Types ¶

type FsHandler ¶

type FsHandler struct {
	FsHandler common.FsHandler

	// thinPoolWatcher is the devicemapper thin pool watcher
	ThinPoolWatcher *devicemapper.ThinPoolWatcher
	// deviceID is the id of the container's fs device
	DeviceID string

	// zfsWatcher is the zfs filesystem watcher
	ZfsWatcher *zfs.ZfsWatcher
	// zfsFilesystem is the docker zfs filesystem
	ZfsFilesystem string
}

FsHandler is a composite FsHandler implementation the incorporates the common fs handler, a devicemapper ThinPoolWatcher, and a zfsWatcher

func (*FsHandler) Start ¶

func (h *FsHandler) Start()

func (*FsHandler) Stop ¶

func (h *FsHandler) Stop()

func (*FsHandler) Usage ¶

func (h *FsHandler) Usage() common.FsUsage

type StorageDriver ¶

type StorageDriver string

const (
	DevicemapperStorageDriver StorageDriver = "devicemapper"
	AufsStorageDriver         StorageDriver = "aufs"
	OverlayStorageDriver      StorageDriver = "overlay"
	Overlay2StorageDriver     StorageDriver = "overlay2"
	ZfsStorageDriver          StorageDriver = "zfs"
