type KeysClearer ¶

type KeysClearer struct {
	Kind string   `yaml:"kind,omitempty"`
	Keys []string `yaml:"keys,omitempty"`

	// FsSlice identifies the location of the maps.
	FsSlice types.FsSlice `yaml:"fieldSpecs,omitempty"`
}

KeysClearer removes the key from the maps located at the entries specified by FsSlice.

N.B. this implements kio.Filter which takes returns []*yaml.RNode not yaml.Filter which takes/returns a single RNode; there's no good reason for this. Its just based on copying https://github.com/kubernetes-sigs/kustomize/blob/5993eae1aa78017c9e5922b41f2dba911e03ce6a/api/filters/labels/labels.go#L28

N.B jeremy@ couldn't get this to work when you have a list of maps and want to modify a field in the map e.g. spec:

items:
-  name: item1
   valuetokeep: v
   labels:
     toremove: a

Specifying a FieldSpec with path spec/items[] doesn't work; we get the wrong type of value Specifying a FieldSpec with path spec/items[]/labels does work but removes values from the nested nictionary.
