type CSIDriver added in v1.14.0 

type CSIDriver struct {
	metav1.TypeMeta

	// Standard object metadata.
	// metadata.Name indicates the name of the CSI driver that this object
	// refers to; it MUST be the same name returned by the CSI GetPluginName()
	// call for that driver.

}

CSIDriver captures information about a Container Storage Interface (CSI) volume driver deployed on the cluster. CSI drivers do not need to create the CSIDriver object directly. Instead they may use the cluster-driver-registrar sidecar container. When deployed with a CSI driver it automatically creates a CSIDriver object representing the driver. Kubernetes attach detach controller uses this object to determine whether attach is required. Kubelet uses this object to determine whether pod information needs to be passed on mount. CSIDriver objects are non-namespaced.

	metav1.ObjectMeta

	// spec is the specification of CSINode
	Spec CSINodeSpec
}

CSINode holds information about all CSI drivers installed on a node. CSI drivers do not need to create the CSINode object directly. As long as they use the node-driver-registrar sidecar container, the kubelet will automatically populate the CSINode object for the CSI driver as part of kubelet plugin registration. CSINode has the same name as a node. If the object is missing, it means either there are no CSI Drivers available on the node, or the Kubelet version is low enough that it doesn't create this object. CSINode has an OwnerReference that points to the corresponding node object.

	// along with values. Kubelet will expose these topology keys as labels

type CSIStorageCapacity struct {

	// Standard object's metadata. The name has no particular meaning. It must be

	// NodeTopology defines which nodes have access to the storage
	// for which capacity was reported. If not set, the storage is
	// not accessible from any node in the cluster. If empty, the
	// storage is accessible from all nodes. This field is
	// immutable.
	//
	// +optional
	NodeTopology *metav1.LabelSelector

	// The name of the StorageClass that the reported capacity applies to.

	// Capacity is the value reported by the CSI driver in its GetCapacityResponse
	// for a GetCapacityRequest with topology and parameters that match the
	// previous fields.
	//
	// The semantic is currently (CSI spec 1.2) defined as:
	// The available capacity, in bytes, of the storage that can be used

	// +optional
	Capacity *resource.Quantity

	// MaximumVolumeSize is the value reported by the CSI driver in its GetCapacityResponse
	// for a GetCapacityRequest with topology and parameters that match the

	// API is ResourceRequirements.Requests in a volume claim.
	//
	// +optional
	MaximumVolumeSize *resource.Quantity
}

CSIStorageCapacity stores the result of one CSI GetCapacity call. For a given StorageClass, this describes the available capacity in a particular topology segment. This can be used when considering where to instantiate new PersistentVolumes.

For example this can express things like: - StorageClass "standard" has "1234 GiB" available in "topology.kubernetes.io/zone=us-east1" - StorageClass "localssd" has "10 GiB" available in "kubernetes.io/hostname=knode-abc123"

The following three cases all imply that no capacity is available for a certain combination: - no object exists with suitable topology and storage class name - such an object exists, but the capacity is unset - such an object exists, but the capacity is zero

The producer of these objects can decide which approach is more suitable.

They are consumed by the kube-scheduler when a CSI driver opts into capacity-aware scheduling with CSIDriverSpec.StorageCapacity. The scheduler compares the MaximumVolumeSize against the requested size of pending volumes to filter out unsuitable nodes. If MaximumVolumeSize is unset, it falls back to a comparison against the less precise Capacity. If that is also unset, the scheduler assumes that capacity is insufficient and tries some other node.

StorageClass describes a named "class" of storage offered in a cluster. Different classes might map to quality-of-service levels, or to backup policies, or to arbitrary policies determined by the cluster administrators. Kubernetes itself is unopinionated about what classes represent. This concept is sometimes called "profiles" in other storage systems. The name of a StorageClass object is significant, and is how users can request a particular class.
