MetricRequeueServiceCount is the number of times a particular service has been requeued.

var MetricSyncServiceCount = prometheus.NewCounterVec(prometheus.CounterOpts{
	Namespace: "",
	Subsystem: "",
	Name:      "sync_service_total",
	Help:      "A metric that captures the number of times a service is synced"},
	[]string{
		"name",
	},
)

MetricSyncServiceCount is the number of times a particular service has been synced.

	Help:      "The latency of syncing a service",

)

MetricSyncServiceLatency is the time taken to sync a service with the OVN load balancers.

Types

type Controller

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

Controller manages selector-based service endpoints.

func NewController

func NewController(client clientset.Interface,
	serviceInformer coreinformers.ServiceInformer,
	endpointSliceInformer discoveryinformers.EndpointSliceInformer,
	loadBalancer LoadBalancer,
) *Controller

NewController returns a new *Controller.

func (*Controller) Run

func (c *Controller) Run(workers int, stopCh <-chan struct{}) error

Run will not return until stopCh is closed. workers determines how many endpoints will be handled in parallel.

type LB

type LB struct {
	Frontend VirtualIP
	Backend  []string
}

LB represents a LoadBalancer object with one frontend [IP:Port] and Protocol and several backends as IP:Port

type LoadBalancer

type LoadBalancer interface {
	Apply(lb LB) error
	Remove(lb LB) error
}

LoadBalancer

type VirtualIP

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