Functions

func AddOrUpdateTaint

func AddOrUpdateTaint(node *v1.Node, taint *v1.Taint) (*v1.Node, bool, error)

Tries to add a taint to annotations list. Returns a new copy of updated Node and true if something was updated false otherwise.

func AddOrUpdateTolerationInPod

func AddOrUpdateTolerationInPod(pod *v1.Pod, toleration *v1.Toleration) bool

AddOrUpdateTolerationInPod tries to add a toleration to the pod's toleration list. Returns true if something was updated, false otherwise.

func AddToNodeAddresses

func AddToNodeAddresses(addresses *[]v1.NodeAddress, addAddresses ...v1.NodeAddress)

AddToNodeAddresses appends the NodeAddresses to the passed-by-pointer slice, only if they do not already exist

func DeleteTaint

func DeleteTaint(taints []v1.Taint, taintToDelete *v1.Taint) ([]v1.Taint, bool)

DeleteTaint removes all the the taints that have the same key and effect to given taintToDelete.

func DeleteTaintsByKey

func DeleteTaintsByKey(taints []v1.Taint, taintKey string) ([]v1.Taint, bool)

DeleteTaintsByKey removes all the taints that have the same key to given taintKey

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 GetAffinityFromPodAnnotations

func GetAffinityFromPodAnnotations(annotations map[string]string) (*v1.Affinity, error)

GetAffinityFromPodAnnotations gets the json serialized affinity data from Pod.Annotations and converts it to the Affinity type in api. TODO: remove when alpha support for affinity is removed

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 IsOpaqueIntResourceName

func IsOpaqueIntResourceName(name v1.ResourceName) bool

IsOpaqueIntResourceName returns true if the resource name has the opaque integer resource prefix.

func IsServiceIPRequested

func IsServiceIPRequested(service *v1.Service) bool

this function aims to check if the service's cluster IP is requested or not

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 NodeSelectorRequirementsAsSelector

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

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

func OpaqueIntResourceName

func OpaqueIntResourceName(name string) v1.ResourceName

OpaqueIntResourceName returns a ResourceName with the canonical opaque integer prefix prepended. If the argument already has the prefix, it is returned unmodified.

func PersistentVolumeClaimHasClass

func PersistentVolumeClaimHasClass(claim *v1.PersistentVolumeClaim) bool

PersistentVolumeClaimHasClass returns true if given claim has set StorageClassName field.

func PodAnnotationsFromSysctls

func PodAnnotationsFromSysctls(sysctls []v1.Sysctl) string

PodAnnotationsFromSysctls creates an annotation value for a slice of Sysctls.

func RemoveTaint

func RemoveTaint(node *v1.Node, taint *v1.Taint) (*v1.Node, bool, error)

Tries to remove a taint from annotations list. Returns a new copy of updated Node and true if something was updated false otherwise.

func SysctlsFromPodAnnotation

func SysctlsFromPodAnnotation(annotation string) ([]v1.Sysctl, error)

SysctlsFromPodAnnotation parses an annotation value into a slice of Sysctls.

func SysctlsFromPodAnnotations

func SysctlsFromPodAnnotations(a map[string]string) ([]v1.Sysctl, []v1.Sysctl, error)

SysctlsFromPodAnnotations parses the sysctl annotations into a slice of safe Sysctls and a slice of unsafe Sysctls. This is only a convenience wrapper around SysctlsFromPodAnnotation.

func TaintExists

func TaintExists(taints []v1.Taint, taintToFind *v1.Taint) bool

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

TolerationsTolerateTaintsWithFilter checks if given tolerations tolerates all the taints that apply to the filter in given taint list.
