HostPath Storage using Persistent Volume
Define storage class and make it the default
| Code Block | ||||
|---|---|---|---|---|

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: hostpath-storage
annotations:
storageclass.kubernetes.io/is-default-class: "true"

Remove default status from other storage classes
> kubectl patch storageclass <STORAGE_CLASS> -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'
