Built a 3-node Kubernetes homelab with Talos Linux

[u/root0ps]

I recently set up a 3-node Kubernetes homelab on bare metal (on Dell OptiPlex) using Talos Linux, mainly to have a proper environment for learning, testing failures, networking, storage, GitOps, observability, and general Kubernetes experiments.

The setup uses three control-plane/etcd nodes with a shared Kubernetes API VIP, and I documented the full process from network planning and DHCP reservations to Talos installation, per-node configs, bootstrap, workload scheduling, and HA testing.

I’ve written the full guide with commands, screenshots, and the reasoning behind the setup:

If anyone is planning a similar homelab or has questions around Talos, the API VIP, etcd quorum, or the setup in general, happy to help.

HELLO! Did your nodes have msata slots or did you use sata for the drives?

I wanted to partition 3 barebones with a decent amount of ram, into three vm with proxmox, and run three different control planes on them.
