Types

type Filter

type Filter struct {
	ImageOverride []v1alpha1.ImageOverride `json:"imageOverride,omitempty" yaml:"override,omitempty"`

	// FsSlice contains the FieldSpecs to locate an image field,

Example

err := kio.Pipeline{
	Inputs: []kio.Reader{&kio.ByteReader{Reader: bytes.NewBufferString(`
apiVersion: example.com/v1
kind: Foo
metadata:
  name: instance
spec:
  containers:
  - name: FooBar
    image: nginx:1.2.1
---
apiVersion: example.com/v1
kind: Bar
metadata:
  name: instance
spec:
  containers:
  - name: BarFoo
    image: nginx:2.1.2 
`)}},
	Filters: []kio.Filter{Filter{
		ImageOverride: []corev1alpha1.ImageOverride{
			{
				Registry:    "docker.io",
				NewRegistry: "docker.cc",
			},
		},
		FsSlice: []types.FieldSpec{
			{
				Path: "spec/containers[]/image",
			},
		},
	}},
	Outputs: []kio.Writer{kio.ByteWriter{Writer: os.Stdout}},

	log.Fatal(err)

Output:

func (Filter) Filter

func (f Filter) Filter(nodes []*yaml.RNode) ([]*yaml.RNode, error)

func (*Filter) WithMutationTracker

func (f *Filter) WithMutationTracker(callback func(key, value, tag string, node *yaml.RNode))

WithMutationTracker registers a callback which will be invoked each time a field is mutated
