Functions

func GetK8sObjType

func GetK8sObjType(obj metav1.Object) reflect.Type

GetK8sObjType returns the type (not the pointer type) of a kubernetes object.

func GroupVersionResourceToString

func GroupVersionResourceToString(gvr metav1.GroupVersionResource) string

GroupVersionResourceToString returns a string representation. It differs from the original stringer of the object itself.

func NewK8sObj

func NewK8sObj(t reflect.Type) metav1.Object

NewK8sObj returns a new object of a Kubernetes type based on the type.

func ToAdmissionErrorResponse

func ToAdmissionErrorResponse(uid types.UID, err error, logger log.Logger) *admissionv1beta1.AdmissionResponse

ToAdmissionErrorResponse transforms an error into a admission response with error.

Types

type ObjectCreator

type ObjectCreator interface {
	NewObject(rawJSON []byte) (runtime.Object, error)
}

ObjectCreator knows how to create objects from Raw JSON data into specific types.

func NewDynamicObjectCreator

func NewDynamicObjectCreator() ObjectCreator

NewDynamicObjectCreator returns a object creator that knows how to return objects from raw JSON data without the need of knowing the type.

To be able to infer the types the types need to be registered on the global client Scheme. Normally when a user tries casting the metav1.Object to a specific type, the object is already registered. In case the type is not registered and the object can't be created it will fallback to an Unstructured type.

Useful to make dynamic webhooks that expect multiple or unknown types.

func NewStaticObjectCreator

func NewStaticObjectCreator(obj metav1.Object) ObjectCreator

NewStaticObjectCreator doesn't need to infer the type, it will create a new schema and create a new object with the same type from the received object type.
