Functions

func ComputePodQOS

func ComputePodQOS(pod *v1.Pod) v1.PodQOSClass

ComputePodQOS evaluates the list of containers to determine a pod's QoS class. This function is more expensive than GetPodQOS which should be used for pods having a non-empty .Status.QOSClass. A pod is besteffort if none of its containers have specified any requests or limits. A pod is guaranteed only when requests and limits are specified for all the containers and they are equal. A pod is burstable if limits and requests do not match across all containers.

func GetPodQOS

func GetPodQOS(pod *v1.Pod) v1.PodQOSClass

GetPodQOS returns the QoS class of a pod persisted in the PodStatus.QOSClass field. If PodStatus.QOSClass is empty, it returns value of ComputePodQOS() which evaluates pod's QoS class.

Types

type QOSList

type QOSList map[v1.ResourceName]v1.PodQOSClass
