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 @[email protected] and @[email protected] 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 @[email protected] 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.

obviously not critical, but it looks like there's a small sidebar bug (or feature?) that puts the pic near the instance name if it is the first thing in its description?

[–] [email protected] 3 points 2 years ago

I think that's a feature. But not 100% sure 😅
But honestly, I like the look. If it is a bug, it should become a feature 🤣

Would you mind sharing your docker-compose.yml file (sanitized, of course)? I am trying to spin up an instance on Google Cloud.

Cool

[–] ami 3 points 2 years ago

Amazing work! It seems much more performant now, everything seems to be loading faster.

[–] BitOneZero 3 points 2 years ago (1 children)

we created extra lemmy containers to spread the load. (And extra lemmy-ui containers).

Is Rust HTTP server running into thread limits? database connection pooling? All kinds of internal questions bout that solution.
