Same here. After a few years and moving it around from server to server (switched hosts a couple times), it's run flawlessly and upgrades are just one apt-get upgrade away...never had a single issue with that. We have 40+ projects and utilize container registry and CI with Kubernetes as well.
Anecdotal but I’ve gone through two major versions and a bunch of point releases at $dayjob and the worst that ever happened was a failed database migration that didn’t actually break anything.
It’s probably the easiest thing to upgrade in our entire app stack.
I ran the latest version inside docker for 6 months and used daily CI/CD across multiple environments. It's been perfectly stable and fast. Highly recommended.
