Is there a guide to hosting Lemmy on an ARM64 machine? (self.selfhosted)

I'm interested in running Lemmy on an ARM64 host, mostly just for fun and because it's possible.

I've tried a couple of things without getting it right yet:

Building from scratch on Ubuntu 20.04 This went quite well but I was unable to get pict-rs working, so there was no image hosting. I followed this guide: https://join-lemmy.org/docs/administration/from_scratch.html I had to build imagemagick to get the ARM64 binary, however pict-rs did not run. Is it correct that it's included with the lemmy-server binary or am I understanding how it works wrong?

Using Docker images I was able to get Lemmy up and running using 0.17.3 ARM64 docker images (unfortunately 0.17.4 images don't exist yet). I set up an nginx reverse proxy on the host and was able to access the instance OK, however there was no connectivity between my instance and external sites. Looking in the logs I saw timeout errors:

lemmy_1     | LemmyError { message: None, inner: Request error: error sending request for url (https://kbin.social/u/Emptiness): operation timed out
lemmy_1     | 
lemmy_1     | Caused by:
lemmy_1     |     0: error sending request for url (https://kbin.social/u/Emptiness): operation timed out

So I was wondering if anybody had a guide out there to hosting Lemmy (preferably 0.17.4) on an ARM64 host, either by building it from scratch or by using Docker images. Or any other method really.

ARM64 docker images (unfortunately 0.17.4 images don’t exist yet).

I would use the "Lemmy from Scratch", and go with using github checkout for lemmy_server code.

I'm running my instance on ARM64 on Oracle Cloud, they are giving out free ARM systems with 24GB of RAM and 200GB storage.

That does sound incredibly good for free.

Did you have any issues with pict-rs? Is it indeed included within the lemmy-server binary?

It's a little too good to be true, they have been known to shut down people without notice... I wouldn't rely on it. And the screens to use it are kind of tricky, but there are lots of instruction videos, blogs and Reddit postings about it.

I skipped that for now. I don't think ARM64 matters, Linux is Linux. I skipped it as I didn't want to take on policing images people upload, but as Lemmy improves I might change my mind.

I see no reason ARM64 should matter for Lemmy vs. x86, this is run of the mill stuff like PostgreSQL, Rust, NodeJS.

Damn, I checked out their website and it’s really tempting. I might try it a for a small hobby project that I won’t rely on long-term. Thanks for sharing!

The other catch is they only have so much capacity for free tier. I tried for a while to get one, but never had any luck.

[–] HorseFD 2 points 1 year ago (1 children)

I've just started a new instance on Oracle Cloud given how good the free tier is.

I'm maxed out on everything free: 4 CPU cores, 24 GB RAM, 200 GB storage.

Do you have any idea what the implications are of changing the block volume performance up from the default balanced to higher performance or UHP? All I can find on pricing is here: https://www.oracle.com/cloud/storage/pricing/

But it doesn't mention anything about free tier eligibility.

[–] BitOneZero 1 points 1 year ago (1 children)

No idea, I did find some Lemmy discussions on Oracle Cloud: https://lemmy.world/post/55124

I'm gonna jack it up to the highest performance and see if it eats into my first month's free credit.
