Types

type Controller

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

Controller is the controller implementation for machine resources

func NewMachineController

func NewMachineController(
	kubeClient kubernetes.Interface,
	machineClient machineclientset.Interface,
	nodeInformer cache.SharedIndexInformer,
	nodeLister listerscorev1.NodeLister,
	machineInformer cache.SharedIndexInformer,
	machineLister machinelistersv1alpha1.MachineLister,
	secretSystemNsLister listerscorev1.SecretLister,
	clusterDNSIPs []net.IP,
	metrics *MetricsCollection,
	kubeconfigProvider KubeconfigProvider,
	name string) *Controller

NewMachineController returns a new machine controller

func (*Controller) ReadinessChecks

func (c *Controller) ReadinessChecks() map[string]healthcheck.Check

func (*Controller) Run

func (c *Controller) Run(threadiness int, stopCh <-chan struct{}) error

Run starts the control loop

type KubeconfigProvider

type KubeconfigProvider interface {
	GetKubeconfig() (*clientcmdapi.Config, error)
}

type MetricsCollection

type MetricsCollection struct {
	Machines            prometheus.Gauge
	Nodes               prometheus.Gauge
	Workers             prometheus.Gauge
	Errors              prometheus.Counter
	ControllerOperation *prometheus.HistogramVec
	NodeJoinDuration    *prometheus.HistogramVec
}

MetricsCollection is a struct of all metrics used in this controller.

func NewMachineControllerMetrics

func NewMachineControllerMetrics() *MetricsCollection

NewMachineControllerMetrics creates new MachineControllerMetrics with default values initialized, so metrics always show up.
