原文：https://kubernetes.io/docs/tasks/administer-cluster/change-default-storage-class/

1，List the StorageClasses in your cluster:

kubectl get storageclass

2，Mark the default StorageClass as non-default:

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

3，Mark a StorageClass as default:

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

4，Verify that your chosen StorageClass is default:

kubectl get storageclass
