Types ¶
type Builder ¶
type Builder struct { // IngressRouteRootNamespaces specifies the namespaces where root // IngressRoutes can be defined. If empty, roots can be defined in any // namespace. IngressRouteRootNamespaces []string // contains filtered or unexported fields }
A Builder holds Kubernetes objects and associated configuration and produces DAG values.
type DAG ¶
type DAG struct {
// contains filtered or unexported fields
}
A DAG represents a directed acylic graph of objects representing the relationship between Kubernetes Ingress objects, the backend Services, and Secret objects. The DAG models these relationships as Roots and Vertices.
type Route ¶
type Route struct { Object interface{} // one of Ingress or IngressRoute // Should this route generate a 301 upgrade if accessed // over HTTP? HTTPSUpgrade bool // Is this a websocket route? // TODO(dfc) this should go on the service Websocket bool // A timeout applied to requests on this route. // A timeout of zero implies "use envoy's default" // A timeout of -1 represents "infinity" // TODO(dfc) should this move to service? Timeout time.Duration // contains filtered or unexported fields }
type Secret ¶
type Secret struct {
// contains filtered or unexported fields
}
Secret represents a K8s Secret for TLS usage as a DAG Vertex. A Secret is a leaf in the DAG.
type SecureVirtualHost ¶
type SecureVirtualHost struct { // Port is the port that the VirtualHost will listen on. // Expected values are 80 and 443, but others are possible // if the VirtualHost is generated inside Contour. Port int // TLS minimum protocol version. Defaults to auth.TlsParameters_TLS_AUTO MinProtoVersion auth.TlsParameters_TlsProtocol // contains filtered or unexported fields }
A SecureVirtualHost represents a HTTP host protected by TLS.
func (*SecureVirtualHost) Data ¶
func (s *SecureVirtualHost) Data() map[string][]byte
func (*SecureVirtualHost) FQDN ¶
func (s *SecureVirtualHost) FQDN() string
func (*SecureVirtualHost) Visit ¶
func (s *SecureVirtualHost) Visit(f func(Vertex))
type Service ¶
type Service struct { Object *v1.Service *v1.ServicePort Weight int // Protocol is the layer 7 protocol of this service Protocol string HealthCheck *ingressroutev1.HealthCheck LoadBalancerStrategy string // Max connections is maximum number of connections // that Envoy will make to the upstream cluster. MaxConnections int // MaxPendingRequests is maximum number of pending // requests that Envoy will allow to the upstream cluster. MaxPendingRequests int // MaxRequests is the maximum number of parallel requests that // Envoy will make to the upstream cluster. MaxRequests int // MaxRetries is the maximum number of parallel retries that // Envoy will allow to the upstream cluster. MaxRetries int }
Service represents a K8s Sevice as a DAG vertex. A Service is a leaf in the DAG.
type Status ¶
type Status struct { Object *ingressroutev1.IngressRoute Status string Description string Vhost string // SAS: Support `aliases` once merged }
Status contains the status for an IngressRoute (valid / invalid / orphan, etc)
type VirtualHost ¶
type VirtualHost struct { // Port is the port that the VirtualHost will listen on. // Expected values are 80 and 443, but others are possible // if the VirtualHost is generated inside Contour. Port int // contains filtered or unexported fields }
A VirtualHost represents an insecure HTTP host.
func (*VirtualHost) FQDN ¶
func (v *VirtualHost) FQDN() string
func (*VirtualHost) Visit ¶
func (v *VirtualHost) Visit(f func(Vertex))
