Documentation

Overview

Package inject defines interfaces and functions for propagating dependencies from a ControllerManager to the components registered with it. Dependencies are propagated to Reconciler, Source, EventHandler and Predicate objects which implement the Injectable interfaces.

Functions

func APIReaderInto

func APIReaderInto(reader client.Reader, i interface{}) (bool, error)

APIReaderInto will set APIReader on i and return the result if it implements APIReaderInto. Returns false if i does not implement APIReader

func CacheInto

func CacheInto(c cache.Cache, i interface{}) (bool, error)

CacheInto will set informers on i and return the result if it implements Cache. Returns // false if i does not implement Cache.

func ClientInto

func ClientInto(client client.Client, i interface{}) (bool, error)

ClientInto will set client on i and return the result if it implements Client. Returns false if i does not implement Client.

func ConfigInto

func ConfigInto(config *rest.Config, i interface{}) (bool, error)

ConfigInto will set config on i and return the result if it implements Config. Returns // false if i does not implement Config.

func InjectorInto

func InjectorInto(f Func, i interface{}) (bool, error)

InjectorInto will set f and return the result on i if it implements Injector. Returns false if i does not implement Injector.

func LoggerInto

func LoggerInto(l logr.Logger, i interface{}) (bool, error)

LoggerInto will set the logger on the given object if it implements inject.Logger, returning true if a InjectLogger was called, and false otherwise.

func MapperInto

func MapperInto(mapper meta.RESTMapper, i interface{}) (bool, error)

MapperInto will set the rest mapper on i and return the result if it implements Mapper. Returns false if i does not implement Mapper.

func SchemeInto

func SchemeInto(scheme *runtime.Scheme, i interface{}) (bool, error)

SchemeInto will set scheme and return the result on i if it implements Scheme. Returns false if i does not implement Scheme.

func StopChannelInto

func StopChannelInto(stop <-chan struct{}, i interface{}) (bool, error)

StopChannelInto will set stop channel on i and return the result if it implements Stoppable. Returns false if i does not implement Stoppable.

Types

type APIReader

type APIReader interface {
	InjectAPIReader(client.Reader) error
}

APIReader is used by the Manager to inject the APIReader into necessary types.

type Cache

type Cache interface {
	InjectCache(cache cache.Cache) error
}

Cache is used by the ControllerManager to inject Cache into Sources, EventHandlers, Predicates, and Reconciles

type Client

type Client interface {
	InjectClient(client.Client) error
}

Client is used by the ControllerManager to inject client into Sources, EventHandlers, Predicates, and Reconciles

type Config

type Config interface {
	InjectConfig(*rest.Config) error
}

Config is used by the ControllerManager to inject Config into Sources, EventHandlers, Predicates, and Reconciles

type Func

type Func func(i interface{}) error

Func injects dependencies into i.

type Injector

type Injector interface {
	InjectFunc(f Func) error
}

Injector is used by the ControllerManager to inject Func into Controllers

type Logger

type Logger interface {
	InjectLogger(l logr.Logger) error
}

Logger is used to inject Loggers into components that need them and don't otherwise have opinions.

type Mapper

type Mapper interface {
	InjectMapper(meta.RESTMapper) error
}

Mapper is used to inject the rest mapper to components that may need it

type Scheme

type Scheme interface {
	InjectScheme(scheme *runtime.Scheme) error
}

Scheme is used by the ControllerManager to inject Scheme into Sources, EventHandlers, Predicates, and Reconciles

type Stoppable

type Stoppable interface {
	InjectStopChannel(<-chan struct{}) error
}

Stoppable is used by the ControllerManager to inject stop channel into Sources, EventHandlers, Predicates, and Reconciles.
