AKS Storage

A brief overview of persistent storage options for AKS. This is my personal quick reference to explain how storage works, which options there are and links to further documentation.

StorageClasses - description of available classes of storage. They can have different properties like disk storage or blob storage.

kubectl get storageclasses

PersitentVolumeClaims - a users request for storage

kubectl get persistentvolumeclaims

PersistentVolumes - representation of provisioned storage in a cluster

kubectl get persistentvolumes
