示例1: updateTUFClient

// updateTUFClient updates the given client, initializing and re-running the
// update if ErrNoRootKeys is returned.
func updateTUFClient(client *tuf.Client) error {
	_, err := client.Update()
	if err == nil || tuf.IsLatestSnapshot(err) {
		return nil
	}
	if err == tuf.ErrNoRootKeys {
		if err := client.Init(rootKeys, len(rootKeys)); err != nil {
			return err
		}
		return updateTUFClient(client)
	}
	return err

示例3: updateAndExecLatest

// updateAndExecLatest updates the tuf DB, downloads the latest flynn-host
// binary to a temp file and execs it.
//
// Latest snapshot errors are ignored because, even though we may have the
// latest snapshot, the cluster may not be fully up to date (a previous update
// may have failed).
func updateAndExecLatest(configDir string, client *tuf.Client, log log15.Logger) error {
	log.Info("updating TUF data")
	if _, err := client.Update(); err != nil && !tuf.IsLatestSnapshot(err) {
		log.Error("error updating TUF client", "err", err)
		return err
	}

	version, err := getChannelVersion(configDir, client, log)
	if err != nil {
		return err
	}

	log.Info(fmt.Sprintf("downloading %s flynn-host binary", version))
	gzTmp, err := tufutil.Download(client, path.Join(version, "flynn-host.gz"))
	if err != nil {
		log.Error("error downloading latest flynn-host binary", "err", err)
		return err
	}
	defer gzTmp.Close()

		return err
	}
	_, err = io.Copy(tmp, gz)
	tmp.Close()
	if err != nil {
		log.Error("error decompressing gzipped flynn-host binary", "err", err)
		return err
	}
	if err := os.Chmod(tmp.Name(), 0755); err != nil {

示例4: GetVersion

// GetVersion returns the given target's version from custom metadata

	if err != nil {
		return "", err
	}
	target, ok := targets[name]
	if !ok {
		return "", fmt.Errorf("missing %q in tuf targets", name)
	}
	if target.Custom == nil || len(*target.Custom) == 0 {
		return "", errors.New("missing custom metadata in tuf target")
	}
	var data struct {
		Version string
	}
	json.Unmarshal(*target.Custom, &data)
	if data.Version == "" {
		return "", errors.New("missing version in tuf target")
	}
	return data.Version, nil
}
