Types

type InTreePlugin

type InTreePlugin interface {

	// TranslateInTreeStorageClassParametersToCSI takes in-tree storage class
	// parameters and translates them to a set of parameters consumable by CSI plugin
	TranslateInTreeStorageClassParametersToCSI(scParameters map[string]string) (map[string]string, error)

	// TranslateInTreePVToCSI takes a persistent volume and will translate
	// the in-tree source to a CSI Source. The input persistent volume can be modified
	TranslateInTreePVToCSI(pv *v1.PersistentVolume) (*v1.PersistentVolume, error)

	// TranslateCSIPVToInTree takes a PV with a CSI PersistentVolume Source and will translate
	// it to a in-tree Persistent Volume Source for the in-tree volume
	// by the `Driver` field in the CSI Source. The input PV object can be modified
	TranslateCSIPVToInTree(pv *v1.PersistentVolume) (*v1.PersistentVolume, error)

	// CanSupport tests whether the plugin supports a given volume
	// specification from the API.
	CanSupport(pv *v1.PersistentVolume) bool

	// GetInTreePluginName returns the in-tree plugin name this migrates
	GetInTreePluginName() string
}

InTreePlugin handles translations between CSI and in-tree sources in a PV
