I was thinking about changing my server’s OS (currently using Ubuntu server)
Which would be the best in the case of only using docker and ZFS?
I thought that Debian would be more debloated and efficient but I need a Web UI and from what I have seen TrueNAS is very complete and is not absurdly slow, let me know your thoughts!
Would recommend dockge over portainer if you only need a web gui for docker-compose. Faster, snappier, compatible with cli, simple file structure etc.
100% this. Long long time portainer user. With multiple upgrade failures where it would not move my container setup forward i moved to dockge after it got remote system support. The difference in simplicity is night and day.
