Types

type Config

type Config struct {
	Context     context.Context
	Options     map[string]interface{}
	Name        string
	DisplayName string
	Description string
	UserName    string
	Executable  string
	WorkingDir  string
	RootDir     string
	Arguments   []string
}

Config provides the setup for a ServiceIface. The Name field is required.

type Iface

type Iface interface {
	Start(s ServiceIface) error
	Stop(s ServiceIface) error
}

type ServiceIface

type ServiceIface interface {
	Run() error
	Start() error
	Stop() error
	Restart() error
	Install() error
	Uninstall() error
	Status() string
	String() string
}

ServiceIface represents a service that can be run or controlled

func New

func New(i Iface, c *Config) (ServiceIface, error)

New creates a new service based on a service interface and configuration

type SystemIface

type SystemIface interface {
	String() string
	Interactive() bool
	Detect() bool
	New(i Iface, c *Config) (ServiceIface, error)
}
