启动多个服务

如何在 rk-boot 中，启动多个服务？

概述

通过 rk-boot，用户可以在一个进程里面，启动多个 Entry。

用户还可以同时启动 Fiber 服务和 gRPC 等服务。

快速开始

1.安装

$ go get github.com/rookie-ninja/rk-boot/v2
$ go get github.com/rookie-ninja/rk-fiber

2.创建 boot.yaml

fiber:
  - name: alice
    port: 8080
    enabled: true
  - name: bob
    port: 8081
    enabled: true

3.创建 main.go

package main

import (
  "context"
  "fmt"
  "github.com/gofiber/fiber/v2"
  "github.com/rookie-ninja/rk-boot/v2"
  "github.com/rookie-ninja/rk-fiber/boot"
  "net/http"
)

func main() {
  // Create a new boot instance.
  boot := rkboot.NewBoot()

  // Bootstrap
  boot.Bootstrap(context.TODO())

  // Register handler
  alice := rkfiber.GetFiberEntry("alice")
  alice.App.Get("/v1/greeter", Greeter)
  alice.RefreshFiberRoutes()

  bob := rkfiber.GetFiberEntry("bob")
  bob.App.Get("/v1/greeter", Greeter)
  bob.RefreshFiberRoutes()

  boot.WaitForShutdownSig(context.TODO())
}

// Greeter handler
// @Summary Greeter
// @Id 1
// @Tags Hello
// @version 1.0
// @Param name query string true "name"
// @produce application/json
// @Success 200 {object} GreeterResponse
// @Router /v1/greeter [get]
func Greeter(ctx *fiber.Ctx) error {
  ctx.Response().SetStatusCode(http.StatusOK)
  return ctx.JSON(&GreeterResponse{
    Message: fmt.Sprintf("Hello %s!", ctx.Query("name")),
  })
}

type GreeterResponse struct {
  Message string
}

4.验证

$ curl  "localhost:8080/v1/greeter?name=rk-dev"
{"Message":"Hello rk-dev!"}

$ curl  "localhost:8081/v1/greeter?name=rk-dev"
{"Message":"Hello rk-dev!"}
