Is there a guide to hosting Lemmy on an ARM64 machine? (lemmy.world)

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.

The easiest would probably be waiting for official ARM containers for 0.17.4. You could also build the containers yourself, the dockerfile should be somewhere in the Lemmy repositories.

Also, nothing's stopping you from building Lemmy from scratch and having Postgres and pictrs in container. Just make sure to forward the necessary ports.

No idea what the error is unfortunately. Are you sure you set all ENV and config variables correctly?

I might try building from scratch again and running pict-rs in a docker container.
