We are providing one default storage class per Cluster.
Caution: This is managed by iMKE and can be overwritten at any time. Please create a separate storage class for your changes.
kubectl get storageclasses.storage.k8s.io NAME PROVISIONER AGE standard (default) kubernetes.io/cinder 268d
kubectl get storageclasses.storage.k8s.io NAME PROVISIONER AGE cinder-csi (default) cinder.csi.openstack.org 6h45m
The provisioner is version and creation time dependent.
kubernetes.io/cinderall Kubernetes Cluster prior 1.16 and created before 29.10
cinder.csi.openstack.orgall Kubernetes Cluster 1.16+ and created after 19.10
The Openstack volume types sorted by maximum possible IOPS:
- default <- used in the default class
If you need use one of the other types, you can add your own definitions.
apiVersion: storage.k8s.io/v1 kind: StorageClass metadata: name: my-high-iops-class provisioner: cinder.csi.openstack.org parameters: type: high-iops
and apply with
kubectl apply -f storage-class.yaml
nameyou should choose a unique one, as we don’t want to interfere with the default names.
provisioneruse the one of your cluster. You can always have a look in the default class to verify the right provider.
typeuse on of the official provides types from the optimist platform (as of writing low-iops and high-iops).
To use the new storage class you need to change your volumes definitions and add the new StorageClass name.
