Types

type Daemon

type Daemon struct {
	// contains filtered or unexported fields
}

Daemon is a daemon for windows agents with grpc support.

func New

func New(ctx context.Context, registerGRPCServices GRPCServiceRegisterer, addrDir string) *Daemon

New returns an new, initialized daemon server that is ready to register GRPC services. It hooks up to windows service management handler.

func (Daemon) Quit

func (d Daemon) Quit(ctx context.Context, force bool)

Quit gracefully quits listening loop and stops the grpc server. It can drop any existing connexion if force is true.

func (Daemon) Serve

func (d Daemon) Serve(ctx context.Context, args ...Option) (err error)

Serve listens on a tcp socket and starts serving GRPC requests on it. Before serving, it writes a file on disk on which port it's listening on for client to be able to reach our server. This file is removed once the server stops listening.

type GRPCServiceRegisterer

type GRPCServiceRegisterer func(ctx context.Context) *grpc.Server

GRPCServiceRegisterer is a function that the daemon will call everytime we want to build a new GRPC object.

type Option

type Option func(*options)

Option represents an optional function to override getWslIP default values.
