Kubernetes Storage Cheat Sheet for VM Administrators

on YouTube ↗30m

" summary

Compares VM and Kubernetes storage with concrete mappings: use PersistentVolumeClaim (PVC) to request space and PersistentVolume (PV) to represent actual disks, controlled by a reconciler loop; use Container Storage Interface (CSI) drivers (snapshots moving to beta) to plug vendor storage into Kubernetes. Shows operational patterns: static provisioning (precreate, e.g., 10 × 100GB volumes or pin a restored backup to a specific PV) versus dynamic provisioning, and cluster controls like namespace quotas (example: 5 PVCs ≤ 50GB) and limit ranges (e.g., require approval >100GB).
