How to run a Exec

[NhanHoThanh]

How to run the Exec instance after create it, I have dig throught the repo but cant find a way to make it work, here is my code below:

    public String testDockerClient () {
        try{
            final Docker dockerClient = new UnixDocker(new File("/var/run/docker.sock"));
            final Container started = dockerClient.containers().create("my-python-runner:latest");



            JsonArray cmdArray = Json.createArrayBuilder()
                .add("echo")
                .add("helloword")
                .build();

            JsonObject execConfig = Json.createObjectBuilder()
                .add("Cmd", cmdArray)
                .add("AttachStdin", false)
                .add("AttachStdout", true)
                .add("AttachStderr", true)
                .add("Tty", false)
                .build();

            started.start();

            Exec output = started.exec(execConfig);
            System.out.println("output: " + output.inspect());
            Logs log = started.logs();
            System.out.println("log: " + log.toString());
            started.stop();
            started.remove();

            return "Success";


        } catch (Exception e) {
            return "Error: " + e.getMessage();
        }

If you look at the RtContainer.exec(...) method, you can see the Exec is created with a POST request to Docker's API. Then, you get an instance of RtExec representing the created Exec.

If the created Exec is not run automatically, then I assume there should be a method for it, something like Exec/RtExec.run() or start() - however, this is missing at the moment.

Please note that this library is incomplete; PRs are welcome if you have the time for it. :)
