Functions

func GetPersistentVolumeClaimClass

func GetPersistentVolumeClaimClass(claim *corev1.PersistentVolumeClaim) string

GetPersistentVolumeClaimClass returns StorageClassName. If no storage class was requested, it returns "".

func GetPodQOS

func GetPodQOS(pod *corev1.Pod) corev1.PodQOSClass

GetPodQOS returns the QoS class of a pod. 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 GetQuotaServiceType

func GetQuotaServiceType(service *corev1.Service) corev1.ServiceType

GetQuotaServiceType returns ServiceType if the service type is eligible to track against a quota, nor return ""

func IsExtendedResourceName

func IsExtendedResourceName(name corev1.ResourceName) bool

IsExtendedResourceName returns true if: 1. the resource name is not in the default namespace; 2. resource name does not have "requests." prefix, to avoid confusion with the convention in quota 3. it satisfies the rules in IsQualifiedName() after converted into quota resource name

func IsNativeResource

func IsNativeResource(name corev1.ResourceName) bool

IsNativeResource returns true if the resource name is in the *kubernetes.io/ namespace. Partially-qualified (unprefixed) names are implicitly in the kubernetes.io/ namespace.

func IsPrefixedNativeResource

func IsPrefixedNativeResource(name corev1.ResourceName) bool

IsPrefixedNativeResource returns true if the resource name is in the *kubernetes.io/ namespace.

func NewEvaluators

func NewEvaluators(f quota.ListerForResourceFunc) []quota.Evaluator

NewEvaluators returns the list of static evaluators that manage more than counts

func NewPersistentVolumeClaimEvaluator

func NewPersistentVolumeClaimEvaluator(f quota.ListerForResourceFunc) quota.Evaluator

NewPersistentVolumeClaimEvaluator returns an evaluator that can evaluate persistent volume claims

func NewPodEvaluator

func NewPodEvaluator(f quota.ListerForResourceFunc, clock clock.Clock) quota.Evaluator

NewPodEvaluator returns an evaluator that can evaluate pods

func NewServiceEvaluator

func NewServiceEvaluator(f quota.ListerForResourceFunc) quota.Evaluator

NewServiceEvaluator returns an evaluator that can evaluate services.

func PodUsageFunc

func PodUsageFunc(obj runtime.Object, clock clock.Clock) (corev1.ResourceList, error)

PodUsageFunc returns the quota usage for a pod. A pod is charged for quota if the following are not true.

• pod has a terminal phase (failed or succeeded)
• pod has been marked for deletion and grace period has expired

func QuotaV1Pod

func QuotaV1Pod(pod *corev1.Pod, clock clock.Clock) bool

QuotaV1Pod returns true if the pod is eligible to track against a quota if it's not in a terminal state according to its phase.

func ScopedResourceSelectorRequirementsAsSelector

func ScopedResourceSelectorRequirementsAsSelector(ssr corev1.ScopedResourceSelectorRequirement) (labels.Selector, error)

ScopedResourceSelectorRequirementsAsSelector converts the ScopedResourceSelectorRequirement api type into a struct that implements labels.Selector.

func V1ResourceByStorageClass

func V1ResourceByStorageClass(storageClass string, resourceName corev1.ResourceName) corev1.ResourceName

V1ResourceByStorageClass returns a quota resource name by storage class.

Types

type QOSList

type QOSList map[corev1.ResourceName]corev1.PodQOSClass

QOSList is a set of (resource name, QoS class) pairs.
