示例1: register

// register makes a container object usable by the daemon as <container.ID>
func (daemon *Daemon) register(container *Container, updateSuffixarray bool) error {
	if container.daemon != nil || daemon.Exists(container.ID) {
		return fmt.Errorf("Container is already loaded")
	}
	if err := validateID(container.ID); err != nil {
		return err
	}
	if err := daemon.ensureName(container); err != nil {
		return err
	}

	container.daemon = daemon

	// Attach to stdout and stderr
	container.stderr = broadcastwriter.New()
	container.stdout = broadcastwriter.New()
	// Attach to stdin
	if container.Config.OpenStdin {
		container.stdin, container.stdinPipe = io.Pipe()
	} else {
		container.stdinPipe = ioutils.NopWriteCloser(ioutil.Discard) // Silently drop stdin
	}
	// done
	daemon.containers.Add(container.ID, container)

	// don't update the Suffixarray if we're starting up
	// we'll waste time if we update it for every container
	daemon.idIndex.Add(container.ID)

	// FIXME: if the container is supposed to be running but is not, auto restart it?
	//        if so, then we need to restart monitor and init a new lock
	// If the container is supposed to be running, make sure of it
	if container.IsRunning() {
		log.Debugf("killing old running container %s", container.ID)

		existingPid := container.Pid
		container.SetStopped(&execdriver.ExitStatus{ExitCode: 0})

		// We only have to handle this for lxc because the other drivers will ensure that
		// no processes are left when docker dies
		if container.ExecDriver == "" || strings.Contains(container.ExecDriver, "lxc") {
			lxc.KillLxc(container.ID, 9)
		} else {
			// use the current driver and ensure that the container is dead x.x
			cmd := &execdriver.Command{
				ID: container.ID,
			}
			var err error
			cmd.ProcessConfig.Process, err = os.FindProcess(existingPid)
