Data string `json:"data"`
// Checksum is a checksum of Data
Checksum checksum.Checksum `json:"checksum"`
}
Checkpoint represents a structure to store pod resource allocation checkpoint data
func NewCheckpoint ¶
func NewCheckpoint(allocations *PodResourceCheckpointInfo) (*Checkpoint, error)
NewCheckpoint creates a new checkpoint from a list of claim info states
func (*Checkpoint) GetPodResourceCheckpointInfo ¶
func (cp *Checkpoint) GetPodResourceCheckpointInfo() (*PodResourceCheckpointInfo, error)
GetPodResourceCheckpointInfo returns Pod Resource Allocation info states from checkpoint
func (*Checkpoint) MarshalCheckpoint ¶

type PodResourceCheckpointInfo ¶
type PodResourceCheckpointInfo struct {
Entries PodResourceInfoMap `json:"entries,omitempty"`
}
type PodResourceInfo ¶
type PodResourceInfo struct {
// ContainerResources maps container names to their respective ResourceRequirements.
ContainerResources map[string]v1.ResourceRequirements
}
PodResourceInfo stores resource requirements for containers within a pod.
type PodResourceInfoMap ¶
type PodResourceInfoMap map[types.UID]PodResourceInfo
PodResourceInfoMap maps pod UIDs to their corresponding PodResourceInfo, tracking resource requirements for all containers within each pod.
func (PodResourceInfoMap) Clone ¶

type Reader interface {
GetContainerResources(podUID types.UID, containerName string) (v1.ResourceRequirements, bool)
GetPodResourceInfoMap() PodResourceInfoMap
}
Reader interface used to read current pod resource state
type State ¶
type State interface {
Reader
// contains filtered or unexported methods
}
State interface provides methods for tracking and setting pod resources
func NewNoopStateCheckpoint ¶
func NewNoopStateCheckpoint() State
NewNoopStateCheckpoint creates a dummy state checkpoint manager
func NewStateCheckpoint ¶
NewStateCheckpoint creates new State for keeping track of pod resource information with checkpoint backend
func NewStateMemory ¶
