traefik+etcd构建grpc微服务demo

1.下载安装traefik

   

https://github.com/containous/traefik/releases

2.下载安装etcd3

https://github.com/coreos/etcd/releases

3.配置traefik，监控etcd的k-v，traefik使用文档地址 https://docs.traefik.io/master/user-guide/grpc/

[etcd]
prefix = "/myservice"
watch=true
endpoint = "127.0.0.1:2379"
#APIV3=true
useAPIV3 = true
[entryPoints]
  [entryPoints.http]
    address = ":8001"  //http1,htp2的入口地址
    compress = true
  [entryPoints.bar]
    address = ":8081"
[api]
  entryPoint = "bar" //admin的入口地址
  dashboard = true
  debug = true

4.将服务信息写入ETCD 

put /myservice/backends/backend1/servers/server1/url h2c://backend.local:8080

put /myservice/frontends/frontend1/backend backend1

put /myservice/frontends/frontend1/routes/test_1/rule PathPrefix:/proto.HelloHttp/SayHello

5.启动 SayHello的GRPC服务

6.启动traefik
