Functions

func HandlerForNode

func HandlerForNode(
	cnc *CloudNodeController,
	ninformer coreinformers.NodeInformer,
)

func PatchNode

func PatchNode(
	kdm kubernetes.Interface,
	origined, patched *v1.Node,
) (*v1.Node, error)

Types

type CloudInstance

type CloudInstance interface {
	// SetInstanceTags set instance tags for instance id
	SetInstanceTags(insid string, tags map[string]string) error

	// ListInstances list instance by given ids.
	ListInstances(ids []string) (map[string]*CloudNodeAttribute, error)
}

CloudInstance is an interface to interact with cloud api

type CloudNodeAttribute

type CloudNodeAttribute struct {
	InstanceID   string
	Addresses    []v1.NodeAddress
	InstanceType string
}

CloudNodeAttribute node attribute from cloud instance

type CloudNodeController

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

func NewCloudNodeController

func NewCloudNodeController(
	ninformer coreinformers.NodeInformer,
	kubeClient clientset.Interface,
	cloud cloudprovider.Interface,
	nodeMonitorPeriod time.Duration,
	nodeStatusUpdateFrequency time.Duration,
) *CloudNodeController

NewCloudNodeController creates a CloudNodeController object

func (*CloudNodeController) AddCloudNode

func (cnc *CloudNodeController) AddCloudNode(node *v1.Node) error

func (*CloudNodeController) Run

func (cnc *CloudNodeController) Run(stopCh <-chan struct{})

This controller deletes a node if kubelet is not reporting and the node is gone from the cloud provider.
