Pseudo-constants

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

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"
)
