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.
