Announcing graduation to General Availability (GA) - Retroactive Default StorageClass Assignment in Kubernetes v1.28!
|
||
|
|
|
||
|
|
Kubernetes SIG Storage team is thrilled to announce that the "Retroactive Default StorageClass Assignment" feature,
|
||
|
|
introduced as an alpha in Kubernetes v1.25, has now graduated to GA and is officially part of the Kubernetes v1.28 release.
|
||
|
|
This enhancement brings a significant improvement to how default
|
||
|
|
[StorageClasses](/docs/concepts/storage/storage-classes/) are assigned to PersistentVolumeClaims (PVCs).
|
||
|
|
|
||
|
|
With this feature enabled, you no longer need to create a default StorageClass first and then a PVC to assign the class.
|
||
|
|
Instead, any PVCs without a StorageClass assigned will now be retroactively updated to include the default StorageClass.
|
||
|
|
This enhancement ensures that PVCs no longer get stuck in an unbound state, and storage provisioning works seamlessly,
|
||
|
|
even when a default StorageClass is not defined at the time of PVC creation.
|
||
|
|
|
||
|
|
## What changed?
|
||
|
|
|
||
|
|
The PersistentVolume (PV) controller has been modified to automatically assign a default StorageClass to any unbound
|
||
|
|
PersistentVolumeClaim with the `storageClassName` not set. Additionally, the PersistentVolumeClaim
|
||
|
|
admission validation mechanism within
|
||
|
|
the API server has been adjusted to allow changing values from an unset state to an actual StorageClass name.
|
||
|
|
|
||
|
|
## How to use it?
|
||
|
|
|
||
|
|
As this feature has graduated to GA, there's no need to enable a feature gate anymore.
|
||
|
|
Simply make sure you are running Kubernetes v1.28 or later, and the feature will be available for use.
|
||
|
|
|
||
