Kubernetes Architecture: What Actually Happens Between `kubectl apply` and a Running Pod
But when something breaks, a Pod stuck in Pending, a Service that won't route, a Deployment that never converges, understanding that machinery is the difference between guessing and debugging. In this article, I'll map the end-to-end flow onto the actual Kubernetes architecture, so you can see not just what happens, but which component is responsible at every step. The Architecture at a Glance Kubernetes is split into two planes: Control plane: the brain.
