What does it take to build a Kubernetes cluster on bare metal?

In this episode of KubeFM, you will learn how to plan and execute a successful setup for a bare-metal Kubernetes cluster.

You will follow Mathias' journey as he rebuilt his cluster several times and learn how to:

- Identify dependencies and priorities between components to avoid incidents in the future.
- Leverage FluxCD to have a predictable and documented setup.
- Secure the nodes from external traffic with firewalls and Cilium cluster-wide network policies.
- Use Talos to have a self-contained Kubernetes operating system.

Mathias also shared tips and advice for other engineers embarking on the same process.
