Kubernetes —

Orchestrate Everything

A complete reference covering architecture, installation, core concepts, advanced features, and interview preparation — everything you need to design, deploy, and scale containerised workloads at enterprise scale.

What's inside:

The guide is structured across a fixed sidebar with active-section highlighting as you scroll, and covers:

Architecture & Installation

• Full control plane breakdown (API server, etcd, scheduler, controller manager, cloud controller manager) with a visual cluster diagram
• Worker node components (kubelet, kube-proxy, container runtime) explained in depth
• Three installation paths: Minikube (local dev), kubeadm (production, step-by-step), and a managed cloud comparison table (EKS, GKE, AKS, OpenShift)
• Complete kubectl command reference with syntax highlighting

Core Concepts

• Workloads: Pod, Deployment (with rolling update config), StatefulSet, DaemonSet, Job/CronJob — with YAML examples for each
• Services: ClusterIP, NodePort, LoadBalancer, ExternalName, Headless — all four explained with use cases
• Ingress with full TLS YAML example
• ConfigMaps, Secrets, Namespaces with security caveats
• Storage: PV, PVC, StorageClass, all four access modes in a reference table

Advanced Topics

• HPA, VPA, Cluster Autoscaler with annotated YAML
• Node affinity, taints/tolerations, pod anti-affinity, PodDisruptionBudgets
• RBAC with Role + RoleBinding YAML and least-privilege guidance
• Pod Security Standards (replacing PSP), hardened pod spec checklist
• Monitoring: liveness/readiness/startup probes, Prometheus/Grafana stack, EFK logging, distributed tracing

50+ Interview Q&A across three tabs (Beginner / Intermediate / Advanced) — all collapsible, covering reconciliation loops, rolling update internals, etcd backup/restore, zero-downtime DB migrations, CNI/kube-proxy deep dives, CrashLoopBackOff debugging, resource requests vs limits, and multi-tenant cluster design.
