Sample codes to create different storage types in Kubernetes

Kubernetes Types of Storage.

In my previous article I talk about sample codes for kubernetes persistent storage using NFS, today I have add other storage types that can be use in Kubernetes and sample codes. You can use kubectl get storageclass to get list of storage class you already have configured.

kind: StorageClass

metadata:

  name: fast

provisioner: kubernetes.io/gce-pd

parameters:

  type: pd-ssd


##### Low speed storage classification ######

apiVersion: storage.k8s.io/v1

kind: StorageClass

metadata:

  name: slow

provisioner: kubernetes.io/gce-pd

parameters:

  type: pd-standard

 

###### Dynamic provisioning persistanct storage claim ######

apiVersion: v1

kind: PersistentVolumeClaim
