const PortForwardProtocolV1Name = "portforward.k8s.io"

TODO move to API machinery and re-unify with kubelet/server/portfoward The subprotocol "portforward.k8s.io" is used for port forwarding.

Types

type ForwardedPort

type ForwardedPort struct {
	Local  uint16
	Remote uint16
}

ForwardedPort contains a Local:Remote port pairing.

type PortForwarder

type PortForwarder struct {
	Ready chan struct{}
	// contains filtered or unexported fields
}

PortForwarder knows how to listen for local connections and forward them to a remote pod via an upgraded HTTP request.

func New

func New(dialer httpstream.Dialer, ports []string, stopChan <-chan struct{}, readyChan chan struct{}, out, errOut io.Writer) (*PortForwarder, error)

New creates a new PortForwarder.

func (*PortForwarder) Close

func (pf *PortForwarder) Close()

func (*PortForwarder) ForwardPorts

func (pf *PortForwarder) ForwardPorts() error

ForwardPorts formats and executes a port forwarding request. The connection will remain open until stopChan is closed.
