@kodekloud: How To Upgrade Kubernetes Without Downtime 🔧 This is a real Kubernetes interview question: 40 nodes in production, traffic 24/7, and a version about to go end of life. The upgrade cannot cost you a single second of uptime. The trick is knowing your pods keep serving even when the control plane goes quiet, so the order you upgrade in decides whether users ever notice. You'll learn why the control plane upgrades first, why worker nodes can lag behind but never lead, and how cordon, drain, and pod disruption budgets keep your apps alive. We break it down in under 2 minutes. #Kubernetes #DevOps #KubernetesInterview #K8s #ClusterUpgrade #ZeroDowntime #CloudNative #Kubectl #SRE #PlatformEngineering #ContainerOrchestration #TechInterview #CloudComputing
