Please check the specific CSI driver's documentation for supported deployment steps for each Kubernetes release and a compatibility matrix.\n\nOnce a CSI-compatible volume driver is deployed on a Kubernetes cluster, users may use the csi volume type to attach or mount the volumes exposed by the CSI driver.\n\nA csi volume can be used in a Pod in three different ways\n\nthrough a reference to a PersistentVolumeClaim with a generic ephemeral volume with a CSI ephemeral volume if the driver supports that\n\nThe following fields are available to storage administrators to configure a CSI persistent volume\n\ndriver: A string value that specifies the name of the volume driver to use. This value must correspond to the value returned in the GetPluginInfoResponse by the CSI driver as defined in the CSI spec. It is used by Kubernetes to identify which CSI driver to call out to, and by CSI driver components to identify which PV objects belong to the CSI driver. volumeHandle: A string value that uniquely identifies the volume. This value must correspond to the value returned in the volume.id field of the CreateVolumeResponse by the CSI driver as defined in the CSI spec. The value is passed as volume_id in all calls to the CSI volume driver when referencing the volume. readOnly: An optional boolean value indicating whether the volume is to be \"ControllerPublished\" (attached) as read-only. Default is false. This value is passed to the CSI driver via the readonly field in the ControllerPublishVolumeRequest. fsType: If the PV's VolumeMode is Filesystem, then this field may be used to specify the filesystem that should be used to mount the volume. If the volume has not been formatted and formatting is supported, this value will be used to format the volume. This value is passed to the CSI driver via the VolumeCapability field of ControllerPublishVolumeRequest, NodeStageVolumeRequest, and NodePublishVolumeRequest. …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
