Functions

func CompositeReconcilerOptions

func CompositeReconcilerOptions(co controller.Options, d *v1.CompositeResourceDefinition, c client.Client, l logging.Logger, e event.Recorder) []composite.ReconcilerOption

CompositeReconcilerOptions builds the options for a composite resource reconciler. The options vary based on the supplied feature flags.

func Setup

func Setup(mgr ctrl.Manager, o controller.Options) error

Setup adds a controller that reconciles CompositeResourceDefinitions by defining a composite resource and starting a controller to reconcile it.

Types

type CRDRenderFn

type CRDRenderFn func(d *v1.CompositeResourceDefinition) (*extv1.CustomResourceDefinition, error)

A CRDRenderFn renders a CompositeResourceDefinition's corresponding CustomResourceDefinition.

func (CRDRenderFn) Render

func (fn CRDRenderFn) Render(d *v1.CompositeResourceDefinition) (*extv1.CustomResourceDefinition, error)

Render the supplied CompositeResourceDefinition's corresponding CustomResourceDefinition.

type CRDRenderer

type CRDRenderer interface {
	Render(d *v1.CompositeResourceDefinition) (*extv1.CustomResourceDefinition, error)
}

A CRDRenderer renders a CompositeResourceDefinition's corresponding CustomResourceDefinition.

type ControllerEngine

type ControllerEngine interface {
	IsRunning(name string) bool
	Start(name string, o kcontroller.Options, w ...controller.Watch) error
	Stop(name string)
	Err(name string) error
}

A ControllerEngine can start and stop Kubernetes controllers on demand.

type Reconciler

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

A Reconciler reconciles CompositeResourceDefinitions.

func NewReconciler

func NewReconciler(mgr manager.Manager, opts ...ReconcilerOption) *Reconciler

NewReconciler returns a Reconciler of CompositeResourceDefinitions.

func (*Reconciler) Reconcile

func (r *Reconciler) Reconcile(ctx context.Context, req reconcile.Request) (reconcile.Result, error)

Reconcile a CompositeResourceDefinition by defining a new kind of composite resource and starting a controller to reconcile it.

type ReconcilerOption

type ReconcilerOption func(*Reconciler)

ReconcilerOption is used to configure the Reconciler.

func WithCRDRenderer

func WithCRDRenderer(c CRDRenderer) ReconcilerOption

WithCRDRenderer specifies how the Reconciler should render an CompositeResourceDefinition's corresponding CustomResourceDefinition.

func WithClientApplicator

func WithClientApplicator(ca resource.ClientApplicator) ReconcilerOption

WithClientApplicator specifies how the Reconciler should interact with the Kubernetes API.

func WithControllerEngine

func WithControllerEngine(c ControllerEngine) ReconcilerOption

WithControllerEngine specifies how the Reconciler should manage the lifecycles of composite controllers.

func WithFinalizer

func WithFinalizer(f resource.Finalizer) ReconcilerOption

WithFinalizer specifies how the Reconciler should finalize CompositeResourceDefinitions.

func WithLogger

func WithLogger(log logging.Logger) ReconcilerOption

WithLogger specifies how the Reconciler should log messages.

func WithOptions

func WithOptions(o controller.Options) ReconcilerOption

WithOptions lets the Reconciler know which options to pass to new composite resource controllers.

func WithRecorder

func WithRecorder(er event.Recorder) ReconcilerOption

WithRecorder specifies how the Reconciler should record Kubernetes events.
