Lemmy on a raspberry pi (self.selfhosted)

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?

[Edit] So a lot of testing around. Compiling from scratch, etc, etc...

So far i have tried

installing lemmy using rootless docker (on 0.17.3)
compiling the image 0.18 docker image as arm

rootless docker did not work well for me. lots of systemd issues and i gave up after running into a lot of issues. I tried rootless docker for security reasons. minimal permissions, etc.

When trying to compile the latest lemmy image in arm, i ran into issues with muslrust not having an arm version. It might be worth investigating rewriting the docker file from 0.17.3 to work with 0.18.0 but i haven't investigated that fully yet! I tried compiling the latest image because i wanted to be able to use the latest features

At the moment, I'm trying to set lemmy to run under bare metal. Im currently attempting to compile lemmy under arm. If that works, i'll start setting up .service files to start up lemmy and pictrs.

I don't think there should be any problems, lemmy is a fairly lightweight web application, it's compiled so no big overhead of some runtime like ruby in case of mastodon. I haven't tried it on a raspberry Pi, but on my server the load is always just around 0.1

The only bottleneck I could think of was Postgres, but I've been running postgres on raspberry pies without any problems before too.
