Go-micro 简介

一句话介绍

Go Micro CLI is the command line interface for developing Go Micro projects.

开始表演

  • 安装
1

go install github.com/go-micro/cli/cmd/go-micro@latest
  • 创建测试项目（执行命令，后续根据命令提示操作）
1

go-micro new service helloworld
  • 创建工程化项目（执行命令，后续根据命令提示操作）
1

go-micro new service --jaeger --health --grpc --advanced

注： 1、 Since Kubernetes 1.24, probes can make use of the gRPC Health Protocol. This allows you to directly probe the go-micro service in a Kubernetes container if it implements the health protocol. 2、By default, go-micro uses an JSON/HTTP RPC server. Many microservice use cases require a gRPC server or client, therefore, go-micro offers a gRPC server built in. gRPC默认使用HTTP/2作为其传输协议，并使用Protocol Buffers（protobuf）作为默认的消息序列化和接口定义语言

  • 添加工程化插件 1、consul 配置和服务发现中心

  • 本地测试接口
