Functions

func AddObjectAnnotations

func AddObjectAnnotations(obj runtime.Object, annotations map[string]string) error

AddObjectAnnotations adds new annotation(s) to a single runtime.Object

func AddObjectLabels

func AddObjectLabels(obj runtime.Object, labels labels.Set) error

AddObjectLabels adds new label(s) to a single runtime.Object

func MergeInto

func MergeInto(dst, src interface{}, flags int) error

MergeInto merges items from a src map into a dst map. Returns an error when the maps are not of the same type. Flags:

• ErrorOnExistingDstKey When set: Return an error if any of the dst keys is already set.
• ErrorOnDifferentDstKeyValue When set: Return an error if any of the dst keys is already set to a different value than src key.
• OverwriteDstKey When set: Overwrite existing dst key value with src key value.

func NoNamespaceKeyFunc

func NoNamespaceKeyFunc(ctx kapi.Context, prefix string, name string) (string, error)

NoNamespaceKeyFunc is the default function for constructing etcd paths to a resource relative to prefix enforcing If a namespace is on context, it errors.

func UniqueStrings

func UniqueStrings(strings []string) []string

UniqueStrings returns a sorted, uniquified slice of the specified strings
