Functions ¶
func BuildDefaultHTTPRoute ¶
BuildDefaultHTTPRoute builds a default route.
func GetDestinationCluster ¶
func GetDestinationCluster(destination *networking.Destination, service *model.Service, listenerPort int) string
GetDestinationCluster generate a cluster name for the route, or error if no cluster can be found. Called by translateRule to determine if
func TranslateRoutes ¶
func TranslateRoutes( virtualService model.Config, serviceIndex map[model.Hostname]*model.Service, port int, proxyLabels model.LabelsCollection, gatewayNames map[string]bool) ([]route.Route, error)
TranslateRoutes creates virtual host routes from the v1alpha3 config. The rule should be adapted to destination names (outbound clusters). Each rule is guarded by source labels.
This is called for each port to compute virtual hosts. Each VirtualService is tried, with a list of services that listen on the port. Error indicates the given virtualService can't be used on the port.
Types ¶
type GuardedHost ¶
type GuardedHost struct {
// Port is the capture port (e.g. service port)
Port int
// Services are the services matching the virtual host.
// The service host names need to be contextualized by the source.
Services []*model.Service
// Hosts is a list of alternative literal host names for the host.
Hosts []string
// Routes in the virtual host
Routes []route.Route
}
GuardedHost is a context-dependent virtual host entry with guarded routes.
func TranslateVirtualHosts ¶
func TranslateVirtualHosts( serviceConfigs []model.Config, services map[model.Hostname]*model.Service, proxyLabels model.LabelsCollection, gatewayNames map[string]bool) []GuardedHost
TranslateVirtualHosts creates the entire routing table for Istio v1alpha3 configs. Services are indexed by FQDN hostnames. Cluster domain is used to resolve short service names (e.g. "svc.cluster.local").
