Functions

func SyncMachineAnnotations

func SyncMachineAnnotations(
	machine *v1alpha1.Machine,
	node *v1.Node,
	lastAppliedAnnotations map[string]string,
) bool

SyncMachineAnnotations syncs the annotations of the machine with node-objects. It returns true if update is needed else false.

func SyncMachineLabels

func SyncMachineLabels(
	machine *v1alpha1.Machine,
	node *v1.Node,
	lastAppliedLabels map[string]string,
) bool

SyncMachineLabels syncs the labels of the machine with node-objects. It returns true if update is needed else false.

func SyncMachineTaints

func SyncMachineTaints(
	machine *v1alpha1.Machine,
	node *v1.Node,
	lastAppliedTaints []v1.Taint,
) bool

SyncMachineTaints syncs the taints of the machine with node-objects. It returns true if update is needed else false.

Types

type Controller

type Controller interface {
	// Run runs the controller until the given stop channel can be read from.
	// workers specifies the number of goroutines, per resource, processing work
	// from the resource workqueues
	Run(workers int, stopCh <-chan struct{})
}

Controller describes a controller for
