func MakeSnapshotName ¶
func MakeSnapshotName(snapshot *crdv1.VolumeSnapshot) string
MakeSnapshotName makes a full name for a snapshot that includes the namespace and the short name
Types ¶
type ActualStateOfWorld ¶
type ActualStateOfWorld interface {
// Adds snapshot to the list of snapshots. No-op if the snapshot
// is already in the list.
AddSnapshot(*crdv1.VolumeSnapshot) error
// Deletes the snapshot from the list of known snapshots. No-op if the snapshot
// does not exist.
DeleteSnapshot(snapshotName string) error
// Return a copy of the known snapshots
GetSnapshots() map[string]*crdv1.VolumeSnapshot
// Get snapshot by its name
GetSnapshot(snapshotName string) *crdv1.VolumeSnapshot
// Check whether the specified snapshot exists
SnapshotExists(snapshotName string) bool
}
ActualStateOfWorld defines a set of thread-safe operations supported on the snapshot controller's actual state of the world cache. This cache contains snapshots the snapshot controller believes are successfully created.
func NewActualStateOfWorld ¶
func NewActualStateOfWorld() ActualStateOfWorld
NewActualStateOfWorld returns a new instance of ActualStateOfWorld.
type DesiredStateOfWorld ¶
type DesiredStateOfWorld interface {
// Adds snapshot to the list of snapshots. No-op if the snapshot
// is already in the list.
AddSnapshot(*crdv1.VolumeSnapshot) error
// Deletes the snapshot from the list of known snapshots. No-op if the snapshot
// does not exist.
DeleteSnapshot(snapshotName string) error
// Return a copy of the known snapshots
GetSnapshots() map[string]*crdv1.VolumeSnapshot
// Check whether the specified snapshot exists
SnapshotExists(snapshotName string) bool
}
DesiredStateOfWorld defines a set of thread-safe operations supported on the snapshot controller's desired state of the world cache. This cache contains all the snapshots that should be created by the snapshot controller.
func NewDesiredStateOfWorld ¶
func NewDesiredStateOfWorld() DesiredStateOfWorld
NewDesiredStateOfWorld returns a new instance of DesiredStateOfWorld.
