25. Kubernetes Namespaces Explained + Demo 🚀

Want to understand Kubernetes Namespaces the easy way? 🚀 In this video, we cover both theory and hands-on demo to help you learn what namespaces are, why they matter, and how to use them in real clusters. You’ll see how to organise resources, avoid conflicts, and manage dev, test, and prod environments step by step.

✔️ What are Kubernetes Namespaces (simple analogy)
✔️ Why we need Namespaces (organisation, isolation, collaboration)
✔️ Default Namespaces in Kubernetes (default, kube-system, kube-public, kube-node-lease)
✔️ Cluster-scoped vs Namespaced resources
✔️ Create & view namespaces using kubectl
✔️ Assign namespaces in YAML files
✔️ Switch between namespaces & manage them easily
✔️ Real-world use cases + best practices

🔥 Whether you’re a beginner or an aspiring DevOps engineer, this guide provides clear explanations and practical kubectl examples to help you master namespaces.
