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 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.

func GetAccessModesFromString

func GetAccessModesFromString(modes string) []v1.PersistentVolumeAccessMode

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

func GetAvoidPodsFromNodeAnnotations

func GetAvoidPodsFromNodeAnnotations(annotations map[string]string) (v1.AvoidPods, error)

func GetMatchingTolerations

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

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

func GetPersistentVolumeClaimClass

func GetPersistentVolumeClaimClass(claim *v1.PersistentVolumeClaim) string

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

func GetPersistentVolumeClass

func GetPersistentVolumeClass(volume *v1.PersistentVolume) string

GetPersistentVolumeClass returns StorageClassName.

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 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 IsAttachableVolumeResourceName

func IsAttachableVolumeResourceName(name v1.ResourceName) bool

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 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 * namespace. Partially-qualified (unprefixed) names are implicitly in the 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 * namespace.

func IsScalarResourceName

func IsScalarResourceName(name v1.ResourceName) bool

Extended and Hugepages resources

func IsServiceIPSet

func IsServiceIPSet(service *v1.Service) bool

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

func LoadBalancerStatusDeepCopy

func LoadBalancerStatusDeepCopy(lb *v1.LoadBalancerStatus) *v1.LoadBalancerStatus

TODO: make method on LoadBalancerStatus?

func LoadBalancerStatusEqual

func LoadBalancerStatusEqual(l, r *v1.LoadBalancerStatus) bool

TODO: make method on LoadBalancerStatus?

func MatchNodeSelectorTerms

func MatchNodeSelectorTerms(
	nodeSelectorTerms []v1.NodeSelectorTerm,
	nodeLabels labels.Set,
	nodeFields fields.Set,
) bool

MatchNodeSelectorTerms checks whether the node labels and fields match node selector terms in ORed; nil or empty term matches no objects.

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 NodeSelectorRequirementsAsFieldSelector

func NodeSelectorRequirementsAsFieldSelector(nsm []v1.NodeSelectorRequirement) (fields.Selector, error)

NodeSelectorRequirementsAsFieldSelector converts the []NodeSelectorRequirement core type into a struct that implements fields.Selector.

func NodeSelectorRequirementsAsSelector

func NodeSelectorRequirementsAsSelector(nsm []v1.NodeSelectorRequirement) (labels.Selector, error)

NodeSelectorRequirementsAsSelector converts the []NodeSelectorRequirement api type into a struct that implements labels.Selector.

func ScopedResourceSelectorRequirementsAsSelector

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

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

func TolerationsTolerateTaint

func TolerationsTolerateTaint(tolerations []v1.Toleration, taint *v1.Taint) bool

TolerationsTolerateTaint checks if taint is tolerated by any of the tolerations.

func TolerationsTolerateTaintsWithFilter

func TolerationsTolerateTaintsWithFilter(tolerations []v1.Toleration, taints []v1.Taint, applyFilter taintsFilterFunc) bool
