package apiutil

import "github.com/kubernetes-sigs/controller-runtime/pkg/client/apiutil"

Package apiutil contains utilities for working with raw Kubernetes API machinery, such as creating RESTMappers and raw REST clients, and extracting the GVK of an object.

apimachinery.go dynamicrestmapper.go

func GVKForObject Uses

func GVKForObject(obj runtime.Object, scheme *runtime.Scheme) (schema.GroupVersionKind, error)

GVKForObject finds the GroupVersionKind associated with the given object, if there is only a single such GVK.

func NewDiscoveryRESTMapper Uses

func NewDiscoveryRESTMapper(c *rest.Config) (meta.RESTMapper, error)

NewDiscoveryRESTMapper constructs a new RESTMapper based on discovery information fetched by a new client with the given config.

func NewDynamicRESTMapper Uses

func NewDynamicRESTMapper(cfg *rest.Config, opts ...DynamicRESTMapperOption) (meta.RESTMapper, error)

NewDynamicRESTMapper returns a dynamic RESTMapper for cfg. The dynamic RESTMapper dynamically discovers resource types at runtime. opts configure the RESTMapper.

func RESTClientForGVK Uses

func RESTClientForGVK(gvk schema.GroupVersionKind, baseConfig *rest.Config, codecs serializer.CodecFactory) (rest.Interface, error)

RESTClientForGVK constructs a new rest.Interface capable of accessing the resource associated with the given GroupVersionKind. The REST client will be configured to use the negotiated serializer from baseConfig, if set, otherwise a default serializer will be set.

type DynamicRESTMapperOption Uses

type DynamicRESTMapperOption func(*dynamicRESTMapper) error

DynamicRESTMapperOption is a functional option on the dynamicRESTMapper

var WithLazyDiscovery DynamicRESTMapperOption = func(drm *dynamicRESTMapper) error {
    drm.lazy = true
    return nil
}

WithLazyDiscovery prevents the RESTMapper from discovering REST mappings until an API call is made.

func WithCustomMapper Uses

func WithCustomMapper(newMapper func() (meta.RESTMapper, error)) DynamicRESTMapperOption

WithCustomMapper supports setting a custom RESTMapper refresher instead of the default method, which uses a discovery client.

This exists mainly for testing, but can be useful if you need tighter control over how discovery is performed, which discovery endpoints are queried, etc.

func WithLimiter Uses

func WithLimiter(lim *rate.Limiter) DynamicRESTMapperOption

WithLimiter sets the RESTMapper's underlying limiter to lim.
