PCG-第一次作业

软件92 易俊泉

基本题目

请基于//gen目录下的桩代码，基于自己熟悉的程序语言开发对应的服务端程序和客户端程序。

基本要求： 服务端程序提供PutPet、GetPet、DeletePet三个接口，客户端访问这三个服务进行宠物数据的写入、查询和删除操作。

扩展要求： 创建镜像和yaml文件基于minikube部署

完成情况

  • 基本要求
  • 扩展要求

server.go : 服务端用go实现

PetClient.java : 客户端用java实现

gotest.go : 客户端测试用go实现

操作指南

  • 客户端使用Java，镜像制作请参考：Client_Java.md

  • 服务端使用Go，镜像制作请参考：Server_Go.md

  • 有关gRPC的原理与使用，请参考：gRPC.md

快速开始

基于源码方式

环境：

  • jdk：11
  • golang：go1.19 windows/amd64
  1. 运行服务端：进入server\server.go所在目录，运行go run server.go,有如下欢迎界面即为成功
    2022/10/22 00:23:18 gRPC服务端启动成功:8088！

基于镜像方式

由于本人对k8s掌握不是很熟练，所以仅仅将两个容器放在一个pod中，便于端口访问

服务端也没有进行交互，仅仅测试一下gRPC的正常使用与部署正确

  1. 启动Docker

  2. 启动minikube

    minikube start

  3. 进入主目录，运行deploy.yaml配置文件

    kubectl apply -f deploy.yaml    

# deploy.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: grpc-deployment #要创建的 deployment 的名字
spec:
  selector: #deployment资源和pod资源关联的方式
    matchLabels:
      app: grpc
  template:
    metadata:
      labels:
        app: grpc
    spec:
      containers:
        - image: yijunquan/grpc-client:v1.0.0
          name: grpc-client-container #容器名称
          ports:
            - name: http
              protocol: TCP
              containerPort: 19090
        - image: yijunquan/grpc-server:v1.0.0
          name: grpc-server-container #容器名称
          ports:
            - name: grpc
              protocol: TCP
              containerPort: 8088

  4. 查看pods

    kubectl get pods kubectl get pods
NAME                               READY   STATUS     RESTARTS     AGE
grpc-deployment-58b6988fff-c7rwx   1/2     NotReady   1 (6s ago)   9s

  5. 根据pod名字查看运行结果

    kubectl logs grpc-deployment-58b6988fff-c7rwx
