Functions

func BuildRestMapper

func BuildRestMapper(restConfig *rest.Config) (meta.RESTMapper, error)

func CreateAnew

func CreateAnew(client resource.Interface, obj runtime.Object, deleteOptions *metav1.DeleteOptions) error

CreateAnew creates a resource, first deleting an existing instance if one exists. If the delete options specify that deletion should be propagated in the foreground, this will wait for the deletion to be complete before creating the new object: with foreground propagation, Get will continue to return the object being deleted and Create will fail with “already exists” until deletion is complete.

func FindGroupVersionResource

func FindGroupVersionResource(from *unstructured.Unstructured, restMapper meta.RESTMapper) (*schema.GroupVersionResource, error)

func GetMetadata

func GetMetadata(from *unstructured.Unstructured) map[string]interface{}

func GetNestedField

func GetNestedField(obj *unstructured.Unstructured, fields ...string) interface{}

func GetSpec

func GetSpec(obj *unstructured.Unstructured) interface{}

func SetBackoff

func SetBackoff(b wait.Backoff) wait.Backoff

func ToUnstructuredResource

func ToUnstructuredResource(from runtime.Object, restMapper meta.RESTMapper) (*unstructured.Unstructured, *schema.GroupVersionResource,
	error)

Types

type MutateFn

type MutateFn func(existing runtime.Object) (runtime.Object, error)

func Replace

type OperationResult

type OperationResult string

const (
	OperationResultNone    OperationResult = "unchanged"
	OperationResultCreated OperationResult = "created"
	OperationResultUpdated OperationResult = "updated"
)

func CreateOrUpdate

func CreateOrUpdate(client resource.Interface, obj runtime.Object, mutate MutateFn) (OperationResult, error)
