Does anyone run their own Lemmy instance on a pi? How was the process of setting it up? Were there any pitfalls? How is performance?
Not yet, but I’m planning to. And I don’t think there will be any “pitfalls” at all other than your microsd dying in a couple of months rather than years due to it getting hammered constantly by API requests, etc.
You could plug in a USB SSD or HDD and make sure the DB and other regularly written data goes there. That would pretty much remove the problem.
I would wonder how well it would perform. The limited memory and cpu power surely would make database access not great under even moderate load.
You are right – I completely forgot about those, thanks.

Something between “usable” to “a complete nightmare” – depending of how popular the lemmy instance is. Which would scare new users away, leaving it as a “cool kids only” thing. Then again, theres the fact that the power draw is little to none, which is very important regarding most self-hosting stuff – “can’t use it if I can’t maintain it”.
Hey OP, I’m on a similar journey (except I’m using an rpi kubernetes cluster)
I don’t have advice but I do want to wish you good luck
Im looking at setting up a lemmy instance on a rpi3 with cloudflared tunnel! I’m curious to see if anyone else has done this and how it was.
Edit: I’ll give it a whirl and hopefully post an update from my new instance later!
Edit 2:
I appear to have lost my micro sd card reader! I cant write a new image hahnevermind found it!Please don’t forget to give us updates on your adventure^^
What user cap would a pi have running an instance?
Are you asking me what i plan to set the cap to? I guess just me. I cant see anyone else wanting to run off a pi from my house and there are so many other instances to join.
No, I meant what is the user limit based on the power of the raspberry pi tech specs.
Basically the limit would be the speed of the database and the drive it runs on. If you connect a SATA SSD via usb3 it shouldn’t be too bad. Can’t tell you exact figures but a few hundred users is probably ok if you don’t expect the site to be super responsive.
Thanks. Might be useful for there to be a table outling diffrent hardware configs and acceptable user loads as more people people consider creating instances.
its difficult because different users have different usage patterns.
for example, two users who never post and are never online at the same time really take no resources from each other. they are effectively “one” user.one user who posts 10gb of content a day, and is constantly posting would be equivalent to hundreds of “normal” users.
Yes, sure, didn’t want to complicate the question by adding that :)
