Day 27: Kubernetes Volumes | Persistent Storage | PV, PVC, StorageClass, hostPath DEMO | CKA 2025 👉 GitHub Repository: https://github.com/CloudWithVarJosh/CKA-Certification-Course-2025 👉 CKA 2025 Playlist: https://youtube.com/playlist?list=PLmPit9IIdzwRjqD-l_sZBDdPlcSfKqpAt&si=1JNRkoNa75AOJx0o 📚 Welcome to Day 27! In this lecture, we dive deep into persistent storage in Kubernetes—how Pods retain data beyond their lifecycle using PersistentVolumes (PVs), PersistentVolumeClaims (PVCs), and StorageClasses. This builds on our earlier session on ephemeral storage and sets the foundation for production-ready Kubernetes storage. 📝 What We’ll Cover: ✅ Evolution of Kubernetes Storage – From in-tree to CSI plugins ✅ hostPath Volumes – Their behavior and use cases ✅ Understanding PersistentVolumes (PVs) and PersistentVolumeClaims (PVCs) ✅ Access Modes and their practical implications ✅ Reclaim Policies and VolumeModes ✅ Dynamic Provisioning using StorageClasses ✅ Real-world Demos on PVs, PVCs, and StorageClasses ✅ AWS EBS examples with CSI driver 💡 By the end of this lecture: You’ll know how to statically and dynamically provision persistent storage in Kubernetes, when and why to use reclaim policies, how access modes affect volume sharing, and how CSI revolutionized Kubernetes storage management. 🔗 Stay Connected: 👉 LinkedIn: https://linkedin.com/in/varun-joshi-2b516752 👉 GitHub: https://github.com/CloudWithVarJosh 💬 Got questions?
