Overview ▾

Package replicacount contains a kio.Filter implementation of the kustomize ReplicaCountTransformer.

type Filter

Filter updates/sets replicas fields using the fieldSpecs 

type Filter struct {
    Replica   types.Replica   `json:"replica,omitempty" yaml:"replica,omitempty"`
    FieldSpec types.FieldSpec `json:"fieldSpec,omitempty" yaml:"fieldSpec,omitempty"`
    // contains filtered or unexported fields
}

▾ Example

Code:

err := kio.Pipeline{
    Inputs: []kio.Reader{&kio.ByteReader{Reader: bytes.NewBufferString(`
apiVersion: example.com/v1
kind: Foo
metadata:
  name: instance
spec:
  template:
    replicas: 5
---
apiVersion: example.com/v1
kind: Bar
metadata:
  name: instance
spec:
  template:
    replicas: 5
`)}},
    Filters: []kio.Filter{Filter{
        Replica: types.Replica{
            Count: 42,
            Name:  "instance",
        },
        FieldSpec: types.FieldSpec{
            Path: "spec/template/replicas",
        },
    }},
    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
spec:
  template:
    replicas: 42
---
apiVersion: example.com/v1
kind: Bar
metadata:
  name: instance
spec:
  template:
    replicas: 42

func (Filter) Filter 

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

func (*Filter) WithMutationTracker 

func (rc *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
