Tip: Change default storageclass in Kubernetes

The below example is for OKE (Oracle Kubernetes Engine), the same concept for other Kubernetes 

Change default storageclass from oci to oci-bv:

kubectl patch storageclass oci -p '{"metadata": {"annotations":{"storageclass.beta.kubernetes.io/is-default-class":"false"}}}'

kubectl patch storageclass oci-bv -p '{"metadata": {"annotations":{"storageclass.beta.kubernetes.io/is-default-class":"true"}}}'
