Functions

func AddObjectParams

func AddObjectParams(ws *restful.WebService, route *restful.RouteBuilder, obj interface{}, excludedNames ...string) error

AddObjectParams converts a runtime.Object into a set of go-restful Param() definitions on the route. The object must be a pointer to a struct; only fields at the top level of the struct that are not themselves interfaces or structs are used; only fields with a json tag that is non empty (the standard Go JSON behavior for omitting a field) become query parameters. The name of the query parameter is the JSON field name. If a description struct tag is set on the field, that description is used on the query parameter. In essence, it converts a standard JSON top level object into a query param schema.

func ConvertGroupVersionIntoToDiscovery

func ConvertGroupVersionIntoToDiscovery(list []metav1.APIResource) ([]apidiscoveryv2.APIResourceDiscovery, error)

func GetArticleForNoun

func GetArticleForNoun(noun string, padding string) string

GetArticleForNoun returns the article needed for the given noun.

func GetResourceKind

func GetResourceKind(groupVersion schema.GroupVersion, storage rest.Storage, typer runtime.ObjectTyper) (schema.GroupVersionKind, error)

GetResourceKind returns the external group version kind registered for the given storage object. If the storage object is a subresource and has an override supplied for it, it returns the group version kind supplied in the override.

Types

type APIGroupVersion

type APIGroupVersion struct {
	Storage map[string]rest.Storage

	Root string

	// GroupVersion is the external group version
	GroupVersion schema.GroupVersion

	// AllServedVersionsByResource is indexed by resource and maps to a list of versions that resource exists in.
	// This was created so that StorageVersion for APIs can include a list of all version that are served for each
	// GroupResource tuple.
	AllServedVersionsByResource map[string][]string

	// OptionsExternalVersion controls the Kubernetes APIVersion used for common objects in the apiserver
	// schema like api.Status, api.DeleteOptions, and metav1.ListOptions. Other implementors may
	// define a version "v1beta1" but want to use the Kubernetes "v1" internal objects. If
	// empty, defaults to GroupVersion.
	OptionsExternalVersion *schema.GroupVersion
	// MetaGroupVersion defaults to "meta.k8s.io/v1" and is the scheme group version used to decode
	// common API implementations like ListOptions. Future changes will allow this to vary by group
	// version (for when the inevitable meta/v2 group emerges).
	MetaGroupVersion *schema.GroupVersion

	// RootScopedKinds are the root scoped kinds for the primary GroupVersion
	RootScopedKinds sets.String

	// Serializer is used to determine how to convert responses from API methods into bytes to send over
	// the wire.
	Serializer     runtime.NegotiatedSerializer
	ParameterCodec runtime.ParameterCodec

	Typer                 runtime.ObjectTyper
	Creater               runtime.ObjectCreater
	Convertor             runtime.ObjectConvertor
	ConvertabilityChecker ConvertabilityChecker

	Namer                 runtime.Namer
	UnsafeConvertor       runtime.ObjectConvertor
	TypeConverter         managedfields.TypeConverter

	EquivalentResourceRegistry runtime.EquivalentResourceRegistry

	// Authorizer determines whether a user is allowed to make a certain request. The Handler does a preliminary
	// authorization check using the request URI but it may be necessary to make additional checks, such as in
	// the create-on-update case
	Authorizer authorizer.Authorizer

	Admit admission.Interface

	MinRequestTimeout time.Duration

	// The limit on the request body size that would be accepted and decoded in a write request.
	// 0 means no limit.
	MaxRequestBodyBytes int64
}

APIGroupVersion is a helper for exposing rest.Storage objects as http.Handlers via go-restful It handles URLs of the form: /${storage_key}[/${object_name}] Where 'storage_key' points to a rest.Storage object stored in storage. This object should contain all parameterization necessary for running a particular API version

func (*APIGroupVersion) InstallREST

func (g *APIGroupVersion) InstallREST(container *restful.Container) ([]apidiscoveryv2.APIResourceDiscovery, []*storageversion.ResourceInfo, error)

InstallREST registers the REST handlers (storage, watch, proxy and redirect) into a restful Container. It is expected that the provided path root prefix will serve all operations. Root MUST NOT end in a slash.

type APIInstaller

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

func (*APIInstaller) Install

func (a *APIInstaller) Install() ([]metav1.APIResource, []*storageversion.ResourceInfo, *restful.WebService, []error)

Install handlers for API resources.

type ConvertabilityChecker

type ConvertabilityChecker interface {
	// VersionsForGroupKind indicates what versions are available to convert a group kind. This determines
	// what our decoding abilities are.
	VersionsForGroupKind(gk schema.GroupKind) []schema.GroupVersion
}

ConvertabilityChecker indicates what versions a GroupKind is available in.

type StorageMetricsOverride

type StorageMetricsOverride interface {
	// OverrideMetricsVerb gives a storage object an opportunity to override the verb reported to the metrics endpoint
	OverrideMetricsVerb(oldVerb string) (newVerb string)
}

An interface to see if one storage supports override its default verb for monitoring
