Functions

func GetOverrideHash

func GetOverrideHash(rawObj *unstructured.Unstructured) (string, error)

func GetTemplateHash

func GetTemplateHash(fieldMap map[string]interface{}) (string, error)

func StartFederationSyncController

func StartFederationSyncController(controllerConfig *util.ControllerConfig, stopChan <-chan struct{}, typeConfig typeconfig.Interface, fedNamespaceAPIResource *metav1.APIResource) error

StartFederationSyncController starts a new sync controller for a type config

Types

type FederatedResource

type FederatedResource interface {
	dispatch.FederatedResourceForDispatch

	FederatedName() util.QualifiedName
	FederatedKind() string
	UpdateVersions(selectedClusters []string, versionMap map[string]string) error
	DeleteVersions()
	ComputePlacement(clusters []*fedv1b1.KubeFedCluster) (selectedClusters sets.String, err error)
	IsNamespaceInHostCluster(clusterObj pkgruntime.Object) bool
}

FederatedResource encapsulates the behavior of a logical federated resource which may be implemented by one or more kubernetes resources in the cluster hosting the kubefed control plane.

type FederatedResourceAccessor

type FederatedResourceAccessor interface {
	Run(stopChan <-chan struct{})
	HasSynced() bool
	FederatedResource(qualifiedName util.QualifiedName) (federatedResource FederatedResource, possibleOrphan bool, err error)
	VisitFederatedResources(visitFunc func(obj interface{}))
}

FederatedResourceAccessor provides a way to retrieve and visit logical federated resources (e.g. FederatedConfigMap)

func NewFederatedResourceAccessor

func NewFederatedResourceAccessor(
	controllerConfig *util.ControllerConfig,
	typeConfig typeconfig.Interface,
	fedNamespaceAPIResource *metav1.APIResource,
	client genericclient.Client,
	enqueueObj func(pkgruntime.Object),
	eventRecorder record.EventRecorder) (FederatedResourceAccessor, error)

type FederationSyncController

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

FederationSyncController synchronizes the state of a federated type to clusters that are members of the federation.

func (*FederationSyncController) Run

func (s *FederationSyncController) Run(stopChan <-chan struct{})
