Simple Daemon

A super-simple wrapper for making a simple cross-platform service. With only a few lines of code, you can install and run your process as a daemon/service.

Getting Started

Get this repository:

go get github.com/markdicksonjr/simple-daemon

Initialize a simple daemon instance with the basic information about the service (like name and description), along with the behavior of the service (most importantly, the function that does the work).

import (
	simple_daemon "github.com/markdicksonjr/simple-daemon"
	"log"
)

func main() {
	if err := simple_daemon.Start(simple_daemon.Info{
		Name:         "Test",
		Description:  "A simple test daemon",
		Dependencies: nil,
	}, simple_daemon.Behavior{
		WorkFn: func() error {
			log.Println("simple log")
			return nil
		},
        UseExeDirAsCwd: true,
	}); err != nil {
		log.Fatal(err)
	}
}

This will create the service with the name and description provided. On Windows, the service will be "auto" and will run immediately. The "UseExeDirAsCwd" flag determines whether or not the working directory is set to wherever the exe is run from. Typically, if this is false on windows, this means the current directory will be something like C:/Windows/system32 or such.

Service Lifecycle

The various lifecycle stages of services can be managed (by default):

binaryName install or binaryName install [args...]

binaryName uninstall

binaryName start

binaryName stop

binaryName status

For direct invocation:

binaryName ...otherArgs
