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 Gin 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-gin/v2
2.创建 boot.yaml#
gin:
- name: alice
port: 8080
enabled: true
- name: bob
port: 8081
enabled: true
3.创建 main.go#
package main
import (
"context"
"fmt"
"github.com/gin-gonic/gin"
"github.com/rookie-ninja/rk-boot/v2"
"github.com/rookie-ninja/rk-gin/v2/boot"
"net/http"
)
func main() {
// Create a new boot instance.
boot := rkboot.NewBoot()
// Register handler
alice := rkgin.GetGinEntry("alice")
alice.Router.GET("/v1/greeter", Greeter)
bob := rkgin.GetGinEntry("bob")
bob.Router.GET("/v1/greeter", Greeter)
// Bootstrap
boot.Bootstrap(context.TODO())
boot.WaitForShutdownSig(context.TODO())
}
func Greeter(ctx *gin.Context) {
ctx.JSON(http.StatusOK, &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!"}
