Functions

func AddOrUpdateTaint added in v1.8.0

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

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

func CheckIfTaintsAlreadyExists added in v1.8.0

func CheckIfTaintsAlreadyExists(oldTaints []v1.Taint, taints []v1.Taint) string

CheckIfTaintsAlreadyExists checks if the node already has taints that we want to add and returns a string with taint keys.

func CheckTaintValidation added in v1.23.0

func CheckTaintValidation(taint v1.Taint) error

CheckTaintValidation checks if the given taint is valid. Returns error if the given taint is invalid.

func DeleteTaint added in v1.8.0

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

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

func DeleteTaintsByKey added in v1.8.0

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

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

func ParseTaints added in v1.8.0

func ParseTaints(spec []string) ([]v1.Taint, []v1.Taint, error)

ParseTaints takes a spec which is an array and creates slices for new taints to be added, taints to be deleted. It also validates the spec. For example, the form `<key>` may be used to remove a taint, but not to add one.

func RemoveTaint added in v1.8.0

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

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

func ReorganizeTaints added in v1.8.0

func ReorganizeTaints(node *v1.Node, overwrite bool, taintsToAdd []v1.Taint, taintsToRemove []v1.Taint) (string, []v1.Taint, error)

ReorganizeTaints returns the updated set of taints, taking into account old taints that were not updated, old taints that were updated, old taints that were deleted, and new taints.

func TaintExists added in v1.8.0

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

TaintExists checks if the given taint exists in list of taints. Returns true if exists false otherwise.

func TaintKeyExists added in v1.24.0

func TaintKeyExists(taints []v1.Taint, taintKeyToMatch string) bool

TaintKeyExists checks if the given taint key exists in list of taints. Returns true if exists false otherwise.

func TaintSetDiff added in v1.8.0

func TaintSetDiff(t1, t2 []v1.Taint) (taintsToAdd []*v1.Taint, taintsToRemove []*v1.Taint)

func TaintSetFilter added in v1.8.0

func TaintSetFilter(taints []v1.Taint, fn func(*v1.Taint) bool) []v1.Taint
