I'm running a kubernetes cluster with minikube on ubuntu server 20.04.1 LTS. When I launch the deployments I can access the Tomcat server from the cluster, but I can't open my application, I got the error message :

HTTP Status 404 – Not Found

Here is my docker-compose file :

    version: "3"

    driver: bridge

    networks:
      - network1
    volumes:

    restart: always

    networks:
      - network1
    volumes:

Here is my kubernetes deployment file :

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
spec:
  replicas: 3
  selector:
      matchLabels:
        app: myapp
  # type: LoadBalancer
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
      - name: myapp
        image: jksun12/vdsaipro
        command: ["/run.sh"]
        ports:
        - containerPort: 80
        - containerPort: 3306
        - containerPort: 9001
        - containerPort: 9002
   # volumeMounts:

   #     persistentVolumeClaim:

apiVersion: apps/v1

  labels:
    app: myapp

My application files are in the /smart directory, which is a subdirectory of the directory where I actually run docker-compose and build my main Dockerfile. How can I solve it ? Thanks
