Functions

func NewMetricsCsi

func NewMetricsCsi(volumeID string, targetPath string, driverName csiDriverName) volume.MetricsProvider

NewMetricsCsi creates a new metricsCsi with the Volume ID and path.

func ProbeVolumePlugins

func ProbeVolumePlugins() []volume.VolumePlugin

ProbeVolumePlugins returns implemented plugins

Types

type Driver

type Driver struct {
	// contains filtered or unexported fields
}

Driver is a description of a CSI Driver, defined by an enpoint and the highest CSI version supported

type DriversStore

type DriversStore struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

DriversStore holds a list of CSI Drivers

func (*DriversStore) Clear

func (s *DriversStore) Clear()

Clear deletes all entries in the store. This methiod is protected by a mutex.

func (*DriversStore) Delete

func (s *DriversStore) Delete(driverName string)

Delete lets you delete a CSI Driver by name. This method is protected by a mutex.

func (*DriversStore) Get

func (s *DriversStore) Get(driverName string) (Driver, bool)

Get lets you retrieve a CSI Driver by name. This method is protected by a mutex.

func (*DriversStore) Set

func (s *DriversStore) Set(driverName string, driver Driver)

Set lets you save a CSI Driver to the list and give it a specific name. This method is protected by a mutex.

type RegistrationHandler

type RegistrationHandler struct {
}

RegistrationHandler is the handler which is fed to the pluginwatcher API.

func (*RegistrationHandler) DeRegisterPlugin

func (h *RegistrationHandler) DeRegisterPlugin(pluginName string)

DeRegisterPlugin is called when a plugin removed its socket, signaling it is no longer available

func (*RegistrationHandler) RegisterPlugin

func (h *RegistrationHandler) RegisterPlugin(pluginName string, endpoint string, versions []string) error

RegisterPlugin is called when a plugin can be registered

func (*RegistrationHandler) ValidatePlugin

func (h *RegistrationHandler) ValidatePlugin(pluginName string, endpoint string, versions []string) error

ValidatePlugin is called by kubelet's plugin watcher upon detection of a new registration socket opened by CSI Driver registrar side car.
