Etcd 场景练习 (Go)
======================

DESCRIPTION
-------------
go-etcd场景练习  (Etcd V3 服务注册与发现)


PREREQUISITES
-------------

- This requires Go 1.14 or later
- Requires that [GOPATH is set](https://golang.org/doc/code.html#GOPATH)

```
$ go help gopath
$ # ensure the PATH contains $GOPATH/bin
$ export PATH=$PATH:$GOPATH/bin
```

INSTALL
-------

```
git clone https://github.com/Dingjianhui/go-etcd.git
cd go-etcd
go mod tidy

```

CONFIG
-------

server/main.go
```go
	// 1. 创建服务-获取商品详情
	serviceId := uuid.New().String()        // 服务ID
	serviceName := "productDetailService"   // 服务名
	serviceAddress := "192.168.123.178"     // 服务地址
	servicePort := 8081                     // 服务端口
```

server/utils/Service.go 中配置Etcd  的节点更改为自己的Etcd节点信息

client/utils/Client.go 中配置Etcd  的节点更改为自己的Etcd节点信息

```go
	// 配置 etcd
	config := clientv3.Config{
		Endpoints:     []string{"192.168.137.132:23791","192.168.137.132:23792","192.168.137.132:23793"},
		DialTimeout:   10*time.Second,
	}
```

[使用docker模拟etcd集群的创建](http://dingjianhui.top/blog/2020/06/11/etcd-cluster-by-docker/)

TRY IT!
-------

- Run the server(服务注册)

  ```
  $ go run server/main.go
  ```
  

- Run the client(服务发现)

  ```
  $ go run client/main.go
  ```
