为什么我无法通过tomcat服务器访问Kubernetes集群中的应用程序？

如何解决为什么我无法通过tomcat服务器访问Kubernetes集群中的应用程序？

我在ubuntu服务器20.04.1 LTS上运行带有minikube的kubernetes集群。启动部署时，我可以从群集访问Tomcat服务器，但是无法打开我的应用程序，我收到了错误消息：

HTTP Status 404 – Not Found

这是我的docker-compose文件：

    version: "3"

  network1:
    driver: bridge
volumes:

    driver_opts:
      device: /smartclass_docker/site/

      - "8080:8080"

    ## Startup policy
    restart: always

    # connect to network1
    networks:
      - network1
    volumes:
            - /data/dockerStore/data/db_server_1:/var/lib/mysql/

    restart: always

    # connect to network1
    networks:
      - network1
    volumes:
            - /data/dockerStore/data/db_server_1:/var/lib/mysql/

这是我的kubernetes部署文件：

我的应用程序文件位于/ smart目录中，该目录是我实际运行docker-compose并构建主Dockerfile的目录的子目录。 我该如何解决？ 谢谢

解决方法

我检查了容器内的日志，发现错误来自容器内.war文件的提取。 用于该应用程序的tomcat服务器的版本中也存在一个错误。所以我将tomcat的版本更改为另一个版本。

现在解决了。谢谢
