无法在Kubernetes上访问公开的Dockerized React应用程序

我正在尝试将我的Dockerized React应用程序部署到Kubernetes . 我相信我已正确定位它，但我无法访问暴露的pod .

我没有Docker或Kubernetes的经验，所以任何帮助都将不胜感激 .

我的React应用程序只是从Tomcat提供的静态文件（来自npm run build） .

我的Dockerfile在下面 . 总之，我将我的应用程序放在Tomcat文件夹中并公开端口8080 .

FROM private-docker-registry.com/repo/tomcat:latest

EXPOSE 8080:8080

# Copy build directory to Tomcat webapps directory
RUN mkdir -p /tomcat/webapps/app
COPY /build/sample-app /tomcat/webapps/app

# Create a symbolic link to ROOT -- this way app starts at root path 
(localhost:8080)

RUN ln -s /tomcat/webapps/app /tomcat/webapps/ROOT

# Start Tomcat
ENTRYPOINT ["catalina.sh", "run"]

我构建并将Docker镜像推送到私有Docker Registry . 我通过运行它来验证容器是否正确运行：

docker run -p 8080:8080 private-docker-registry.com/repo/sample-app:latest

然后，如果我去localhost：8080，我会看到我的React应用程序的主页 .

现在，我遇到的麻烦是部署到Kubernetes并从外部访问应用程序 .

这是我的deployment.yaml文件：

kind: Deployment
apiVersion: apps/v1beta2
metadata:
  name: sample-app
  namespace: dev
  labels:
    app: sample-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: sample-app
  template:

      labels:
        app: sample-app
    spec:
      containers:
      - name: sample-app
        image: private-docker-registry.com/repo/sample-app:latest
        ports:
        - containerPort: 8080
          protocol: TCP
      nodeSelector:
        TNTRole: luxkube

kind: Service

spec:
  selector:
    app: sample-app
  type: NodePort
  ports:
  - port: 80
    targetPort: 8080
    protocol: TCP

我通过运行kubectl --namespace = dev create -f deployment.yaml创建了部署和服务

现在我不知道我应该使用哪个IP和端口来访问应用程序 . 我尝试了所有组合但没有加载我的应用程序 . 我相信端口应该是80，所以如果我只有IP，我可以通过访问http：//来访问浏览器并访问React应用程序 .

有没有人有建议？
