# nacos
EN [中文](./README_zh.md)
This project is a demo project for demonstrating how to use Nacos for service discovery
in go-doudou RESTful service application. It also shows how to call each other between
go-doudou service and spring cloud service.
## Prerequisite
- Docker for Desktop
- Modern Browser
- CLI tool
- IDE, recommend goland
- Http request tool, recommend [httpie](https://github.com/httpie/httpie)
## Steps
1. Start Nacos server in standalone mode
```shell
docker-compose -f docker-compose.yml up -d
```
```shell
➜ nacos git:(master) ✗ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
2e5400f6d085 nacos/nacos-server:v2.0.4 "bin/docker-startup.…" 18 minutes ago Up 18 minutes (healthy) 0.0.0.0:8848->8848/tcp, :::8848->8848/tcp, 0.0.0.0:9848->9848/tcp, :::9848->9848/tcp nacos-standalone
```
2. Change to `statsvc` directory, run below command to start go-doudou service
```shell
go mod tidy && go run cmd/main.go
```
If you see below output log, the service has started successfully
```shell

```
Now, you can open browser and navigate to http://localhost:8848/nacos, login and click `/ServiceManagement/Service List`
in sidebar menu, then you can see `statsvc` service has been registered to Nacos server.
3. Change to `nacos-service-j` directory, run below command to start spring cloud service
```shell
mvn spring-boot:run
```
If you see below output log, the service has started successfully
```shell
2022-03-12 13:32:41.630 INFO 88684 --- [t.remote.worker] com.alibaba.nacos.common.remote.client : [f1bf3cba-e469-43c7-a8b8-83457ee4c153] Notify connected event to listeners.
2022-03-12 13:32:41.706 INFO 88684 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s): 8080 (http) with context path '/nacos-service-j'
2022-03-12 13:32:41.723 INFO 88684 --- [ main] c.a.c.n.registry.NacosServiceRegistry : nacos registry, DEFAULT_GROUP nacos-service-j 192.168.43.200:8080 register finished

```
Now, if you refresh `/ServiceManagement/Service List` page, you can see `nacos-service-j` service has been registered to Nacos server.
4. Test `statsvc` service
```shell
➜ nacos git:(master) ✗ http http://localhost:6060/api/echo\?s\=go-doudou
HTTP/1.1 200 OK
Content-Encoding: gzip
Content-Length: 67
Content-Type: application/json; charset=UTF-8
Date: Sat, 12 Mar 2022 05:37:43 GMT
Vary: Accept-Encoding
{
"data": "Hello Nacos Discovery go-doudou"
}
```
5. Test `nacos-service-j` service
```shell
➜ nacos git:(master) ✗ http http://localhost:8080/nacos-service-j/add\?x\=50\&y\=20
HTTP/1.1 200
Connection: keep-alive
Content-Type: application/json
