Types

type Filter 

type Filter struct {
	// Labels is the set of labels to apply to the inputs
	Labels labelMap `yaml:"labels,omitempty"`

	// FsSlice identifies the label fields.
	FsSlice types.FsSlice
	// contains filtered or unexported fields
}

Filter sets labels.

Example

Code: 

{
	fss := builtinconfig.MakeDefaultConfig().CommonLabels
	err := kio.Pipeline{
		Inputs: []kio.Reader{&kio.ByteReader{Reader: bytes.NewBufferString(`
apiVersion: example.com/v1
kind: Foo
metadata:
  name: instance
---
apiVersion: example.com/v1
kind: Bar
metadata:
  name: instance
`)}},
		Filters: []kio.Filter{Filter{
			Labels: map[string]string{
				"foo": "bar",
			},
			FsSlice: fss,
		}},
		Outputs: []kio.Writer{kio.ByteWriter{Writer: os.Stdout}},
	}.Execute()
	if err != nil {
		log.Fatal(err)
	}

	// Output:
	// apiVersion: example.com/v1
	// kind: Foo
	// metadata:
	//   name: instance
	//   labels:
	//     foo: bar
	// ---
	// apiVersion: example.com/v1
	// kind: Bar
	// metadata:
	//   name: instance
	//   labels:
	//     foo: bar
}

Output:

apiVersion: example.com/v1
kind: Foo
metadata:
  name: instance
  labels:
    foo: bar
---
apiVersion: example.com/v1
kind: Bar
metadata:
  name: instance
  labels:
    foo: bar
