Types

type BootstrapError 

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

func (*BootstrapError) Error 

func (e *BootstrapError) Error() string

type MockOrchestrator 

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

MockOrchestrator is a struct that implements the Orchestrator interface for use in testing frontends. Although it retains the appearance of correct functionality for this purpose, all functions are effectively nops. Note: Many of the getter methods are copied verbatim from TridentOrchestrator, since their functionality is not inherently interesting or testable.

type TridentOrchestrator 

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

func NewTridentOrchestrator 

func NewTridentOrchestrator(client persistentstore.Client) *TridentOrchestrator

NewTridentOrchestrator returns a storage orchestrator instance

func (*TridentOrchestrator) AddBackend 

func (o *TridentOrchestrator) AddBackend(configJSON string) (*storage.BackendExternal, error)

AddBackend handles creation of a new storage backend

func (*TridentOrchestrator) AddFrontend 

func (o *TridentOrchestrator) AddFrontend(f frontend.Plugin)

func (*TridentOrchestrator) AddStorageClass 

func (o *TridentOrchestrator) AddStorageClass(scConfig *storageclass.Config) (*storageclass.External, error)

func (*TridentOrchestrator) AddVolume 

func (o *TridentOrchestrator) AddVolume(volumeConfig *storage.VolumeConfig) (
	externalVol *storage.VolumeExternal, err error)

func (*TridentOrchestrator) AttachVolume 

func (o *TridentOrchestrator) AttachVolume(
	volumeName, mountpoint string, publishInfo *utils.VolumePublishInfo,
) error

AttachVolume mounts a volume to the local host. This method is currently only used by Docker, and it should be able to accomplish its task using only the data passed in; it should not need to use the storage controller API. It may be assumed that this method always runs on the host to which the volume will be attached.

func (*TridentOrchestrator) Bootstrap 

func (o *TridentOrchestrator) Bootstrap() error

func (*TridentOrchestrator) CloneVolume 

func (o *TridentOrchestrator) CloneVolume(volumeConfig *storage.VolumeConfig) (
	externalVol *storage.VolumeExternal, err error)

func (*TridentOrchestrator) DeleteStorageClass 

func (o *TridentOrchestrator) DeleteStorageClass(scName string) error

func (*TridentOrchestrator) DeleteVolume 

func (o *TridentOrchestrator) DeleteVolume(volumeName string) (err error)

DeleteVolume does the necessary set up to delete a volume during the course of normal operation, verifying that the volume is present in Trident and creating a transaction to ensure that the delete eventually completes.

func (*TridentOrchestrator) DetachVolume 

func (o *TridentOrchestrator) DetachVolume(volumeName, mountpoint string) error

DetachVolume unmounts a volume from the local host. This method is currently only used by Docker, and it should be able to accomplish its task using only the data passed in; it should not need to use the storage controller API. It may be assumed that this method always runs on the host to which the volume will be attached. It ensures the volume is already mounted, and it attempts to delete the mount point.
