Functions ¶

func Proxy ¶

func Proxy(ctx context.Context, id string, conn Conn, cli client.CommonAPIClient, command Command) error

Proxy attaches to a docker container and proxies its stdin/out/err over a websocket using the terminado protocol.

func RuneCopy ¶

func RuneCopy(dst io.Writer, src io.Reader) (written int, err error)

RuneCopy is like io.Copy, but only writes valid runes, waiting for more input if invalid. This uses ScanRunesGreedy to write as much as possible per read.

func ScanRunesGreedy ¶

func ScanRunesGreedy(data []byte, atEOF bool) (advance int, token []byte, err error)

ScanRunesGreedy is like bufio.ScanRunes, but will capture as many runes from the input as possible.

func WSIsClose ¶

func WSIsClose(err error) bool

WSIsClose returns true if the error provided is a normal closure error and can be ignored. This includes io.EOF and a wsutil.ClosedError with the code set to StatusNormalClosure or StatusGoingAway.

Types ¶

type Command ¶

type Command struct {
	User       string
	Cmd        []string
	Env        []string
	WorkingDir string
}

Command is the configuration for a proxy'd command.

type Conn ¶

type Conn interface {
	ReadJSON(v interface{}) error
	WriteJSON(v interface{}) error
	Close() error
	IsClose(error) bool
}

Conn is the interface for sending proxy data to the client.

type WSConn ¶

type WSConn struct {
	// contains filtered or unexported fields
}

WSConn wraps a gobwas/ws connection.

func NewWSConn ¶

func NewWSConn(conn net.Conn) *WSConn

NewWSConn creates a new WSConn from a net.Conn.

func (*WSConn) Close ¶

func (w *WSConn) Close() error

Close closes the connection.

func (*WSConn) IsClose ¶

func (w *WSConn) IsClose(err error) bool

IsClose returns true if the error is a close. See WSIsClose.

func (*WSConn) ReadJSON ¶

func (w *WSConn) ReadJSON(v interface{}) error

ReadJSON parses the next text websocket text message into JSON.

func (*WSConn) WriteJSON ¶

func (w *WSConn) WriteJSON(v interface{}) error

WriteJSON writes a value to the websocket as JSON. It is safe for concurrent use.
