Looks like it works.
Edit still see some performance issues. Needs more troubleshooting
Update: Registrations re-opened We encountered a bug where people could not log in, see https://github.com/LemmyNet/lemmy/issues/3422#issuecomment-1616112264 . As a workaround we opened registrations.
Thanks
First of all, I would like to thank the Lemmy.world team and the 2 admins of other servers @stanford@discuss.as200950.com and @sunaurus@lemm.ee for their help! We did some thorough troubleshooting to get this working!
The upgrade
The upgrade itself isn’t too hard. Create a backup, and then change the image names in the docker-compose.yml and restart.
But, like the first 2 tries, after a few minutes the site started getting slow until it stopped responding. Then the troubleshooting started.
The solutions
What I had noticed previously, is that the lemmy container could reach around 1500% CPU usage, above that the site got slow. Which is weird, because the server has 64 threads, so 6400% should be the max. So we tried what @sunaurus@lemm.ee had suggested before: we created extra lemmy containers to spread the load. (And extra lemmy-ui containers). And used nginx to load balance between them.
Et voilà. That seems to work.
Also, as suggested by him, we start the lemmy containers with the scheduler disabled, and have 1 extra lemmy running with the scheduler enabled, unused for other stuff.
There will be room for improvement, and probably new bugs, but we’re very happy lemmy.world is now at 0.18.1-rc. This fixes a lot of bugs.
I am still getting errors half the time I do anything while using jerboa
Website is working great though
Edit: It’s suddenly working a lot better now. Hopefully I am not jinxing myself.
You running the latest Jerboa version?
If you can no longer see your subscribed communities in the sidebar, you could be on an older version that doesn’t fully support v0.18.x
Yup, I am running 0.0.37
Ooh that’s unusual then… hopefully it’s just a temporary thing.
I’m on 0.0.35 and my Lemmyworld account works fine when I switch over to it, except this thread which lags when scrolling the comments and crashes Jerboa 😱
It’s working great now. Jerboa is really snappy now and rarely throwing errors.
I cannot even login with Jerboa

You can use Liftoff if that is still happening, also Boost for Lemmy is being developed and will probably be the main app by number of users
Liftoff having issues too. Even the most recent release from earlier today.
It worked well when I tried it, now I am getting errors xd
