How to expose a Kubernetes service on a specific Nodeport?

Question

I have create a pod with the below yaml definition.

apiVersion: v1
kind: Pod
metadata:
  name: myapp-pod
  labels:
    app: myapp
spec:
  containers:
  - name: m

If your cluster does not have a LoadBalancer Provider, you can specify externalIPs in IP of nodes' network interface.

For example:

apiVersion: v1
kind: Service
metadata:
  name: nginx
spec:   
  type: ClusterIP
  externalIPs:
    - 125.100.99.101 # Node1-IP
    - 125.100.99.102 # Node2-IP
    - 192.168.55.112 # Node2-IP2
  selector:
    pod: nginx
  ports:
    - name: http
      port: 80      
    - name: https
      port: 443      

This will listen 80 and 443 on the specified node, and forward to the nginx service.
