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 voilΓ . 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.

Showing us the true value of horizontal instead of vertical scaling! Kubernetes when?

Thank you for your hard work.

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

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

Sorry hadn’t seen the message. Still interested?

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

Thank you so much!

thank you for upgrading! I much prefer the new URL structure of this version

Seems that sometimes the hot algorithm gets messed up :/

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

Still seeing a lot of 504s, and this is at a time where the site shouldn't be super busy

Thank you so much for doing this! The having an instance this big really made the difference for leaving reddit. I really missed jerboa and am glad to have it back as a client.

[–] [email protected] 1 points 2 years ago

So I can't login and the reset passwork button doesnt seem to do anything πŸ’€

[–] [email protected] 1 points 2 years ago

@ruud Thank you for the work you guys are doing. Without you, we wouldn't have an organized place to go after Reddit and Twitter.

Does it still sync with kbin.social?

Not gonna lie. This service is way too slow and riddled with way too many bugs. Posting comments is a huge chore as half the time there is some β€œerror”. Comments don’t load half the time.

No one is going to switch from Reddit to this service if it’s going to always be this miserable of an experience. I’d rather bang my head against the wall.
