Types

type Watcher

type Watcher struct {

	// FilePath is the path to the file to watch.
	FilePath string

	// Log is the logger to be used in the File backend.
	Log logr.Logger
	// contains filtered or unexported fields
}

Watcher represents the backend for watching a file for changes and updating the in memory DHCP data.

func NewWatcher

func NewWatcher(l logr.Logger, f string) (*Watcher, error)

NewWatcher creates a new file watcher.

func (*Watcher) GetByIP

func (w *Watcher) GetByIP(ctx context.Context, ip net.IP) (*data.DHCP, *data.Netboot, error)

GetByIP is the implementation of the Backend interface. It reads a given file from the in memory data (w.data).

func (*Watcher) GetByMac

func (w *Watcher) GetByMac(ctx context.Context, mac net.HardwareAddr) (*data.DHCP, *data.Netboot, error)

GetByMac is the implementation of the Backend interface. It reads a given file from the in memory data (w.data).

func (*Watcher) Start

func (w *Watcher) Start(ctx context.Context)

Start starts watching a file for changes and updates the in memory data (w.data) on changes. Start is a blocking method. Use a context cancellation to exit.
