Functions

func ComputeHash

func ComputeHash(ing *v1alpha1.Ingress) ([sha256.Size]byte, error)

ComputeHash computes a hash of the Ingress Spec, Namespace and Name

func ExpandedHosts

func ExpandedHosts(hosts sets.String) sets.String

ExpandedHosts sets up hosts for the short-names for cluster DNS names.

func HostsPerVisibility

func HostsPerVisibility(ing *v1alpha1.Ingress, visibilityToKey map[v1alpha1.IngressVisibility]sets.String) map[string]sets.String

HostsPerVisibility takes an Ingress and a map from visibility levels to a set of string keys, it then returns a map from that key space to the hosts under that visibility.

func InsertProbe

func InsertProbe(ing *v1alpha1.Ingress) (string, error)

InsertProbe adds a AppendHeader rule so that any request going through a Gateway is tagged with the version of the Ingress currently deployed on the Gateway. TODO: move this to github.com/knative/networking — currently it is used by downstream consumers, see: https://github.com/knative/serving/issues/7482.
