Overview

Ship stateful workloads on Kubernetes with storage that is reliable, fast, and easy to operate. Getting databases and stateful services to behave on Kubernetes is hard when storage classes, access modes, topology, and drivers do not line up. Incidents follow, from PVCs stuck in Pending to mounts that never attach. This book gives you a complete, practical blueprint. You will configure CSI the right way, bind volumes in the right place, design snapshots and restores that work under pressure, and keep upgrades safe with clear runbooks. Set up PersistentVolumes, PersistentVolumeClaims, and StorageClasses with the policies production teams need Use WaitForFirstConsumer and topology keys to prevent cross zone attachment failures Apply allowedTopologies and PV nodeAffinity for predictable placement and clean scheduler cooperation Design snapshots, clones, and restores with VolumeSnapshot and VolumeSnapshotClass, including group snapshots and quiesce strategies Hydrate environments fast with Volume Populators and AnyVolumeDataSource Grow volumes online and offline, recover from failures, and alert on risky trends Tune bound PVCs with VolumeAttributesClass and manage safe rollback with attributes classes Build durable StatefulSets with volumeClaimTemplates, stable identity, and partitioned rollouts Control disruption with Pod Disruption Budgets and safe node drain patterns Right size ephemeral storage and kubelet eviction thresholds, choose filesystems for databases, and speed startup with fsGroupPolicy and fsGroupChangePolicy Plan cloud storage performance, AWS EBS and EFS, GKE Persistent Disk and Hyperdisk and Filestore, Azure Disk and Azure Files, with IOPS and throughput targets Run on premises with Rook Ceph, CephFS and RBD, Longhorn, OpenEBS, TopoLVM, and local persistent volumes Integrate CSI snapshots into backup workflows, use Velero, and practice restore drills Move data across clusters and operate in air gapped environments Set quotas and tenancy controls for PVCs, enforce storageClassName with Kyverno or Gatekeeper, and strengthen encryption and audit trails Build storage SLOs, scrape kubelet and CSI metrics, and alert on attach, resize, and snapshot health Follow a tested upgrade runbook for CSI drivers and sidecars with canary validation Use incident playbooks for PVC Pending, node affinity conflicts, stuck finalizers, and database specific recovery This is a code heavy guide with working YAML, Bash, and JSON snippets that you can paste, adapt, and run to build real clusters and real workflows.
