Storage Classes in Kubernetes

Question

Can somebody explain the concept of storage classes in kubernetes? What exactly is this?

Answer 1

• A StorageClass provides a way for administrators to describe the “classes” of storage they offer. 

• Different classes might map to quality-of-service levels, or to backup policies, or to arbitrary policies determined by the cluster administrators. Kubernetes itself is unopinionated about what classes represent. 

• This concept is sometimes called “profiles” in other storage systems. 

• Each StorageClass contains the fields provisioner, parameters, and reclaimPolicy, which are used when a PersistentVolume belonging to the class needs to be dynamically provisioned.
