29. Kubernetes DaemonSets Explained + Live Demo

Learn how Kubernetes DaemonSets work in this practical, hands-on video! I’ll explain what DaemonSets are, why they’re used, and how they automatically deploy Pods on every node in your cluster — followed by a live demo using NGINX on Minikube. Perfect for DevOps engineers, system administrators, and developers who want to master real-world Kubernetes concepts.

This tutorial covers:
✔️ Understand DaemonSets vs Deployments 🧠
✔️ One Pod per Node – explained with examples ⚙️
✔️ Real-world use cases: logging, monitoring & networking 🌐
