Kubernetes Architecture Explained

What actually happens under the hood when you run `kubectl apply` or create a Deployment in Kubernetes? Most tutorials only teach you the basic CLI commands—in this deep-dive lecture, we look behind the curtain at how Kubernetes works as an asynchronous, decoupled state engine. We break down the entire Control Plane and Worker Node lifecycle step-by-step: how the API Server and etcd handle Protobuf records, how Controllers use the Informer pattern and reconciliation loops, how the Scheduler performs Predicates and Priorities, and the exact moment the Kubelet transforms metadata into physical Linux namespaces, cgroups, and network interfaces. 💬 Drop your questions in the comments below!
