示例1: parseUserGroup

// parseUserGroup parses the User and Group fields of an App and returns its
// UID and GID.
// The User and Group fields accept several formats:
//   1. the hardcoded string "root"
//   2. a path
//   3. a number
//   4. a name in reference to /etc/{group,passwd} in the image
// See https://github.com/appc/spec/blob/master/spec/aci.md#image-manifest-schema
func parseUserGroup(p *stage1commontypes.Pod, ra *schema.RuntimeApp) (int, int, error) {
	var uidResolver, gidResolver user.Resolver
	var uid, gid int
	var err error

	root := common.AppRootfsPath(p.Root, ra.Name)

	uidResolver, err = user.NumericIDs(ra.App.User)
	if err != nil {
		uidResolver, err = user.IDsFromStat(root, ra.App.User, &p.UidRange)
	}

	if err != nil {
		uidResolver, err = user.IDsFromEtc(root, ra.App.User, "")
	}

	if err != nil { // give up
		return -1, -1, errwrap.Wrap(fmt.Errorf("invalid user %q", ra.App.User), err)
