Functions

func GetConfigMapData

func GetConfigMapData(ctx context.Context, c client.Client, configMapName, keyName string) (map[string]interface{}, error)

GetConfigMapData gets specified data in given ConfigMap from kube-system namespace

func GetDNSClass

func GetDNSClass(ctx context.Context, c client.Client, podNamespace string) (configv1alpha1.DNSClass, error)

GetDNSClass finds the DNSClass for the pod object with its namespace

func UpdateAnnotation

func UpdateAnnotation(obj client.Object, key, value string)

UpdateAnnotation updates or adds an annotation to a Kubernetes object

Types

type DnsClassPredicate

type DnsClassPredicate struct {
	predicate.Funcs
}

DnsClassPredicate is a predicate for DNSClass objects

func (*DnsClassPredicate) Create

func (*DnsClassPredicate) Create(e event.CreateEvent) bool

Create checks if a DNSClass object is marked as reconciled

func (*DnsClassPredicate) Delete

func (*DnsClassPredicate) Delete(e event.DeleteEvent) bool

Delete always returns false for DNSClass deletion events

func (*DnsClassPredicate) Generic

func (*DnsClassPredicate) Generic(e event.GenericEvent) bool

Generic always returns false for generic events

func (*DnsClassPredicate) Update

func (*DnsClassPredicate) Update(e event.UpdateEvent) bool

Update checks if a DNSClass object is updated

type Workload

type Workload struct {
	Name      string
	Namespace string
	Kind      string
}

Workload used to define objects
