Types ¶
type ConnObserver ¶
type ConnObserver interface {
// OnMarkDead is called when the client for the id is disconnected.
OnMarkDead(id string)
}
ConnObserver is the interface to receive updates on the connections.
type HTTPProxy ¶
type HTTPProxy struct {
// contains filtered or unexported fields
}
HTTPProxy is a http/2 client that can proxy requests along one of multiple connections corresponding to identifying information on the incoming request.
func (*HTTPProxy) Proxy ¶
func (t *HTTPProxy) Proxy(w http.ResponseWriter, r *http.Request)
Proxy proxies a HTTP request to an agent using the appropriate connection.
func (*HTTPProxy) SetObserver ¶
func (t *HTTPProxy) SetObserver(obs ConnObserver)
SetObserver sets the ConnObserver to its connection pool.
type Proxy ¶
type Proxy interface {
// Add adds the net.Conn with the given identifier to the Proxy
Add(id string, c net.Conn) error
// Proxy routes the HTTP on the appropriate connection.
Proxy(w http.ResponseWriter, r *http.Request)
// Status returns the current status of the Proxy.
Status() Status
}
Proxy routes HTTP requests along one of many connections, corresponding to identifying information on the request.
type Status ¶
type Status struct {
Type string `json:"type"`
Tunnels []TunnelStatus `json:"tunnels"`
}
Status is the current state of the proxy.
type TunnelStatus ¶
TunnelStatus is the current state of a tunnel to an agent.
type UpgradeProxy ¶
type UpgradeProxy struct {
// contains filtered or unexported fields
}
UpgradeProxy proxies requests on connections that need to be "upgraded" before non-HTTP traffic can be sent on the connection (e.g. SPDY for kubectl exec, etc.), possibly in either direction.
func NewUpgradeProxy ¶
func NewUpgradeProxy() *UpgradeProxy
NewUpgradeProxy returns a new ConnectProxy.
func (*UpgradeProxy) Add ¶
func (t *UpgradeProxy) Add(id string, c net.Conn) error
Add adds the connection to the connection pool.
func (*UpgradeProxy) OnMarkDead ¶
func (t *UpgradeProxy) OnMarkDead(id string)
OnMarkDead implements ConnObserver.OnMarkDead.
This function closes all connections for the given ID. The intention is to call this function to close HTTP/1 connections when a corresponding HTTP/2 connection is closed.
func (*UpgradeProxy) Proxy ¶
func (t *UpgradeProxy) Proxy(w http.ResponseWriter, r *http.Request)
Proxy proxies a HTTP requests that need to be "upgraded" (i.e. for kubectl exec, port-forward, etc.).
Following the upgrade between the proxy and the agent, the connection between the client and the proxy is "hijacked". The two sides of the connection (client -> proxy, and proxy -> agent) can then be bridged to allow bidirectional traffic flow.
func (*UpgradeProxy) Status ¶
func (t *UpgradeProxy) Status() Status
Status returns the current status of the proxy.
