Starting from 24.04, I upgraded first to 24.10, then to 25.04. At the end of this process, all my apps have disappeared. Poking around in the shell shows the ix-applications folders are still there. The “pool for apps” setting had defaulted to nothing; I set it back to my pool, to no change. Trying …

Release notes are important when installing updates… It looks like you WERE running Dragonfish, which supported APP that run on Kubernetes. That functionality was dropped in Electric Eel. It’s why I didn’t upgrade beyond Dragonfish for over a year. Last summer there were multiple write ups about…

I think this is what you were going to link to? [image] WARNING: June 1st is the Apps Migration Deadline for TrueNAS 24.04 and 23.10 Announcements (Editor’s note: it’s our 1st blog to use red ink - Upgrade NOW!) On June 1st, 2025, an update to the TrueNAS Apps Catalog w…

Honestly, the fact there was no migration plan from kubernetes to docker compose is absolutely ridiculous. The TrueNAS maintainers should be absolutely ashamed of themselves, it would have taken very little effort.

Apps were able to be migrated before the changes to the App catalog. It was linked above in my post. You were able to migrate Kubernetes to Docker before that deadline.

Providing a deadline for migrating is ridiculous given that the upgrade is a minor version change and shouldn’t contain breaking changes.

This entire situation is just absolutely ridiculous and a completely self-inflicted blow to confidence in TrueNAS

You are confusing an OS upgrade with changes made with the App catalog. The changes to the App catalog required upgrading in a timely manner. Per-app IP addressing required it.

And that timeline was announced way ahead of the change, I believe almost 6 months…
