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 was having trouble earlier but now able to log in just fine on browser. Voting on posts doesn't seem to be working for me on desktop or apps. In apps I keep seeing error notices about votes not going through and desktop browser (Firefox) doesn't work but there's no notification there. Anyone else? Maybe everything needs a little time to sync up.

Browser still not working for me. The interface loads but there's no content. Also can't login on browser, after entering user and password and clicking login nothing happens.

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

[–] ruud@lemmy.world 2 points 2 years ago

Sorry hadn’t seen the message. Still interested?
