func AddOrUpdateTolerationInPodSpec 

func AddOrUpdateTolerationInPodSpec(spec *v1.PodSpec, toleration *v1.Toleration) bool

AddOrUpdateTolerationInPodSpec tries to add a toleration to the toleration list in PodSpec. Returns true if something was updated, false otherwise.

func ContainsAccessMode 

func ContainsAccessMode(modes []v1.PersistentVolumeAccessMode, mode v1.PersistentVolumeAccessMode) bool

func GetAccessModesAsString 

func GetAccessModesAsString(modes []v1.PersistentVolumeAccessMode) string

GetAccessModesAsString returns a string representation of an array of access modes. modes, when present, are always in the same order: RWO,ROX,RWX,RWOP.

func GetAccessModesFromString 

func GetAccessModesFromString(modes string) []v1.PersistentVolumeAccessMode

GetAccessModesFromString returns an array of AccessModes from a string created by GetAccessModesAsString

func GetMatchingTolerations 

func GetMatchingTolerations(taints []v1.Taint, tolerations []v1.Toleration) (bool, []v1.Toleration)

GetMatchingTolerations returns true and list of Tolerations matching all Taints if all are tolerated, or false otherwise.

func HugePageResourceName 

func HugePageResourceName(pageSize resource.Quantity) v1.ResourceName

HugePageResourceName returns a ResourceName with the canonical hugepage prefix prepended for the specified page size. The page size is converted to its canonical representation.

func HugePageSizeFromMedium 

func HugePageSizeFromMedium(medium v1.StorageMedium) (resource.Quantity, error)

HugePageSizeFromMedium returns the page size for the specified huge page medium. If the specified input is not a valid huge page medium an error is returned.

func HugePageSizeFromResourceName 

func HugePageSizeFromResourceName(name v1.ResourceName) (resource.Quantity, error)

HugePageSizeFromResourceName returns the page size for the specified huge page resource name. If the specified input is not a valid huge page resource name an error is returned.

func HugePageUnitSizeFromByteSize 

func HugePageUnitSizeFromByteSize(size int64) (string, error)

HugePageUnitSizeFromByteSize returns hugepage size has the format. `size` must be guaranteed to divisible into the largest units that can be expressed. <size><unit-prefix>B (1024 = "1KB", 1048576 = "1MB", etc).

func IsAttachableVolumeResourceName 

func IsAttachableVolumeResourceName(name v1.ResourceName) bool

IsAttachableVolumeResourceName returns true when the resource name is prefixed in attachable volume

func IsExtendedResourceName 

func IsExtendedResourceName(name v1.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 IsHugePageMedium 

func IsHugePageMedium(medium v1.StorageMedium) bool

IsHugePageMedium returns true if the volume medium is in 'HugePages[-size]' format

func IsHugePageResourceName 

func IsHugePageResourceName(name v1.ResourceName) bool

IsHugePageResourceName returns true if the resource name has the huge page resource prefix.

func IsNativeResource 

func IsNativeResource(name v1.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 IsOvercommitAllowed 

func IsOvercommitAllowed(name v1.ResourceName) bool

IsOvercommitAllowed returns true if the resource is in the default namespace and is not hugepages.

func IsPrefixedNativeResource 

func IsPrefixedNativeResource(name v1.ResourceName) bool

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

func IsServiceIPSet 

func IsServiceIPSet(service *v1.Service) bool

IsServiceIPSet aims to check if the service's ClusterIP is set or not the objective is not to perform validation here

func MatchTopologySelectorTerms 

func MatchTopologySelectorTerms(topologySelectorTerms []v1.TopologySelectorTerm, lbls labels.Set) bool

MatchTopologySelectorTerms checks whether given labels match topology selector terms in ORed; nil or empty term matches no objects; while empty term list matches all objects.

func NodeSelectorRequirementKeysExistInNodeSelectorTerms 

func NodeSelectorRequirementKeysExistInNodeSelectorTerms(reqs []v1.NodeSelectorRequirement, terms []v1.NodeSelectorTerm) bool

NodeSelectorRequirementKeysExistInNodeSelectorTerms checks if a NodeSelectorTerm with key is already specified in terms

func ScopedResourceSelectorRequirementsAsSelector 

func ScopedResourceSelectorRequirementsAsSelector(ssr v1.ScopedResourceSelectorRequirement) (labels.Selector, error)

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

func TopologySelectorRequirementsAsSelector 

func TopologySelectorRequirementsAsSelector(tsm []v1.TopologySelectorLabelRequirement) (labels.Selector, error)

TopologySelectorRequirementsAsSelector converts the []TopologySelectorLabelRequirement api type into a struct that implements labels.Selector.
