Golang DirFlag Examples

Example #1

File: naive_baggageclaim.go Project: sclevine/bin

func (cmd *WorkerCommand) naiveBaggageclaimRunner(logger lager.Logger) (ifrit.Runner, error) {
	volumesDir := filepath.Join(cmd.WorkDir, "volumes")

	err := os.MkdirAll(volumesDir, 0755)
	if err != nil {
		return nil, err
	}

	bc := &baggageclaimcmd.BaggageclaimCommand{
		BindIP:   baggageclaimcmd.IPFlag(cmd.Baggageclaim.BindIP),
		BindPort: cmd.Baggageclaim.BindPort,

		VolumesDir: baggageclaimcmd.DirFlag(volumesDir),

		Driver: "naive",

		ReapInterval: cmd.Baggageclaim.ReapInterval,

		Metrics: cmd.Metrics,
	}

	return bc.Runner(nil)
}

	volumesImage := filepath.Join(cmd.WorkDir, "volumes.img")

	err := os.MkdirAll(volumesDir, 0755)
	if err != nil {
		return nil, err
	}

	var fsStat syscall.Statfs_t
	err = syscall.Statfs(volumesDir, &fsStat)
	if err != nil {
		return nil, fmt.Errorf("failed to stat volumes filesystem: %s", err)
	}

	filesystem := fs.New(logger.Session("fs"), volumesImage, volumesDir)

	err = filesystem.Create(fsStat.Blocks * uint64(fsStat.Bsize))
