AddOrUpdateTolerationInPod tries to add a toleration to the pod's toleration list. Returns true if something was updated, false otherwise.
AddOrUpdateTolerationInPodSpec tries to add a toleration to the toleration list in PodSpec. Returns true if something was updated, false otherwise.
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(modes string) []v1.PersistentVolumeAccessMode
GetAccessModesAsString returns an array of AccessModes from a string created by GetAccessModesAsString
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(claim *v1.PersistentVolumeClaim) string
GetPersistentVolumeClaimClass returns StorageClassName. If no storage class was requested, it returns "".
func GetPersistentVolumeClass(volume *v1.PersistentVolume) string
GetPersistentVolumeClass returns StorageClassName.
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.
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(name v1.ResourceName) bool
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(name v1.ResourceName) bool
IsHugePageResourceName returns true if the resource name has the huge page resource prefix.
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(name v1.ResourceName) bool
IsOvercommitAllowed returns true if the resource is in the default namespace and is not hugepages.
func IsPrefixedNativeResource(name v1.ResourceName) bool
IsPrefixedNativeResource returns true if the resource name is in the *kubernetes.io/ namespace.
func IsScalarResourceName(name v1.ResourceName) bool
Extended and Hugepages resources
this function aims to check if the service's ClusterIP is set or not the objective is not to perform validation here
func LoadBalancerStatusEqual(l, r *v1.LoadBalancerStatus) bool
TODO: make method on LoadBalancerStatus?
func MatchNodeSelectorTerms(
nodeSelectorTerms []v1.NodeSelectorTerm,
nodeLabels labels.Set,
nodeFields fields.Set,
) boolMatchNodeSelectorTerms checks whether the node labels and fields match node selector terms in ORed; nil or empty term matches no objects.
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(reqs []v1.NodeSelectorRequirement, terms []v1.NodeSelectorTerm) bool
NodeSelectorRequirementKeysExistInNodeSelectorTerms checks if a NodeSelectorTerm with key is already specified in terms
func NodeSelectorRequirementsAsFieldSelector(nsm []v1.NodeSelectorRequirement) (fields.Selector, error)
NodeSelectorRequirementsAsFieldSelector converts the []NodeSelectorRequirement core type into a struct that implements fields.Selector.
NodeSelectorRequirementsAsSelector converts the []NodeSelectorRequirement api type into a struct that implements labels.Selector.
func ScopedResourceSelectorRequirementsAsSelector(ssr v1.ScopedResourceSelectorRequirement) (labels.Selector, error)
ScopedResourceSelectorRequirementsAsSelector converts the ScopedResourceSelectorRequirement api type into a struct that implements labels.Selector.
TolerationsTolerateTaint checks if taint is tolerated by any of the tolerations.
func TolerationsTolerateTaintsWithFilter(tolerations []v1.Toleration, taints []v1.Taint, applyFilter taintsFilterFunc) bool
TolerationsTolerateTaintsWithFilter checks if given tolerations tolerates all the taints that apply to the filter in given taint list.
func TopologySelectorRequirementsAsSelector(tsm []v1.TopologySelectorLabelRequirement) (labels.Selector, error)
TopologySelectorRequirementsAsSelector converts the []TopologySelectorLabelRequirement api type into a struct that implements labels.Selector.
