Functions

func BasicKeyer

func BasicKeyer() func(metadata metav1.Object) types.NamespacedName

BasicKeyer returns a keyer retrieving the name and namespace from the object metadata.

func NamespacedKeyer

func NamespacedKeyer(namespace string) func(metadata metav1.Object) types.NamespacedName

NamespacedKeyer returns a keyer associated with the given namespace, retrieving the object name from its metadata.

func NewReflector

func NewReflector(name string, namespaced NamespacedReflectorFactoryFunc, fallback FallbackReflectorFactoryFunc, workers uint) manager.Reflector

NewReflector returns a new reflector to implement the reflection towards a remote clusters.

Types

type FallbackReflectorFactoryFunc

type FallbackReflectorFactoryFunc func(*options.ReflectorOpts) manager.FallbackReflector

FallbackReflectorFactoryFunc represents the function type to create a new FallbackReflector.

func WithoutFallback

func WithoutFallback() FallbackReflectorFactoryFunc

WithoutFallback returns a FallbackReflectorFactoryFunc which disables the fallback functionality.

type NamespacedReflector

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

NamespacedReflector implements the logic common to all namespaced reflectors.

func NewNamespacedReflector

func NewNamespacedReflector(opts *options.NamespacedOpts) NamespacedReflector

NewNamespacedReflector returns a new NamespacedReflector for the given namespaces.

func (*NamespacedReflector) DeleteRemote

func (gnr *NamespacedReflector) DeleteRemote(ctx context.Context, deleter ResourceDeleter, resource, name string, uid types.UID) error

DeleteRemote deletes the given remote resource from the cluster.

func (*NamespacedReflector) LocalNamespace

func (gnr *NamespacedReflector) LocalNamespace() string

LocalNamespace returns the local namespace associated with the reflector.

func (*NamespacedReflector) LocalRef

func (gnr *NamespacedReflector) LocalRef(name string) klog.ObjectRef

LocalRef returns the ObjectRef associated with the local namespace.

func (*NamespacedReflector) Ready

func (gnr *NamespacedReflector) Ready() bool

Ready returns whether the NamespacedReflector is completely initialized.

func (*NamespacedReflector) RemoteNamespace

func (gnr *NamespacedReflector) RemoteNamespace() string

RemoteNamespace returns the remote namespace associated with the reflector.

func (*NamespacedReflector) RemoteRef

func (gnr *NamespacedReflector) RemoteRef(name string) klog.ObjectRef

RemoteRef returns the ObjectRef associated with the remote namespace.

type NamespacedReflectorFactoryFunc

type NamespacedReflectorFactoryFunc func(*options.NamespacedOpts) manager.NamespacedReflector

NamespacedReflectorFactoryFunc represents the function type to create a new NamespacedReflector.

type ResourceDeleter

type ResourceDeleter interface {
	Delete(ctx context.Context, name string, opts metav1.DeleteOptions) error
}

ResourceDeleter know how to delete a Kubernetes object with the given name.
