I'm trying to create two containers (tomact image) inside my web pod:
each one going to run a java application but I want them to share the same 
ip address 

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: web-dp
  labels:
    name: web-pod
    version: v1
spec:
  template:
    metadata:
      labels:
        name: web-pod
        version: v1
    spec:
      containers:
      - image: gcr.io/projectid/webapp:1
        name: web-pod
        ports:
        - containerPort: 8080
      - image: gcr.io/projectid/webapp:2
        name: crm-pod
        ports:
        - containerPort: 8081
-------------
apiVersion: v1
kind: Service
metadata:
  name: web-service
  labels:
    name: web-pod
    version: v1
spec:
  type: NodePort
  ports:
    - port: 80
      targetPort: 8080
      protocol: TCP
      name: app1
      nodePort: 30531
    - port: 80
      targetPort: 8081
      protocol: TCP
      name: app2
      nodePort: 31352
  selector:
    name: web-pod

I'm using an NGINX-ingress-controller+Ingress for the service

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: amenity-smartlab-ing
  annotations:
    kubernetes.io/ingress.class: "nginx"
spec:
  rules:
  - http:
      paths:
      - backend:

          serviceName: web-service
          servicePort: 80
        path: /

I get this error in my logs
java.lang.Exception: Socket bind failed: [98] *Address* already in use 
<https://www.google.ca/search?q=java.lang.Exception%3A+Socket+bind+failed%3A+%5B98%5D+Address+already+in+use&oq=java.lang.Exception%3A+Socket+bind+failed%3A+%5B98%5D+Address+already+in+use&aqs=chrome..69i57j69i60&sourceid=chrome&ie=UTF-8#q=kubernetes+Socket+bind+failed:+%5B98%5D+Address+already+in+use&*>
