I need to access to two differents Worker nodes for the same nodePort 30150.

Service1.yml

apiVersion: v1
kind: Service
metadata:
  namespace: postgres
  name: postgres-db-node1-service
  labels:
    name: database
    node: node1
    system: postgres
spec:
  type: NodePort
  ports:
    - port: 5432
      targetPort: 5432
      nodePort: 30150
  selector:
    name: database
    **node: node1**
    system: postgres

Service2.yml

apiVersion: v1
kind: Service
metadata:
  namespace: postgres
  name: postgres-db-node2-service
  labels:
    name: database
    node: node2
    system: postgres
spec:
  type: NodePort
  ports:
    - port: 5432
      targetPort: 5432
      nodePort: 30150
  selector:
    name: database
    **node: node2**
    system: postgres

However, It failed when the service2 is applied:

The Service "postgres-db-node1-service" is invalid: spec.ports[0].nodePort: Invalid value: 30150: provided port is already allocated

Why couldn't I use the same port for different nodes? Or how could I solve that with Kubernetes?

Thank you in advance for your help!
