What specs for a self-hosted Lemmy instance? (aussie.zone)

Hi all, a shout-out for assistance. I’m considering hosting a Lemmy instance (assuming I can pass the wife test on costs) and I’m looking for some guidance on specs.

Can anyone who’s currently hosting an instance (or who knows the inner workings of one) please reply with:

  • specs on the hardware / VPS that’s hosting your instance
  • how many users / posts that’s supporting
  • what the system load looks like with the above
  • if locally hosting, the type of bandwidth requirements you’re seeing

I previously posted this in the wrong community, and one of the responses asked how many users I'm expecting. To preemptively answer - I don't know. I'm just trying to get an idea of relative sizing.

Thank you!!

Myself i'm running a instance for two people in a pretty small lxc container on my home server- 1vCore, 512MB of ram and 8GB storage. Currently it utilize around 5% of CPU, ~250MB of ram (+260MB of swap), and ~2GB of storage (nearly 50/50 picts/postgres), in terms of network traffic i see average of 20kb/s, depends how many communities are you subscribed for.

My homeserver is running on i3-4150, 16GB ram and a couple of ssds, using Proxmox VE as hypervisor

edit: typo

How are you routing it to the internet?

[-] moira@femboys.bar 2 points 1 year ago

I'm using hestiacp to host some websites anyway, so i just added a new nginx template to create reverse proxy to lemmy+lemmy_ui containers

I really want to figure out if it's possible to stick it behind cloudflare or something. I would rather not expose any IP address directly to the internet. I'm leaning on just setting up a reverse proxy on a cheap cloud instance back to my home.

My instance is actually behind cloudflare and it works fine, but remember that it would be possible to "expose" ip of your server due to federation, as your server will talk to other server (directly, that traffic won't go over cloudflare), so if you are paranoid about that, i would recommend setting up a wireguard tunnel to cloud instance, and forwarding the traffic that way, or just setup the lemmy on that instance

Thanks that's kind of what I was thinking. Have you used cloudflared before?

[-] moira@femboys.bar 1 points 1 year ago

No, i didn't, but i think it should also work over cloudflared
