示例1: ConfigureTaskDir

// ConfigureTaskDir creates the necessary directory structure for a proper
// chroot. cleanTaskDir should be called after.
func (e *LinuxExecutor) ConfigureTaskDir(taskName string, alloc *allocdir.AllocDir) error {
	e.taskName = taskName
	e.allocDir = alloc.AllocDir

	taskDir, ok := alloc.TaskDirs[taskName]
	if !ok {
		fmt.Errorf("Couldn't find task directory for task %v", taskName)
	}
	e.taskDir = taskDir

	if err := alloc.MountSharedDir(taskName); err != nil {
		return err
	}

	// Embed ourselves if this is a test. This needs to be done so the test
	// binary is inside the chroot.
	if isTest(&e.cmd) {
		bin := e.cmd.Args[0]
		alloc.Embed(taskName, map[string]string{bin: bin})
	}

	if err := alloc.Embed(taskName, chrootEnv); err != nil {
		return err
	}

	// Mount dev
	dev := filepath.Join(taskDir, "dev")
	if !e.pathExists(dev) {
		if err := os.Mkdir(dev, 0777); err != nil {
			return fmt.Errorf("Mkdir(%v) failed: %v", dev, err)
		}

		if err := syscall.Mount("", dev, "devtmpfs", syscall.MS_RDONLY, ""); err != nil {
			return fmt.Errorf("Couldn't mount /dev to %v: %v", dev, err)
		}
	}

	// Mount proc
	proc := filepath.Join(taskDir, "proc")
	if !e.pathExists(proc) {
		if err := os.Mkdir(proc, 0777); err != nil {
			return fmt.Errorf("Mkdir(%v) failed: %v", proc, err)
		}

		if err := syscall.Mount("", proc, "proc", syscall.MS_RDONLY, ""); err != nil {
			return fmt.Errorf("Couldn't mount /proc to %v: %v", proc, err)
		}
	}

	// Set the tasks AllocDir environment variable.
	env, err := environment.ParseFromList(e.cmd.Env)
	if err != nil {
		return err
	}
	env.SetAllocDir(filepath.Join("/", allocdir.SharedAllocName))
	env.SetTaskLocalDir(filepath.Join("/", allocdir.TaskLocal))
	e.cmd.Env = env.List()

	return nil
