go-plugins's Introduction

Go Plugins

A repository for go-micro and go-os plugins. The go-micro framework is a pluggable architecture, here we provide additional plugins to swap out the defaults.

Check out the Micro on NATS blog post to learn more about plugins https://blog.micro.mu/2016/04/11/micro-on-nats.html.

Usage

Plugins can be added to go-micro in the following ways. By doing so they'll be available to set via command line args or environment variables.

Import the plugin

import (
	"github.com/micro/go-micro/cmd"
	_ "github.com/micro/go-plugins/broker/rabbitmq"
	_ "github.com/micro/go-plugins/registry/kubernetes"
	_ "github.com/micro/go-plugins/transport/nats"
)

func main() {
	cmd.Init()
}

Activate via a command line flag

go run service.go --broker=rabbitmq --registry=kubernetes --transport=nats

OR use them directly

import (
	"github.com/micro/go-plugins/registry/kubernetes"
)

func main() {
	r := kubernetes.NewRegistry() // default to using env vars for master API
}
