func (*Snapshot) LoadSnapInfo

func (snp *Snapshot) LoadSnapInfo(infoPath string) error

LoadSnapInfo loads the snapshot info from a file. This can be useful for remote snapshots.

func (*Snapshot) SerializeSnapInfo

func (snp *Snapshot) SerializeSnapInfo() error

SerializeSnapInfo serializes the snapshot info using gob. This can be useful for remote snapshots

type SnapshotManager

type SnapshotManager struct {
	sync.Mutex
	// contains filtered or unexported fields
}

SnapshotManager manages snapshots stored on the node.

func NewSnapshotManager

func NewSnapshotManager(baseFolder string) *SnapshotManager

func (*SnapshotManager) AcquireSnapshot

func (mgr *SnapshotManager) AcquireSnapshot(revision string) (*Snapshot, error)

AcquireSnapshot returns a snapshot for the specified revision if it is available.

func (*SnapshotManager) CommitSnapshot

func (mgr *SnapshotManager) CommitSnapshot(revision string) error

CommitSnapshot finalizes the snapshot creation and makes it available for use.

func (*SnapshotManager) InitSnapshot

func (mgr *SnapshotManager) InitSnapshot(revision, image string) (*Snapshot, error)

InitSnapshot initializes a snapshot by adding its metadata to the SnapshotManager. Once the snapshot has been created, CommitSnapshot must be run to finalize the snapshot creation and make the snapshot available for use.
