Lemmy Instance on Small Private Server? (lemmy.sdf.org)

I'd like to contribute to the Lemmy community. I've been running my own private Linux servers for more than 25 years for things like email (years ago before all the spam), and as file servers, backup, etc. It's an old, not very powerful computer, running Ubuntu server, in a corner in my house. Is it worth running a Lemmy instance on such a machine? I suppose there'd also be issues of how much data is going in and out, and how that would impact my internet cable usage. Thoughts?

I'm running my instance on 2 cores, 2GB of RAM. Of course I'm the only one on there at the moment, but it's running great, and I think it might even be fine with a single core.

As other have said, if you are planning to use it for your own "user's home instance," that should be fine. I've read a few people are running their instances on Raspberry PIs, which is pretty neat. While I have one I could use, I opted to setup a new droplet in DigitalOcean instead (I also run my own servers like you). A 2 core / 2GB RAM / 50GB SSD disk droplet on DigitalOcean is about $18 (USD) a month, while a single core droplet is about $12 (USD) per month.

If you plan to run an instance for others to use, be aware the federation is going to be chatty on your home network, and could impact other devices on your network. Probably not ideal, which is why I opted for a droplet in DigitalOcean instead.

Any recommended guides? I consider myself pretty savvy with tech as a software engineer, but I’d really like some sort of docker image to just spin up on my unraid server. I’m pretty lazy playing the whole sys admin role…

I'm not familiar with unraid.

I used the documentation over on join-lemmy.org to setup my instance, on ubuntu. main docs: https://join-lemmy.org/docs/en/administration/administration.html

Here are the docker specific instructions: https://join-lemmy.org/docs/en/administration/install_docker.html

Thanks a bunch!

How much headroom do you have left on that? I'm considering starting up a public instance and would love to get an estimate for per-user workload on a federated instance.

With just me on the system, CPU is barely ever over 2 -3%. Memory usage looks fine. You know what? Let me post some graphs for the past 24 hours, which, I've pretty much been on here for 24 hours straight. Again, I'm the only user on my instance.

Super cool, thanks

It did cross my mind if I could have one of my raspberry pis run it. Actually, if it is possible I'd do on an Odroid N2+. Hmm...
