The Kubernetes Machine: From kubectl apply to Running Containers

Source: https://www.podbean.com/eau/pb-599zs-... What really happens when you run kubectl apply? In Part 1 of this Kubernetes masterclass, we go far beyond basic definitions and trace how Kubernetes works as a distributed, API-driven control system. You will learn how a YAML manifest moves through kubectl, the API server, authentication, authorization, admission, etcd, controllers, the scheduler, kubelet and the container runtime before finally becoming a running Pod. This episode also explains the deeper ideas that make Kubernetes work: Desired state versus observed state Reconciliation loops spec versus status Watches and events Labels and selectors ReplicaSets and Deployments Scheduling decisions Pod lifecycle Owner references, finalizers and garbage collection Server-side apply and field ownership By the end of this episode, you will be able to mentally replay the complete journey from user intent to a healthy running workload—and understand which component is responsible at every step. Mental model: Intent → Store → Observe → Reconcile Full interview prep guides and scenario walkthroughs: DevOpsInterview.Cloud
