SpringBoot应用代码 #

/**
 * @author zhengtao on 2023/12/2
 */
@RestController
public class TestController {

    @RequestMapping("/hello")
    public String helloWorld() {
        return "hello world";
    }
}

部署配置文件 #

Deployment配置（docker-study-deployment.yaml） #

apiVersion: apps/v1
kind: Deployment
metadata:
  name: docker-study-deployment
spec:
  selector:
    matchLabels:
      app: docker-study-deployment
  replicas: 2
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
  template:
    metadata:
      labels:
        app: docker-study-deployment
    spec:
      containers:
      - name: docker-study
        image: wzgl998877/docker-study
        ports:
        - containerPort: 80

Service配置（docker-study-svc.yaml） #

apiVersion: v1
kind: Service
metadata:
  name: docker-study-svc

spec:
  selector:
    app: docker-study-deployment

  ports:
  - port: 80
    targetPort: 8080
    protocol: TCP
  type: NodePort

问题现象 #

已执行kubectl apply -f docker-study-deployment.yaml完成部署，执行kubectl apply -f docker-study-svc.yaml创建Service，确认deployment和service均处于运行状态。但：

• 执行curl http://10.97.154.229:30577/hello无响应
• 进入Pod内执行curl http://10.97.154.229:8080/hello，返回curl: (7) Failed to connect to 10.97.154.229 port 8080: Connection refused

恳请协助解决该问题，谢谢！
