= Creating a StorageClass object
|
|
|
|
When you create a StorageClass object, you set parameters that affect the
|
|
dynamic provisioning of PersistentVolumes (PVs) that belong to that storage class. +
|
|
[NOTE]
|
|
====
|
|
You cannot update a StorageClass object's parameters after you create it.
|
|

|
|
|
|
.Procedure
|
|
|
|
. Create a YAML file for defining the storage class. For example:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ touch storageclass.yaml
|
|
----
|
|
|
|
. Edit the file. For example:
|
|
+
|
|
[source,yaml]
|
|
----
|
|
apiVersion: storage.k8s.io/v1
|
|
kind: StorageClass
|
|
metadata:
|
|
name: hostpath-provisioner <1>
|
|
provisioner: kubevirt.io/hostpath-provisioner
|
|
reclaimPolicy: Delete <2>
|
|
volumeBindingMode: WaitForFirstConsumer <3>
|
|
----
|
|
<1> You can optionally rename the storage class by changing this value.
|
|
<2> The two possible `reclaimPolicy` values are `Delete` and `Retain`. If you
|
|
do not specify a value, the storage class defaults to `Delete`.
|
|
<3> The `volumeBindingMode` value determines when dynamic provisioning and volume
|
|
binding occur. Specify `WaitForFirstConsumer` to delay the binding and provisioning
|
|
of a PV until after a Pod that uses the PersistentVolumeClaim (PVC)
|
|
is created. This ensures that the PV meets the Pod's scheduling requirements.
|
|
|
|
. Create the StorageClass object:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc create -f storageclass.yaml
|
|
----
|
|
