Persistent volume claim

As explained in Effective Platform Engineering

A persistent volume claim is a Kubernetes resource that requests persistent storage with specified capacity and access requirements.

How Effective Platform Engineering covers it

How deep it goes

Demonstrates manifests and executable checks but stops short of explaining claim-binding internals.

Examples

Uses EBS ReadWriteOnce and EFS ReadWriteMany claims with mounted pods, timestamp files, Bats checks, and capacity expansion.

What it assumes

Assumes Kubernetes, EKS, pods, StorageClasses, CSI drivers, and kubectl while illustrating claim testing through fixtures.

What you can do after

Diagnose storage integration by verifying binding, pod health, write access, shared writes, and claim expansion.

How it connects

Connects PersistentVolume, StorageClass, Pod, access modes, dynamic provisioning, volume expansion, node affinity, and tolerations.
