trying to spin up an instance using a raspberry pi 4

I wanted to run my own Lemmy instance but I don't have the physical space / server to run anything massive so I was trying to use a pi 4. Using the Ansible instructions I get most of the way through up to it trying to start the docker compose instance it mentions there's no Arm in the manifest file. I know it's not the strongest device but does Lemmy not support the pi outright?

  • 0.17.3 is the most recent version with an ARM64 build available.

    I don't run Lemmy on a Raspberry Pi, but I do run it on an ARM64 server platform. I couldn't upgrade to 0.17.4 and also not to 0.18.0.

    I tried to build 0.18.0 myself today and kinda succeeded, but ran into some minor issues and rolled back for now, because it's too late and I'm tired.

    I will write up some steps to get 0.18.0 running on Monday, as Sunday is my wife's birthday.

    Lemmy works on the Pi 4 (ARM) but the latest versions (0.18.0 and 0.17.4) don't provide ARM docker images for ARM machines like the Pi 4 in the official Docker repository at least (dessalines/lemmy).

    You have three options: (1) use an older version of Lemmy such as dessalines/lemmy:0.17.3-linux-arm64 or (2) pull from a different Docker repository that has the ARM builds available, or (3) build the latest version yourself using Lemmy's provided Docker files.

    If you want to pull from a different Docker repository, you can try using masquernya/lemmy:0.18.0-linux-arm64 as their build script is available on Github. I've used the same build script for my instance which also runs on an ARM machine.

    • build the latest version yourself using Lemmy's provided Docker files.

      I'm attempting to compile 0.17.4 on a Raspberry pi 3 right now. So far it's been basically frozen since 10am eastern. I'm not sure this option will work. But with that in mind I might try again with 0.17.3 if that means I don't have to compile it.

    • That other script looks interesting! I do have a few other questions. With the other script How does it handle setting a domain name, or the certbot / lets encrypt stuff I'm using cloudflare / a cloudflare tunnel so that's sort of a pain.

      I have an ansible instance of 0.17.3 up but I'm getting a black page like it hit the pi and got a response but was missing data if that makes sense. So my other question is, with ansible how do I find logs? Could it be related to nginx and certbot not communicating somehow even though the page loaded? I sorta had to modify the certbot command to use the cloudflare plugin instead of nginx if that's an issue

        It only builds the ARM Docker image and publishes it to a repository which you can use in your docker-compose.yml. It doesn't do what the Ansible playbook does where it sets up everything for you. If you want a script that sets up everything for you, check out ubergeek77's Lemmy-Easy-Deploy.

        So my other question is, with ansible how do I find logs?

        I'm not sure what ansible names the containers but for me, I can view the logs with sudo docker logs -f lemmy_lemmy_1.

        I haven't used Cloudflare Tunnels in a long time so I'm not entirely sure. I know you can locally access Lemmy via port 80 (http://localhost:80) to check if Lemmy is working and if the black page is an nginx/cloudflared issue.
