Level 1001 (9) - Kubernetes Orchestration

Beyond the realm of single containers lies a vast federation of pods, services, and deployments. Welcome to the Kubernetes Dominion—where container orchestration transforms chaos into harmony and applications scale to meet the demands of millions. Here, Expert-tier adventurers learn to command the most powerful orchestration platform in the realm.

🎯 Level Overview

Theme: Container Orchestration

XP Range: 900-1100

Tier: Expert 🔥

Kubernetes (K8s) is the industry-standard platform for container orchestration, and mastering it is essential for modern DevOps and cloud-native development. This level takes you from understanding K8s architecture to deploying and managing production workloads.

You’ll learn to work with pods, deployments, services, and ingress controllers. You’ll understand how Kubernetes manages configuration through ConfigMaps and Secrets, and how to implement persistent storage for stateful applications.
