Constants

const (
	// GenerationKey holds the generation of the parent KIngress resource that the HTTPProxy's
	// spec is derived from.  This is updated along with the spec of child HTTPProxy resources
	// and then used to cleanup stale HTTPProxy resources owned by the parent.
	GenerationKey = "contour.networking.knative.dev/generation"
	// ParentKey hold the name of the parent KIngress resource, since OwnerReferences cannot
	// be used in filter expressions.
	ParentKey = "contour.networking.knative.dev/parent"
	// DomainHashKey contains the hash of the fqdn for which this HTTPProxy exists.  We use
	// the hash in place of the actual fqdn because there is a limit on the length of label
	// values.
	DomainHashKey = "contour.networking.knative.dev/domainHash"

	// ClassKey contains the name of the contour class annotation used to select the
	// Contour instance that handles a given HTTP Proxy.
	ClassKey = "projectcontour.io/ingress.class"

	// EndpointsProbeKey is placed on child Ingress resources to bypass Endpoint probing,
	// since the child ingress exists to be said endpoint probe.
	EndpointsProbeKey = "contour.networking.knative.dev/endpointsProbe"
)

These are the label keys that are applied to HTTP proxy resources to facilitate reconciliation.

const (
	// If this annotation is set in ksvc/ingress, it is used as the ExternalService name in the
	// generated HttpProxy
	ExtensionServiceKey          = "contour.networking.knative.dev/extension-service"
	ExtensionServiceNamespaceKey = "contour.networking.knative.dev/extension-service-namespace"
)

These are the annotations which are optionally set in ksvc/ingress

Functions

func MakeEndpointProbeIngress

func MakeEndpointProbeIngress(ctx context.Context, ing *v1alpha1.Ingress, previousState []*v1.HTTPProxy) *v1alpha1.Ingress

MakeEndpointProbeIngress creates a new child kingress resource with a bogus hostname per referenced service, which we will probe to ensure each service has been warmed in Envoy's EDS before changing any of the active RDS programming to reference those endpoints.

func MakeHTTPProxies

func MakeHTTPProxies(ctx context.Context, ing *v1alpha1.Ingress, serviceToProtocol map[string]string) []*v1.HTTPProxy

func ServiceNames

func ServiceNames(ctx context.Context, ing *v1alpha1.Ingress) map[string]ServiceInfo

Types

type ServiceInfo

type ServiceInfo struct {
	Port            intstr.IntOrString
	RawVisibilities sets.String
	// If the Host header sent to this service needs to be rewritten,
	// then track that so we can send it for probing.
	RewriteHost string

	// TODO(https://github.com/knative-sandbox/net-certmanager/issues/44): Remove this.
	HasPath bool
}

func (*ServiceInfo) Visibilities

func (si *ServiceInfo) Visibilities() (vis []v1alpha1.IngressVisibility)
