Functions

func FilterClusterOperator

func FilterClusterOperator(name string) predicate.Predicate

FilterClusterOperator filters cluster operator requests to just the one with the name provided.

func FilterControlPlaneMachineSet

func FilterControlPlaneMachineSet(controlPlaneMachineSetName, namespace string) predicate.Predicate

FilterControlPlaneMachineSet filters control plane machine set requests to just the singleton within the namespace provided.

func FilterControlPlaneMachines

func FilterControlPlaneMachines(namespace string) predicate.Predicate

FilterControlPlaneMachines filters machine requests to just the machines that present as control plane machines, i.e. they are labelled with the correct labels to identify them as control plane machines.

func FilterControlPlaneNodes

func FilterControlPlaneNodes() predicate.Predicate

FilterControlPlaneNodes filters nodes requests to just the nodes that present as control plane nodes and that have had a transition in the NodeReady condition.

func FilterInfrastructure

func FilterInfrastructure(infraName string) predicate.Predicate
