I have a kubernetes cluster set up in a private cloud. Idea is all the developers would be using this cluster to launch all the microservices needed for the app. Each developer would launch all the deployments/services in his namespace to avoid collision. Since this cloud doesn't support LoadBalancer , I have used nodePort with a port defined to expose external IP for the front end. And I access the front end using

http://node-ip:port

However Since K8s can launch any number of front-end pods of different namespaces on the same node -I will have a collision because that nodePort is already assigned to the service launched first. I now cant understand on how can I allow multiple people using same services to launch in the same cluster.

Sample Service Config is below

apiVersion: v1
kind: Service
metadata:
  name: frontend
  labels:
    name: frontend
spec:
  ports:
  - port: 8884
    targetPort: 8081
    nodePort: 30080
    name: ui
  selector:
    app: test
  type: NodePort

This frontend service can be accessed by http://node-ip:30080 if run for the first time. What happens if we run the same yaml across different namespace in the same node? How do we resolve this?
