Containers are ephemeral. Data must not be. This episode tackles
one of K8s's most misunderstood topics: persistent storage.
π₯ Industry Problem:
Pod crashes β restarts on a new node β local storage gone β database
data wiped. This has caused real production data loss at scale.
β Solution:
PersistentVolumes (PV) decouple storage from pods. PVCs let apps
claim storage without knowing the underlying infrastructure.
π What You'll Learn:
β Volume vs PersistentVolume vs PVC
β Access modes: ReadWriteOnce, ReadOnlyMany, ReadWriteMany
β StorageClass & Dynamic Provisioning
β Reclaim policies: Retain, Recycle, Delete
β CSI Drivers (AWS EBS, GCP PD, Azure Disk)
β Storage for databases in K8s
β Volume Snapshots
