A full Kubernetes cluster you can take anywhere - securely. I built a portable Kubernetes cluster that runs over 5G, powered by Tailscale - no traditional VPNs, no open ports, no public exposure. This mini homelab rack runs Kubernetes and the Tailscale Kubernetes Operator, making it easy to self-host apps, expose private services, and connect clusters together with GitOps and zero-trust networking. And yes — Tailscale is giving away the exact mini rack from this project. Find all the giveaway details in the Tailscale Discord. Thank you for Tailscale for sponsoring this video.
