Functions ¶
func ServicePort ¶ added in v0.6.0
func ServicePort(proto ProtocolType) int
ServicePort chooses the service (load balancer) port for the public service.
func ServicePortName ¶ added in v0.6.0
func ServicePortName(proto ProtocolType) string
ServicePortName returns the port for the app level protocol.
Types ¶
type ProtocolType ¶ added in v0.5.0
type ProtocolType string
ProtocolType is an enumeration of the supported application-layer protocols See also: https://github.com/knative/serving/blob/master/docs/runtime-contract.md#protocols-and-ports
const ( // ProtocolHTTP1 maps to HTTP/1.1. ProtocolHTTP1 ProtocolType = "http1" // ProtocolH2C maps to HTTP/2 with Prior Knowledge. ProtocolH2C ProtocolType = "h2c" )
func (ProtocolType) Validate ¶ added in v0.5.0
func (p ProtocolType) Validate(context.Context) *apis.FieldError
Validate validates that ProtocolType has a correct enum value.
type ServiceType ¶ added in v0.6.0
type ServiceType string
ServiceType is the enumeration type for the Kubernetes services that we have in our system, classified by usage purpose.
const ( // ServiceTypePrivate is the label value for internal only services // for user applications. ServiceTypePrivate ServiceType = "Private" // ServiceTypePublic is the label value for externally reachable // services for user applications. ServiceTypePublic ServiceType = "Public" // ServiceTypeMetrics is the label value for Metrics services. Such services // are used for meric scraping. // TODO(5900): Remove after 0.12 is cut. ServiceTypeMetrics ServiceType = "Metrics" )
