Functions

func CRDExists

func CRDExists(restMapper meta.RESTMapper, gvr schema.GroupVersionResource) bool

CRDExists returns false if CRD does not exist.

func GeneratePredicateFuncsForIngressClassFilter

func GeneratePredicateFuncsForIngressClassFilter(name string) predicate.Funcs

GeneratePredicateFuncsForIngressClassFilter builds a controller-runtime reconciliation predicate function which filters out objects which have their ingress class set to the a value other than the controller class.

func IsDefaultIngressClass

func IsDefaultIngressClass(obj client.Object) bool

IsDefaultIngressClass returns whether an IngressClass is the default IngressClass.

func IsIngressClassEmpty

func IsIngressClassEmpty(obj client.Object) bool

IsIngressClassEmpty returns true if an object has no ingress class information or false otherwise.

func MatchesIngressClass

func MatchesIngressClass(obj client.Object, controllerIngressClass string, isDefault bool) bool

MatchesIngressClass indicates whether or not an object belongs to a given ingress class.

func UpdateLoadBalancerIngress

func UpdateLoadBalancerIngress(
	ingress client.Object,
	newAddresses []netv1.IngressLoadBalancerIngress,
) (updateNeeded bool, err error)

UpdateLoadBalancerIngress updates any supported Ingress object with new []netv1.IngressLoadBalancerIngress in a backward-compatible fashion if needed. Update does not happen in case there are no changes detected.
