func (*SnapClient) CreateSnapshot

func (s *SnapClient) CreateSnapshot(ip, volName, snapName string) (*v1proto.VolumeSnapCreateResponse, error)

CreateSnapshot creates snapshot by executing gRPC call

func (*SnapClient) DestroySnapshot

func (s *SnapClient) DestroySnapshot(ip, volName, snapName string) (*v1proto.VolumeSnapDeleteResponse, error)

DestroySnapshot destroys snapshots by executing gRPC calls

type Snapshot

type Snapshot struct {
	VolumeName   string
	SnapshotName string
	Namespace    string
	SnapClient   Snapshotter
}

Snapshot holds the information required to perform snapshot related operations

func (*Snapshot) CreateSnapshot

func (s *Snapshot) CreateSnapshot(clientset clientset.Interface) (*v1proto.VolumeSnapCreateResponse, error)

CreateSnapshot creates snapshot for provided CStor Volume TODO: Think better name something like CreateSnapshotByFetchingIP

func (*Snapshot) DeleteSnapshot

func (s *Snapshot) DeleteSnapshot(clientset clientset.Interface) (*v1proto.VolumeSnapDeleteResponse, error)

DeleteSnapshot deletes snapshot for provided volume

type Snapshotter

type Snapshotter interface {
	CreateSnapshot(ip, volumeName, namesapce string) (*v1proto.VolumeSnapCreateResponse, error)
	DestroySnapshot(ip, volumeName, namesapce string) (*v1proto.VolumeSnapDeleteResponse, error)
}

Snapshotter is used to perform snapshot operations on given volume
