Types ¶
type OperationDetails ¶
type OperationDetails struct {
TaskInvocationTimestamp metav1.Time
TaskID string
OpID string
TaskStatus string
Error string
}
OperationDetails stores information about a particular operation.
type VolumeOperationRequest ¶
type VolumeOperationRequest interface {
// GetRequestDetails returns the details of the operation on the volume
// that is persisted by the VolumeOperationRequest interface.
// Returns an error if any error is encountered while attempting to
// read the previously persisted information.
GetRequestDetails(ctx context.Context, name string) (*VolumeOperationRequestDetails, error)
// StoreRequestDetails persists the details of the operation taking
// place on the volume.
// Returns an error if any error is encountered. Clients must assume
// that the attempt to persist the information failed if an error is returned.
StoreRequestDetails(ctx context.Context, instance *VolumeOperationRequestDetails) error
// DeleteRequestDetails deletes the details of the operation on the volume
// that was persisted by the VolumeOperationRequest interface.
DeleteRequestDetails(ctx context.Context, name string) error
}
VolumeOperationRequest is an interface that supports handling idempotency in CSI volume manager. This interface persists operation details invoked on CNS and returns the persisted information to callers whenever it is requested.
func InitVolumeOperationRequestInterface ¶
func InitVolumeOperationRequestInterface(ctx context.Context, cleanupInterval int, isBlockVolumeSnapshotEnabled func() bool) (VolumeOperationRequest, error)
InitVolumeOperationRequestInterface creates the CnsVolumeOperationRequest definition on the API server and returns an implementation of VolumeOperationRequest interface. Clients are unaware of the implementation details to read and persist volume operation details.
type VolumeOperationRequestDetails ¶
type VolumeOperationRequestDetails struct {
Name string
VolumeID string
SnapshotID string
Capacity int64
OperationDetails *OperationDetails
}
VolumeOperationRequestDetails stores details about a single operation on the given volume. These details are persisted by VolumeOperationRequestInterface and the persisted details will be returned by the interface on request by the caller via this structure.
func CreateVolumeOperationRequestDetails ¶
func CreateVolumeOperationRequestDetails(name, volumeID, snapshotID string, capacity int64, taskInvocationTimestamp metav1.Time, taskID, opID, taskStatus, error string) *VolumeOperationRequestDetails
CreateVolumeOperationRequestDetails returns an object of type VolumeOperationRequestDetails from the input parameters.
