Homelab
Two second-hand machines, a Raspberry Pi and a dying laptop, turned into a k3s cluster
Intro
In addition to my current homelab setup, I am refurbishing my very-old, unused laptop from my mom and a Raspberry Pi into a k3s setup.
- piloma — Raspberry Pi 5 (4C Cortex-A76, 2GB RAM, Debian 13 trixie, arm64),
with a 932G external drive hanging off USB at
/mnt/media. - alomalab — Acer Aspire ES1-131 laptop (Intel Celeron N3050, 2C/2T, 1.5GB RAM, Ubuntu 26.04) looking at the spec of this laptop, it’s better of being an e-waste.
It started as two independent Docker hosts glued together with Portainer agents and hardcoded IPs. It is now a two-node k3s cluster with piloma as the control plane and alomalab as the worker.
Both of this cluster has a sum of 4GB RAM which is less than a single tab of a chromium-based browser and it still can serve up to 2k of media to the whole house.
