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.

A few days ago, I posted my 3-node Talos Kubernetes homelab setup here, and quite a few people reached out through DMs and comments asking for a detailed installation guide.

So I went through the entire setup again from scratch and documented the process properly, including the network setup, DHCP reservations, Talos installation, per-node configuration, Kubernetes API VIP, etcd bootstrap, workload scheduling, validation, and failure testing.

I’ve put everything together in a detailed blog with commands, screenshots, and the reasoning behind the setup.

Please check it out, and if you have any questions about the setup or run into issues while building something similar, feel free to ask.

I recently set up a small 3-node Kubernetes homelab using Dell OptiPlex Micro PCs running Talos Linux.

The main goal was to have a local cluster where I can learn, experiment, break things, and test tools without relying on cloud infrastructure every time. I’m planning to use it for Kubernetes networking, storage, observability, GitOps, security, upgrades, and general experimentation.

Small setup, but already a very useful playground.

Curious what others here are running for their Kubernetes homelabs.
