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 voilร . 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.

Love the update, all back up and running again :) I joined this morning after discovering this awesome Apollo replacement and was so disappointed that it was down already! Understand that the sudden surge must be huge, looking forward to seeing the data of amount of users gained by Lemmy!

Honestly praying this is the solution we all want and need!

Clearing the cache seems to have fixed the login bug.

There is another big going on where I'm seemingly logged out all the time though.

Cool beans, WefWef also seems to work now again :)

[โ€“] [email protected] 1 points 1 year ago

Congrats on figuring it out! I'm just wading into docker in a professional capacity so I admit some of it feels like magic to my traditional developer brain but glad it worked out.

[โ€“] [email protected] 1 points 1 year ago

Thank you for your hard work getting this working. It's much appreciated :)

Question @[email protected] why update to the release candidate? Just want to help testing? Or was there some readdition (ie: captcha) that had you quick on the trigger?

I'm a reddit migration and love what I saw so far! Keep it up!

[โ€“] [email protected] 1 points 1 year ago

Well done guys. Love the new update

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.

[โ€“] [email protected] 1 points 1 year ago

Congratulations on getting it up and running!

Thanks very much for your time and effort Ruud, it's much appreciated! Now, after you've put the kids to bed, grab yourself a beer and put your feet up!

[โ€“] [email protected] 1 points 1 year ago

Thank you for al the work. Do you have a need or plans for community help at all? Outside of content moderation? Not quite sure how I could help but I do software for a living.

[โ€“] [email protected] 1 points 1 year ago

Nice, hopefully this'll fix the auto refreshing new posts on PC! Thanks man ^^

Bug Iโ€™m running into -

When my mobile browser (Firefox, iOS) language is set to something other than English, not content loads and I am unable to log in.

On a somewhat related note, how are you coping with the scaling from the Reddit migration?

[โ€“] [email protected] 1 points 1 year ago

Thank you for all your hard work running this instance and for keeping us posted!

[โ€“] [email protected] 1 points 1 year ago

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.

Works with Jerboa again (yay).

Kinda makes sense that multiple containers might scale better. The actual processes within the container may have some limitations in terms of how well they thread etc.
