I currently am running the instance I am responding from on kubernetes. I published a helm chart, and others are working on them too. I feel being able to quickly deploy a kubernetes instance will help a lot of smaller instances pop up, and eventually be a good method of handling larger instances once horizontal scaling is figured out.
I tested your helm chart and it just worked :)
Is there a place I can read more about the horizontal scaling issues lemmy has?
Saved this comment. It claims that the Lemmy frontend and backend are stateless and can be scaled arbitrarily, as can the web server. The media server (pict-rs) and Postgres database are the limitations to scaling. I'm working to deploy Lemmy with external object storage to solve media storage scaling and there's probably some database experts figuring out Postgres optimization and scaling as well. None of the instances are big enough to run into serious issues with vertical scaling yet, so this won't be a problem for a while.
I’ve got my pictrs backed by an S3, so that should scale well.
I had some issues with the image server, though, and I had multiple of them running at the same time at some point, so that may have been the cause.
