would takes seconds. Same docker image, never figured out why, maybe a k8s thing?

Yup, that's exactly why I'm iffy about tying my configuration too closely to a specific platform. Luckily my setup was still pretty small last year so the only significant thing was Jellyfin, which I just rebuilt from scratch.

Paperless takes forever to start up, it seems to be something about setting permissions on all of its files.

Do you have anything in place to track updates to your custom apps, or are you just leaving everything on the latest tag?

[–] yaroto98@lemmy.org 2 points 1 year ago

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.
