### Container Storage Interface graduations

CSI support for Windows nodes moves to GA in the 1.22 release. In Kubernetes v1.22, Windows privileged containers are only an alpha feature. To allow using CSI storage on Windows nodes, [CSIProxy](https://github.com/kubernetes-csi/csi-proxy) enables CSI node plugins to be deployed as unprivileged pods, using the proxy to perform privileged storage operations on the node.

  General Support for vSphere 6.7 will end on October 15, 2022. vSphere 6.7 Update 3 is deprecated in Kubernetes v1.24.  Customers are recommended to upgrade vSphere (both ESXi and vCenter) to 7.0u2 or above.  vSphere CSI Driver 2.2.3 and higher supports CSI Migration.

### Promoted CSI Ephemeral Volume to Stable

* Bugfix: csi plugin supporting raw block that does not need attach mounted failed ([#79920](https://github.com/kubernetes/kubernetes/pull/79920), [@cwdsuzhou](https://github.com/cwdsuzhou))

## Prerequisites

- Helm cli with Kubernetes cluster configured.
- PV provisioner support in the underlying infrastructure. (We recommend using <https://github.com/minio/direct-csi>)
- Use Kubernetes version v1.19 and later for best experience.

## Configure MinIO Helm repo

```bash
helm repo add minio https://charts.min.io/
```

#### Storage

- When PodInfoOnMount is enabled for a CSI driver, the new csi.storage.k8s.io/ephemeral parameter in the volume context allows a driver's NodePublishVolume implementation to determine on a case-by-case basis whether the volume is ephemeral or a normal persistent volume ([#79983](https://github.com/kubernetes/kubernetes/pull/79983), [@pohly](https://github.com/pohly))

  volume type when the kubelet was started, affecting the following volume types
  when the corresponding csi driver was installed:
  - `awsElasticBlockStore` for `ebs.csi.aws.com`
  - `azureDisk` for `disk.csi.azure.com`
  - `gcePersistentDisk` for `pd.csi.storage.googleapis.com`
  - `cinder` for `cinder.csi.openstack.org`
  - `csi`

- CephRBD volume plugin ( `kubernetes.io/rbd`) was removed in this release. And its csi migration support was also removed, so the `rbd` volume type became non-functional. Alternative is to use RBD CSI driver (https://github.com/ceph/ceph-csi/) in your Kubernetes Cluster. A re-deployment of your application is required to use the new driver if you were using `kubernetes.io/rbd` volume plugin before upgrading cluster...

- Fixed an issue where a CSI migrated volume may be prematurely detached when the CSI driver is not running on the node.
