Functions

func AddToManager 

func AddToManager(_ context.Context, mgr manager.Manager) error

AddToManager adds a controller with the default AddOptions to the given manager.

func AddToManagerWithOptions 

func AddToManagerWithOptions(mgr manager.Manager, options AddOptions) error

AddToManagerWithOptions adds a controller with the given AddOptions to the given manager.

func NewActuator 

func NewActuator(client client.Client, namespace string, syncPeriod time.Duration, logger logr.Logger) controller.Actuator

NewActuator creates a new Actuator.

func NewPredicate added in v0.9.0 

func NewPredicate(nodeCache utils.ExpiringCache, logger logr.Logger) predicate.Predicate

NewPredicate creates a new predicate that filters only relevant node events, such as creating or deleting a node, updating the deletion timestamp of a node, or updating the ready condition or unreachable taint of a node.

Types

type AddOptions 

type AddOptions struct {
	// Controller are the controller.Options.
	Controller controller.Options
	// Client is the Kubernetes client for the control cluster.
	Client client.Client
	// Namespace is the namespace for custom resources in the control cluster.
	Namespace string
	// Manager is the control cluster manager.
	Manager manager.Manager
	// Config is the configuration for the Azure failed virtual machine remedy.
	Config config.AzureFailedVMRemedyConfiguration
}

AddOptions are options to apply when adding a controller to a manager.

type Projection added in v0.9.0 

type Projection struct {
	DeletionTimestamp     *metav1.Time
	NotReadyOrUnreachable bool
}

Projection captures only the essential properties of a node that is being cached. By using projections, we prevent the cache from getting too big for clusters with large number of nodes.

func NewProjection added in v0.9.0 

func NewProjection(node *corev1.Node) *Projection

NewProjection creates a new Projection from the given node.
