Functions ¶

func ServePortForward ¶

func ServePortForward(w http.ResponseWriter, req *http.Request, portForwarder PortForwarder, podName string, uid types.UID, idleTimeout time.Duration, streamCreationTimeout time.Duration)

ServePortForward handles a port forwarding request. A single request is kept alive as long as the client is still alive and the connection has not been timed out due to idleness. This function handles multiple forwarded connections; i.e., multiple `curl http://localhost:8888/` requests will be handled by a single invocation of ServePortForward.

Types ¶

type PortForwarder ¶

type PortForwarder interface {
	// PortForwarder copies data between a data stream and a port in a pod.
	PortForward(name string, uid types.UID, port uint16, stream io.ReadWriteCloser) error
}

PortForwarder knows how to forward content from a data stream to/from a port in a pod.
