Storage Classes, Volumes, and Persistent Volumes

Introduction

This lesson covers the Storage domain (10% of the CKA, Kubernetes v1.35). The official curriculum lists: implement storage classes and dynamic volume provisioning, configure volume types, access modes and reclaim policies, and manage persistent volumes and persistent volume claims. Storage is the smallest domain by weight, but it produces fast, well-defined exam tasks ("create a PV of 1Gi on /mnt/data, a PVC that binds to it, and a Pod that mounts it") and it also appears in troubleshooting ("a Pod stays Pending because its PVC is unbound").
