安装包

go get github.com/outreach-golang/etcd

在go.mod 里添加引用

因为etcd和grpc本身的兼容性问题，所以需要添加某些包的替换

replace (
    github.com/coreos/bbolt => go.etcd.io/bbolt v1.3.5
    github.com/coreos/go-systemd => github.com/coreos/go-systemd/v22 v22.0.0
    google.golang.org/grpc => google.golang.org/grpc v1.26.0
)

初始化etcd客户端

import "github.com/outreach-golang/etcd"

if err = etcd.GEtcd.InitEtcd(
   //环境变量值（DefaultEV,TestingEV,ReleaseEV,ProductionEV）
   etcd.EnvVar(etcd.DefaultEV),
   //etcd地址
   etcd.Points([]string{"127.0.0.1:2379"}),
); err != nil {
    log.Fatal(err.Error())
}

支持SSL配置，可自行加相应配置项即可

将服务注册到etcd

etcdRegister := etcd.NewServiceRegister(etcd.GEtcd.GetCli())

if err = etcd.ServiceRegisterHandler.InitServiceRegister(
    context.Background(),
    etcdRegister,
    "server.AppName",
    "server.port"); err != nil {
    log.Fatal(err.Error())
}
