Functions

func AddOrUpdateTaint

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

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 DeleteTaint

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

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

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

func NewTaintsVar

func NewTaintsVar(ptr *[]api.Taint) taintsVar

NewTaintsVar wraps []api.Taint in a struct that implements flag.Value to allow taints to be bound to command line flags.

func ParseTaints

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

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

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

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 TaintSetDiff

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

func TaintSetFilter

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