Functions

func GetDependsOnMap

func GetDependsOnMap(objects []*fn.KubeObject) map[string]bool

GetDependsOnMap iterates `objects` to get the annotation which contains namespace value.

func ReplaceNamespace

func ReplaceNamespace(objects []*fn.KubeObject, newNs string, count *int, oldNamespace map[string]struct{})

ReplaceNamespace iterates the `objects` to replace the `OldNs` with `newNs` on namespace field.

func SetNamespace

func SetNamespace(rl *fn.ResourceList) (bool, error)

func UpdateAnnotation

func UpdateAnnotation(objects []*fn.KubeObject, newNs string, oldNs map[string]struct{}, dependsOnMap map[string]bool)

UpdateAnnotation updates the `objects`'s "config.kubernetes.io/depends-on" annotation which contains namespace value.

func VisitNamespaces

func VisitNamespaces(objects []*fn.KubeObject, visitor func(namespace *Namespace))

VisitNamespaces iterates the `objects` to execute the `visitor` function on each corresponding namespace field.

Types

type Namespace

type Namespace struct {
	Ptr                 *string
	IsNamespace         bool
	DependsOnAnnotation string
	// contains filtered or unexported fields
}

func NewNamespace

func NewNamespace(obj *fn.KubeObject, namespacePtr *string) *Namespace

func (*Namespace) GetDependsOnAnnotation

func (n *Namespace) GetDependsOnAnnotation() string

func (*Namespace) SetDependsOnAnnotation

func (n *Namespace) SetDependsOnAnnotation(newDependsOn string)

type NamespaceTransformer

type NamespaceTransformer struct {
	NewNamespace string
	DependsOnMap map[string]bool
	Errors       []string
}

func (*NamespaceTransformer) Config

func (p *NamespaceTransformer) Config(o *fn.KubeObject) error

Config gets the attributes from different FunctionConfig formats.

func (*NamespaceTransformer) LogResults

func (p *NamespaceTransformer) LogResults(rl *fn.ResourceList, count int, oldNamespaces map[string]struct{}) *fn.Result

func (*NamespaceTransformer) Transform

func (p *NamespaceTransformer) Transform(objects []*fn.KubeObject, oldNamespaces map[string]struct{}) int

Transform replace the existing Namespace object, namespace-scoped resources' `metadata.name` and other namespace reference fields to the new value.
