Documentation

Overview

Package scale provides a polymorphic scale client capable of fetching and updating Scale for any resource which implements the `scale` subresource, as long as that subresource operates on a version of scale convertable to autoscaling.Scale.

Types

type ScaleConverter

type ScaleConverter struct {
	// contains filtered or unexported fields
}

ScaleConverter knows how to convert between external scale versions.

func NewScaleConverter

func NewScaleConverter() *ScaleConverter

NewScaleConverter creates a new ScaleConverter for converting between Scales in autoscaling/v1 and extensions/v1beta1.

func (*ScaleConverter) ConvertToVersion

func (c *ScaleConverter) ConvertToVersion(in runtime.Object, outVersion schema.GroupVersion) (runtime.Object, error)

ConvertToVersion converts the given *external* input object to the given output *external* output group-version.

func (*ScaleConverter) Scheme

func (c *ScaleConverter) Scheme() *runtime.Scheme

Scheme returns the scheme used by this scale converter.

type ScaleInterface

type ScaleInterface interface {
	// Get fetches the scale of the given scalable resource.
	Get(resource schema.GroupResource, name string) (*autoscalingapi.Scale, error)

	// Update updates the scale of the the given scalable resource.
	Update(resource schema.GroupResource, scale *autoscalingapi.Scale) (*autoscalingapi.Scale, error)
}

ScaleInterface can fetch and update scales for resources in a particular namespace which implement the scale subresource.

type ScaleKindResolver

type ScaleKindResolver interface {
	// ScaleForResource returns the GroupVersionKind of the
	// scale subresource for the given GroupVersionResource.
	ScaleForResource(resource schema.GroupVersionResource) (scaleVersion schema.GroupVersionKind, err error)
}

ScaleKindResolver knows about the relationship between resources and the GroupVersionKind of their scale subresources.

func NewDiscoveryScaleKindResolver

func NewDiscoveryScaleKindResolver(client discovery.ServerResourcesInterface) ScaleKindResolver

NewDiscoveryScaleKindResolver creates a new ScaleKindResolver which uses information from the given disovery client to resolve the correct Scale GroupVersionKind for different resources.

type ScalesGetter

type ScalesGetter interface {
	Scales(namespace string) ScaleInterface
}

ScalesGetter can produce a ScaleInterface for a particular namespace.

func New

func New(baseClient restclient.Interface, mapper meta.RESTMapper, resolver dynamic.APIPathResolverFunc, scaleKindResolver ScaleKindResolver) ScalesGetter

New creates a new ScalesGetter using the given client to make requests. The GroupVersion on the client is ignored.

func NewForConfig

func NewForConfig(cfg *restclient.Config, mapper meta.RESTMapper, resolver dynamic.APIPathResolverFunc, scaleKindResolver ScaleKindResolver) (ScalesGetter, error)

NewForConfig creates a new ScalesGetter which resolves kinds to resources using the given RESTMapper, and API paths using the given dynamic.APIPathResolverFunc.
