Building a Basic Kubernetes Cluster
In this hands-on lab, you'll build a basic Kubernetes cluster from the ground up using `kubeadm`, then deploy and expose a web application, and verify it's running correctly. You'll move beyond single-container Docker workflows and get practical, guided experience with core Kubernetes cluster administration tasks, without the complexity of multi-node or production-grade architectures.
