Types

type Controller

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

Controller is the controller that manages node ipam state.

func NewNodeIpamController

func NewNodeIpamController(
	ctx context.Context,
	nodeInformer coreinformers.NodeInformer,
	clusterCIDRInformer networkinginformers.ClusterCIDRInformer,
	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(ctx context.Context)

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

func (*Controller) RunWithMetrics

func (nc *Controller) RunWithMetrics(ctx context.Context, controllerManagerMetrics *controllersmetrics.ControllerManagerMetrics)

RunWithMetrics is a wrapper for Run that also tracks starting and stopping of the nodeipam controller with additional metric
