there are two kinds of provisioner in kubernetes storageclass one is：
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: hdd1
provisioner: kubernetes.io/cinder
parameters:
type: HDD1 # change for your cloud volume type
availability: nova
and one is :
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
name: cinder-standard-iops
provisioner: openstack.org/standalone-cinder
parameters:
type: standard-iops
I'm wondering what's the difference between them,Thanks!
provisioner: kubernetes.io/cinder default driver is described in official documentation.
provisioner: openstack.org/standalone-cinder : a beta feature which was created for use with external Cinder storage.
Here you can find the main discussion about adding additional provisioner toCinder-standalone.
The builtin kubernetes cinder support expects that nodes are deployed on nova instances. In order to use cinder as a standalone storage service I'd like to add an external provisioner. This provisioner creates volumes in cinder and retrieves connection information. It then translates this connection information into a native k8s PV (ie. iscsi or rbd are already implemented).
