Functions

func NewCheckpointState

func NewCheckpointState(stateDir, checkpointName string) (*stateCheckpoint, error)

NewCheckpointState creates new State for keeping track of claim info with checkpoint backend

Types

type CheckpointState

type CheckpointState interface {
	GetOrCreate() (ClaimInfoStateList, error)
	Store(ClaimInfoStateList) error
}

CheckpointState interface provides to get and store state

type ClaimInfoState

type ClaimInfoState struct {
	// Name of the DRA driver
	DriverName string

	// ClassName is a resource class of the claim
	ClassName string

	// ClaimUID is an UID of the resource claim
	ClaimUID types.UID

	// ClaimName is a name of the resource claim
	ClaimName string

	// Namespace is a claim namespace
	Namespace string

	// PodUIDs is a set of pod UIDs that reference a resource
	PodUIDs sets.Set[string]

	// CDIDevices is a map of DriverName --> CDI devices returned by the
	// GRPC API call NodePrepareResource
