☸️ Kubernetes — Zero to Hero
Master container orchestration from absolute zero. Learn to deploy, manage, debug, and scale production workloads on Kubernetes — with real-world scenarios and interview preparation.
Start Learning →🔰 Basics
Start here if you're new to Kubernetes. No prior container orchestration knowledge required.
What is Kubernetes
Understand why Kubernetes exists, how it compares to Docker, and the problems it solves.
Kubernetes Architecture
Learn every component of a cluster: control plane, nodes, etcd, kubelet, and more.
Pods
The smallest deployable unit. Understand pod lifecycle, multi-container pods, and debugging.
kubectl CLI
Master the primary tool for interacting with Kubernetes clusters.
⚙️ Intermediate
Build on the basics. Learn about deployments, networking, and configuration management.
Deployments
Declarative updates, rollouts, rollbacks, and strategies for managing application lifecycle.
Services
Expose your applications. ClusterIP, NodePort, LoadBalancer and service discovery.
ConfigMaps & Secrets
Externalize configuration. Manage environment variables, files, and sensitive data.
🚀 Advanced
Production-grade topics: traffic routing, auto-scaling, and security.
Ingress
Route external HTTP traffic to services. TLS, path-based routing, and controllers.
Scaling
Horizontal & vertical pod autoscaling, cluster autoscaler, and high-traffic handling.
Security & RBAC
Role-based access control, service accounts, network policies, and pod security.
🧪 Hands-on Labs
Apply everything you've learned with practical exercises and interview preparation.
Deploy an App
End-to-end: containerize, deploy, expose, and verify a real application on Kubernetes.
Break & Fix
Intentionally break deployments and practice fixing them under pressure.
Debugging Scenarios
CrashLoopBackOff, ImagePullBackOff, Pending pods, service issues — solve them all.
Interview Preparation
Top 20+ questions, scenario-based problems, and architecture explanations.
