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.

Special thanks to the other guys for helping make this update possible. Site is snappier than ever and the UI looks fantastic.

Nice, really liking the update! Some questions about development for the fediverse: Is the code for running Lemmy written by one or person or a smome core team?

Is there any decision making process as to which features will be worked on in the next release or which bugs to prioritize?

In theory what would happen if the original developers started making changes that other people don't agree with? Would we get a fork then where servers have to choose to adopt it or not?

We're alive!!!

Thank you :)

Thanks! Seems to be working fine so far.

[–] [email protected] 5 points 2 years ago

Thanks for the update. I especially like the transparency on not only the β€œupgrade” itself but also the potential issues encountered, together with the solutions. Seems rare nowadays, or I’m just seeing less and less people doing this.

[–] [email protected] 5 points 2 years ago

New user registrations closed until tomorrow

Warning: Be careful, this might trigger this bug here: https://github.com/LemmyNet/lemmy/issues/3422#issuecomment-1616112264

It keeps logging me out, plus when I log in, alarmingly other users' profile names flash in the top right corner for a second.

[–] [email protected] 4 points 2 years ago

This looks like it’s exposed some weaknesses, and it sounds like the team has it under control.

I’m moving right now and can’t dedicate time to development, but once I’m up and running I should be able to start contributing.

Scalability is always a concern with these sites, so there’s plenty to do to improve that

Thank you!!

Is there a issue with the api? ( Because the api wrapper lemmy-js-client doesnt work on login. ) I tried it yesterday but not today yet. I will test it when i can :)

[–] [email protected] 4 points 2 years ago

Awesome work guys! The NEW front page of the internet is born.

Have you considered running your Lemmy instance on more than a single machine? If it is possible to run two lemmy containers anyway (ie, lemmy is not a singleton), why not run them on separate machines? With load balancing you could achieve a more stable experience. It might be cheaper to have many mediocre machines rather than a single powerful one too, as well as more sustainable long-term (vertical vs horizontal scaling).

The downside would be that the set-up would be less obvious than with Docker compose and you would probably need to get into k8s/k3s/nomad territory in order to orchestrate a proper fleet.
