Types

type File

type File struct {
	Data struct {
		PodDeviceEntries []PodDevicesEntry
	}
}

File is representing the kubelet checkpoint file structure with only relevant fields - valid until K8s 1.20 TODO: REMOVE THIS TPYE AFTER 1.20 SUPPORT IS DROPPED

func TranslateNewCheckpointToOld

func TranslateNewCheckpointToOld(newFile NewFile) File

TranslateNewCheckpointToOld downgrades from an 1.21+ checkpoint file representation to the old format It simply merges all the NUMA specififc DeviceID string slices into one big slice Enables code re-use without needing to modify the business logic of an Operator needing to simultaneously support pre, and post 1.21 K8s versions

type NewFile

type NewFile struct {
	Data struct {
		PodDeviceEntries []NewPodDevicesEntry
	}
}

NewFile is representing the kubelet checkpoint file structure with only relevant fields - valid from K8s 1.21 onward Reference: https://github.com/kubernetes/kubernetes/commit/a8b8995ef241e93e9486d475126450f33f24ef4e

type NewPodDevicesEntry

type NewPodDevicesEntry struct {
	PodUID        string
	ContainerName string
	ResourceName  string
	DeviceIDs     cp.DevicesPerNUMA //map[int64][]string
}

NewPodDevicesEntry is representing Pod specific deviceID allocations from kubelet checkpoint file structure - valid from K8s 1.21 onward Reference: https://github.com/kubernetes/kubernetes/commit/a8b8995ef241e93e9486d475126450f33f24ef4e
