Functions

func DefaultNamespace added in v1.7.0 

func DefaultNamespace(ns string) func(name *types.NamespacedName)

DefaultNamespace can be used with NamespacedNameFrom to set the default namespace for a resource name that may not be qualified by a namespace.

func InitLogging added in v1.9.0 

func InitLogging(options ...LogOption)

InitLogging initializes the Kubernetes client-go logging subsystem.

func IsObjectEqual added in v1.25.0 

func IsObjectEqual(old, new client.Object) (bool, error)

IsObjectEqual checks if objects received during update are equal.

Make an attempt to avoid comparing full objects since it can be very CPU intensive. Prefer comparing Generation when only interested in spec changes.

func KindOf added in v1.1.0 

func KindOf(obj any) string

KindOf returns the kind string for the given Kubernetes object.

The API machinery doesn't populate the metav1.TypeMeta field for objects, so we have to use a type assertion to detect kinds that we care about.

func NamespacedNameFrom added in v1.7.0 

func NamespacedNameFrom(nameStr string, opts ...func(*types.NamespacedName)) types.NamespacedName

NamespacedNameFrom parses a resource name string into a fully qualified NamespacedName.

func NamespacedNameOf added in v1.7.0 

func NamespacedNameOf(obj metav1.Object) types.NamespacedName

NamespacedNameOf returns the NamespacedName of any given Kubernetes object.

func NewContourScheme added in v1.10.0 

func NewContourScheme() (*runtime.Scheme, error)

NewContourScheme returns a scheme that includes all the API types that Contour supports as well as the core Kubernetes API types from the default scheme.

func NewCoreClient added in v1.20.0 

func NewCoreClient(kubeconfig string, inCluster bool) (*kubernetes.Clientset, error)

NewCoreClient returns a new Kubernetes core API client using the supplied kubeconfig path, or the cluster environment variables if inCluster is true.

func NewNamespaceFilter added in v1.10.0 

func NewNamespaceFilter(
	namespaces []string,
	next cache.ResourceEventHandler,
) cache.ResourceEventHandler

NewNamespaceFilter returns a cache.ResourceEventHandler that accepts only objects whose namespaces are included in the given slice of namespaces. Objects with matching namespaces are passed to the next handler.

func NewRestConfig added in v1.20.0 

func NewRestConfig(kubeconfig string, inCluster bool, opts ...func(*rest.Config)) (*rest.Config, error)

NewRestConfig returns a *rest.Config for the supplied kubeconfig path, or the cluster environment variables if inCluster is true.

func OptSetBurst added in v1.24.0 

func OptSetBurst(burst int) func(*rest.Config)

func TLSCertAnnotationNamespace added in v1.20.0 

func TLSCertAnnotationNamespace(ing *networking_v1.Ingress) func(name *types.NamespacedName)

TLSCertAnnotationNamespace can be used with NamespacedNameFrom to set the secret namespace from the "projectcontour.io/tls-cert-namespace" annotation

func VersionOf added in v1.8.0 

func VersionOf(obj any) string

VersionOf returns the GroupVersion string for the given Kubernetes object.

Types

type LogOption added in v1.9.0

type ServiceStatusLoadBalancerWatcher struct {
	ServiceName string
	LBStatus    chan v1.LoadBalancerStatus
	Log         logrus.FieldLogger
}

ServiceStatusLoadBalancerWatcher implements ResourceEventHandler and watches for changes to the status.loadbalancer field Note that we specifically *don't* inspect inside the struct, as sending empty values is desirable to clear the status.

func (*ServiceStatusLoadBalancerWatcher) OnAdd added in v1.4.0 

func (s *ServiceStatusLoadBalancerWatcher) OnAdd(obj any, isInInitialList bool)

func (*ServiceStatusLoadBalancerWatcher) OnDelete added in v1.4.0 

func (s *ServiceStatusLoadBalancerWatcher) OnDelete(obj any)

func (*ServiceStatusLoadBalancerWatcher) OnUpdate added in v1.4.0 

func (s *ServiceStatusLoadBalancerWatcher) OnUpdate(oldObj, newObj any)

type StatusAddressUpdater added in v1.5.0 

type StatusAddressUpdater struct {

	GatewayRef            *types.NamespacedName
	StatusUpdater         StatusUpdater
	// contains filtered or unexported fields
}

StatusAddressUpdater observes informer OnAdd and OnUpdate events and updates the ingress.status.loadBalancer field on all Ingress objects that match the ingress class (if used). Note that this is intended to handle updating the status.loadBalancer struct only, not more general status updates. That's a job for the StatusUpdater.

func (*StatusAddressUpdater) OnAdd added in v1.5.0 

func (s *StatusAddressUpdater) OnAdd(obj any, isInInitialList bool)

func (s *StatusAddressUpdater) OnDelete(obj any)

func (*StatusAddressUpdater) OnUpdate added in v1.5.0 

func (s *StatusAddressUpdater) OnUpdate(oldObj, newObj any)

func (*StatusAddressUpdater) Set added in v1.10.0 

func (s *StatusAddressUpdater) Set(status v1.LoadBalancerStatus)

Set updates the LBStatus field.

type StatusMetrics added in v1.26.0 

type StatusMetrics interface {
	SetStatusUpdateTotal(kind string)
	SetStatusUpdateSuccess(kind string)
	SetStatusUpdateNoop(kind string)

	Resource       client.Object
	Mutator        StatusMutator
