Functions

func IsGroupDiscoveryFailedError

func IsGroupDiscoveryFailedError(err error) bool

IsGroupDiscoveryFailedError returns true if the provided error indicates the server was unable to discover a complete list of APIs for the client to use.

func NewRESTMapper

func NewRESTMapper(groupResources []*APIGroupResources, versionInterfaces meta.VersionInterfacesFunc) meta.RESTMapper

NewRESTMapper returns a PriorityRESTMapper based on the discovered groups and resourced passed in.

Types

type APIGroupResources

type APIGroupResources struct {
	Group unversioned.APIGroup
	// A mapping of version string to a slice of APIResources for
	// that version.
	VersionedResources map[string][]unversioned.APIResource
}

APIGroupResources is an API group with a mapping of versions to resources.

func GetAPIGroupResources

func GetAPIGroupResources(cl DiscoveryInterface) ([]*APIGroupResources, error)

GetAPIGroupResources uses the provided discovery client to gather discovery information and populate a slice of APIGroupResources.

type DeferredDiscoveryRESTMapper

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

DeferredDiscoveryRESTMapper is a RESTMapper that will defer initialization of the RESTMapper until the first mapping is requested.

func NewDeferredDiscoveryRESTMapper

func NewDeferredDiscoveryRESTMapper(cl DiscoveryInterface, versionInterface meta.VersionInterfacesFunc) *DeferredDiscoveryRESTMapper

NewDeferredDiscoveryRESTMapper returns a DeferredDiscoveryRESTMapper that will lazily query the provided client for discovery information to do REST mappings.

func (*DeferredDiscoveryRESTMapper) AliasesForResource

func (d *DeferredDiscoveryRESTMapper) AliasesForResource(resource string) ([]string, bool)

AliasesForResource returns whether a resource has an alias or not.

func (*DeferredDiscoveryRESTMapper) KindFor

KindFor takes a partial resource and returns back the single match. It returns an error if there are multiple matches.

func (*DeferredDiscoveryRESTMapper) KindsFor

func (*DeferredDiscoveryRESTMapper) RESTMapping

func (d *DeferredDiscoveryRESTMapper) RESTMapping(gk unversioned.GroupKind, versions ...string) (*meta.RESTMapping, error)

RESTMapping identifies a preferred resource mapping for the provided group kind.

func (*DeferredDiscoveryRESTMapper) RESTMappings

RESTMappings returns the RESTMappings for the provided group kind in a rough internal preferred order. If no kind is found, it will return a NoResourceMatchError.

func (*DeferredDiscoveryRESTMapper) Reset

func (d *DeferredDiscoveryRESTMapper) Reset()

Reset resets the internally cached Discovery information and will cause the next mapping request to re-discover.

func (*DeferredDiscoveryRESTMapper) ResourceFor

ResourceFor takes a partial resource and returns back the single match. It returns an error if there are multiple matches.

func (*DeferredDiscoveryRESTMapper) ResourceSingularizer

func (d *DeferredDiscoveryRESTMapper) ResourceSingularizer(resource string) (singular string, err error)

ResourceSingularizer converts a resource name from plural to singular (e.g., from pods to pod).

func (*DeferredDiscoveryRESTMapper) ResourcesFor

ResourcesFor takes a partial resource and returns back the list of potential resource in priority order.

func (*DeferredDiscoveryRESTMapper) String

func (d *DeferredDiscoveryRESTMapper) String() string

type DiscoveryClient

type DiscoveryClient struct {
	*rest.RESTClient

	LegacyPrefix string
}

DiscoveryClient implements the functions that discover server-supported API groups, versions and resources.

func NewDiscoveryClient

func NewDiscoveryClient(c *rest.RESTClient) *DiscoveryClient

New creates a new DiscoveryClient for the given RESTClient.

func NewDiscoveryClientForConfig

func NewDiscoveryClientForConfig(c *rest.Config) (*DiscoveryClient, error)

NewDiscoveryClientForConfig creates a new DiscoveryClient for the given config. This client can be used to discover supported resources in the API server.

func NewDiscoveryClientForConfigOrDie

func NewDiscoveryClientForConfigOrDie(c *rest.Config) *DiscoveryClient

NewDiscoveryClientForConfig creates a new DiscoveryClient for the given config. If there is an error, it panics.

func (*DiscoveryClient) ServerGroups

func (d *DiscoveryClient) ServerGroups() (apiGroupList *unversioned.APIGroupList, err error)

ServerGroups returns the supported groups, with information like supported versions and the preferred version.

func (*DiscoveryClient) ServerPreferredNamespacedResources

func (d *DiscoveryClient) ServerPreferredNamespacedResources() ([]unversioned.GroupVersionResource, error)

ServerPreferredNamespacedResources returns the supported namespaced resources with the version preferred by the server.

func (*DiscoveryClient) ServerPreferredResources

func (d *DiscoveryClient) ServerPreferredResources() ([]unversioned.GroupVersionResource, error)

ServerPreferredResources returns the supported resources with the version preferred by the server.

func (*DiscoveryClient) ServerResources

func (d *DiscoveryClient) ServerResources() (map[string]*unversioned.APIResourceList, error)

ServerResources returns the supported resources for all groups and versions.

func (*DiscoveryClient) ServerResourcesForGroupVersion

func (d *DiscoveryClient) ServerResourcesForGroupVersion(groupVersion string) (resources *unversioned.APIResourceList, err error)

ServerResourcesForGroupVersion returns the supported resources for a group and version.

func (*DiscoveryClient) ServerVersion

func (d *DiscoveryClient) ServerVersion() (*version.Info, error)

ServerVersion retrieves and parses the server's version (git version).

func (*DiscoveryClient) SwaggerSchema

func (d *DiscoveryClient) SwaggerSchema(version unversioned.GroupVersion) (*swagger.ApiDeclaration, error)

SwaggerSchema retrieves and parses the swagger API schema the server supports.

type DiscoveryInterface

DiscoveryInterface holds the methods that discover server-supported API groups, versions and resources.

type ErrGroupDiscoveryFailed

type ErrGroupDiscoveryFailed struct {
	// Groups is a list of the groups that failed to load and the error cause
	Groups map[unversioned.GroupVersion]error
}

ErrGroupDiscoveryFailed is returned if one or more API groups fail to load.

func (*ErrGroupDiscoveryFailed) Error

UnstructuredObjectTyper provides a runtime.ObjectTyper implmentation for runtime.Unstructured object based on discovery information.

func NewUnstructuredObjectTyper

func NewUnstructuredObjectTyper(groupResources []*APIGroupResources) *UnstructuredObjectTyper

NewUnstructuredObjectTyper returns a runtime.ObjectTyper for unstructred objects based on discovery information.

func (*UnstructuredObjectTyper) IsUnversioned

func (d *UnstructuredObjectTyper) IsUnversioned(obj runtime.Object) (unversioned bool, ok bool)

IsUnversioned returns false always because *runtime.Unstructured objects should always have group,version,kind information set. ok will be true if the object's group,version,kind is registered.

func (*UnstructuredObjectTyper) ObjectKind

ObjectKind returns the group,version,kind of the provided object, or an error if the object in not *runtime.Unstructured or has no group,version,kind information.
