Functions

func RegisterMetricAndTrackRateLimiterUsage

func RegisterMetricAndTrackRateLimiterUsage(ownerName string, _ flowcontrol.RateLimiter) error

RegisterMetricAndTrackRateLimiterUsage registers a metric ownerName_rate_limiter_use in prometheus to track how much used rateLimiter is and starts a goroutine that updates this metric every updatePeriod

Types

type Controller

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

Controller is the controller that manages node ipam state.

func NewNodeIpamController

func NewNodeIpamController(
	nodeInformer coreinformers.NodeInformer,
	cloud cloudprovider.Interface,
	kubeClient clientset.Interface,
	clusterCIDRs []*net.IPNet,
	serviceCIDR *net.IPNet,
	secondaryServiceCIDR *net.IPNet,
	nodeCIDRMaskSizes []int,
	allocatorType ipam.CIDRAllocatorType) (*Controller, error)

NewNodeIpamController returns a new node IP Address Management controller to sync instances from cloudprovider. This method returns an error if it is unable to initialize the CIDR bitmap with podCIDRs it has already allocated to nodes. Since we don't allow podCIDR changes currently, this should be handled as a fatal error.

func (*Controller) Run

func (nc *Controller) Run(stopCh <-chan struct{})

Run starts an asynchronous loop that monitors the status of cluster nodes.
