ListMonitoredNamespaces returns all namespaces that the mesh is monitoring.

func (Client) ListPods added in v0.4.1 

func (c Client) ListPods() []*corev1.Pod

ListPods returns a list of pods part of the mesh Kubecontroller does not currently segment pod notifications, hence it receives notifications for all k8s Pods.

func (Client) ListServices added in v0.4.0 

func (c Client) ListServices() []*corev1.Service

ListServices returns a list of services that are part of monitored namespaces

type Controller added in v0.4.0 

type Controller interface {
	// ListServices returns a list of all (monitored-namespace filtered) services in the mesh
	ListServices() []*corev1.Service

	// Returns a corev1 Service representation if the MeshService exists in cache, otherwise nil
	GetService(svc service.MeshService) *corev1.Service

	// IsMonitoredNamespace returns whether a namespace with the given name is being monitored
	// by the mesh
	IsMonitoredNamespace(string) bool

	// ListMonitoredNamespaces returns the namespaces monitored by the mesh
	ListMonitoredNamespaces() ([]string, error)

	// GetNamespace returns k8s namespace present in cache
	GetNamespace(ns string) *corev1.Namespace

	// Returns the announcement channel for a certain Informer ID
	GetAnnouncementsChannel(informerID InformerKey) <-chan interface{}

	// ListPods returns a list of pods part of the mesh

}

Controller is the controller interface for K8s services

func NewKubernetesController added in v0.4.0 

func NewKubernetesController(kubeClient kubernetes.Interface, meshName string, stop chan struct{}) (Controller, error)

NewKubernetesController returns a new kubernetes.Controller which means to provide access to locally-cached k8s resources

type Event 

type Event struct {
	Type  EventType
	Value interface{}
}

Event is the combined type and actual object we received from Kubernetes

type EventType 

type EventType int

EventType is the type of event we have received from Kubernetes
