Exec with Stdin

[jsrun]

Hi all, I would like to know how it would be possible to use the exec command and in case of commands that require data input I can send, for example:

In case I get the commands via socket.io and send to the container via exec, and it works perfectly more in the case of apt-get install for example that needs digital Y / N when I send the command it's like another "thread"

socket.on('stdin', function (data) {
    container.exec({Cmd: data.split(" "), AttachStdin: true, AttachStdout: true}, function(err, exec) {
        exec.start({hijack: true, stdin: true}, function(err, stream) {
            stream.on('data', function(chunk) {
                io.sockets.emit("stdout", chunk.toString());
                console.log(chunk.toString());
            });

            stream.on('error', function(err) {
                io.sockets.emit("stderr", err.toString());
                console.log(err.toString());
            });

            stream.on('end', function(chunk) {
                io.sockets.emit("enable");
            });

            docker.modem.demuxStream(stream, process.stdout, process.stderr);
        });
    });
});
