Storage

Persistent storage for Kubernetes workloads — Storage Classes and Persistent Volume Claims.

Storage Classes define the type and properties of persistent storage available in the cluster — the provisioner, volume type (e.g. gp3, io1), reclaim policy, and binding mode.

Persistent Volume Claims (PVCs) are requests for storage by a workload. A PVC is bound to a Persistent Volume provisioned according to the Storage Class. StatefulSets and other workloads reference PVCs to attach durable storage to their pods.

Storage Classes

Field	Description
Name	The Storage Class name
Volume Type	The EBS volume type (e.g. gp3, io1)
Reclaim Policy	What happens to the volume when the PVC is deleted: Delete or Retain
Binding Mode	Immediate or WaitForFirstConsumer
Encrypted	Whether volumes are encrypted at rest

Persistent Volume Claims

Field	Description
Name	The PVC name
Namespace	The Namespace this PVC belongs to
Storage Class	The Storage Class to provision from
Access Mode	ReadWriteOnce, ReadOnlyMany, or ReadWriteMany
Storage Size	Requested storage size (e.g. 20Gi)

Dependencies

Storage Classes and PVCs require an Environment.
