}

ControllerContext holds the state needed for the execution of the controller.

func NewControllerContext

func NewControllerContext(
	kubeConfig *rest.Config,
	kubeClient kubernetes.Interface,
	backendConfigClient backendconfigclient.Interface,
	frontendConfigClient frontendconfigclient.Interface,
	svcnegClient svcnegclient.Interface,

	saClient serviceattachmentclient.Interface,
	cloud *gce.Cloud,
	clusterNamer *namer.Namer,
	kubeSystemUID types.UID,
	config ControllerContextConfig) *ControllerContext

NewControllerContext returns a new shared set of informers.

func (*ControllerContext) AddHealthCheck

func (ctx *ControllerContext) AddHealthCheck(id string, hc func() error)

AddHealthCheck registers function to be called for healthchecking.

func (*ControllerContext) BackendConfigs

func (ctx *ControllerContext) BackendConfigs() *typed.BackendConfigStore

BackendConfigs returns the store of BackendConfigs.

func (*ControllerContext) FrontendConfigs

func (ctx *ControllerContext) FrontendConfigs() *typed.FrontendConfigStore

FrontendConfigs returns the store of FrontendConfigs.

func (*ControllerContext) HasSynced

func (ctx *ControllerContext) HasSynced() bool

HasSynced returns true if all relevant informers has been synced.

func (*ControllerContext) HealthCheck

func (ctx *ControllerContext) HealthCheck() HealthCheckResults

HealthCheck runs all registered healthcheck functions.

func (*ControllerContext) Ingresses

func (ctx *ControllerContext) Ingresses() *typed.IngressStore

Ingresses returns the store of Ingresses.

func (*ControllerContext) Init

func (ctx *ControllerContext) Init()

Init inits the Context, so that we can defers some config until the main thread enter actually get the leader lock.

func (*ControllerContext) Recorder

func (ctx *ControllerContext) Recorder(ns string) record.EventRecorder

Recorder return the event recorder for the given namespace.

func (*ControllerContext) Services

func (ctx *ControllerContext) Services() *typed.ServiceStore

Services returns the store of Services.

func (*ControllerContext) Start

func (ctx *ControllerContext) Start(stopCh chan struct{})

Start all of the informers.

type ControllerContextConfig

type ControllerContextConfig struct {
	Namespace    string
	ResyncPeriod time.Duration
	NumL4Workers int
	// DefaultBackendSvcPortID is the ServicePort for the system default backend.
	DefaultBackendSvcPort utils.ServicePort
	HealthCheckPath       string
	FrontendConfigEnabled bool
	EnableASMConfigMap    bool
	ASMConfigMapNamespace string
	ASMConfigMapName      string
}

ControllerContextConfig encapsulates some settings that are tunable via command line flags.

type HealthCheckResults

type HealthCheckResults map[string]error

HealthCheckResults contains a mapping of component -> health check results.
