Dynamic provisioning
Dynamic provisioning is the automatic creation of persistent storage resources in response to compatible storage requests.
Kubernetes in Action, Second Edition
Dynamic provisioning is the automatic creation of persistent storage in response to a storage request rather than requiring a precreated volume.
- How it is used
- Provides persistent application storage on request, replacing pod-lifetime storage when data must survive pod replacement.
- How deep it goes
- Explains the claim-to-provisioner workflow, configuration, binding timing, and deletion lifecycle without detailing CSI driver internals.
- Examples
- Uses a 1Gi quiz-data claim, StorageClass inspection commands, and three StatefulSet claims bound to separate volumes.
- What you can do after
- Operate/configure it by requesting storage with a PVC, choosing a StorageClass, and checking claim status with kubectl.

Kubernetes for Developers
Dynamic provisioning automatically creates persistent storage resources when a workload submits a compatible storage request.
- How it is used
- Automates persistent disk creation for stateful workloads while keeping storage requests separate from provider-specific resources.
- How deep it goes
- Traces claims, StorageClasses, disks, PersistentVolumes, and binding, while deferring detailed StorageClass configuration.
- Examples
- Uses a MariaDB Pod requesting 2 GiB, kubectl output showing Bound objects, and a provider-backed CSI disk.
- What you can do after
- Apply dynamic storage through a PersistentVolumeClaim and inspect the resulting bound PersistentVolume.
