Functions

func InitFlags

func InitFlags(flagset *pflag.FlagSet)

InitFlags is for explicitly initializing the flags.

Types

type Controller

type Controller struct {
	controller.DefaultController
	// contains filtered or unexported fields
}

Controller is the controller implementation for ReplicaSet resources

func NewController

func NewController(
	kubeclientset kubernetes.Interface,
	carbonclientset clientset.Interface,
	shardGroupInformer informers.ShardGroupInformer,
	rollingSetInformer informers.RollingSetInformer,
	workerInformer informers.WorkerNodeInformer) *Controller

NewController returns a new rollingset controller

func (*Controller) DeleteSubObj

func (c *Controller) DeleteSubObj(namespace, key string) error

DeleteSubObj is used for controller to handle gc

func (*Controller) GetObj

func (c *Controller) GetObj(namespace, key string) (interface{}, error)

GetObj for controller manager

func (*Controller) Sync

func (c *Controller) Sync(key string) error

Sync compares the actual state with the desired, and attempts to converge the two. It then updates the spec of the RollingSet resource with the current spec of the resource.

func (*Controller) WaitForCacheSync

func (c *Controller) WaitForCacheSync(stopCh <-chan struct{}) bool

WaitForCacheSync wait informers synced
