Golang New Examples

Example #1

File: server.go Project: nkts/golang-devops-stuff

func (s *WardenServer) Start() error {
	err := s.removeExistingSocket()
	if err != nil {
		return err
	}

	err = s.backend.Start()
	if err != nil {
		return err
	}

	listener, err := net.Listen(s.listenNetwork, s.listenAddr)
	if err != nil {
		return err
	}

	s.listener = listener

	if s.listenNetwork == "unix" {
		os.Chmod(s.listenAddr, 0777)
	}

	containers, err := s.backend.Containers()
	if err != nil {
		return err
	}

	s.bomberman = bomberman.New(s.reapContainer)

	for _, container := range containers {
		s.bomberman.Strap(container)
	}

	go s.trackStopping()
	go s.handleConnections(listener)

	return nil
