Add Service

You can add your service in service folder

                |-echo.toml

    |-README.md

Here is a example that you have to do.

1. Import "rpc_server/core/rpc"
2. Use rpc.Register() when init()
3. Implement your service

package service

// 1. Import "rpc_server/core/rpc"
import (
	"rpc_server/core/rpc"
)

// 2. Use rpc.Register() when init()
func init() {
	rpc.Register("Echo", "A Echo Service", &Echo{})
}

// 3. Implement your service
// Echo echo service
type Echo struct{}

//Ping Ping
func (d *Echo) Ping(args *string, result *string) (rpcErr error) {
	*result = "Pong"
	return
}

Docker Compose Example

Simulation multi services in local envrionment. Use docker-compose.

docker-compose up

Add your services to docker-compose.yaml

version: '2'

services:
    echo:
        build: .
        hostname: echo
        environment:
            - ENV=local
            - SERVICE=Echo
            - TZ=Asia/Taipei

    math:
        build: .
        hostname: math
        environment:
            - ENV=local
            - SERVICE=Math
            - TZ=Asia/Taipei

Run All Service At Once

We used to run one service at one pod or one mechine in production envrionment. But if you want to start all at once, here is it.

SERVICE=All ENV=local go run main.go
