If you’re building a bare metal Kubernetes cluster with Calico and you’ve also installed Tailscale for remote access — read this before you spend hours debugging pod networking. I didn’t. I spent the hours. Here’s what I learned. The Setup Four nodes. Two ThinkPad T480s as control plane. Two ThinkCentre M720q desktops as workers. I installed Tailscale on every node so the cluster stays reachable across apartment moves — Tailscale IPs don’t change even when your home network does. ...

Project Genesis1: I Built a 4-Node Kubernetes Cluster on Bare Metal. Here’s What I Learned. At work, we provision managed Kubernetes clusters. Click a button, get a cluster. Everything abstracted. Everything handled. At home? I built every piece myself. Two control planes. Two workers. GitOps pipeline. Monitoring stack. The blog you’re reading right now? It’s running on this infrastructure.

Not the study guides. Not the practice tests. The part that comes after — when you realize the certification got you in the door, but what’s behind it is a whole different conversation. ...
