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         


        

Answer 1

I had the same problem and the only way I found to do it without modifying the files was:

k expose --type=NodePort deployment nginx --port 80 --name nginx-ep-patch  --overrides '{ "apiVersion": "v1","spec":{"ports": [{"port":80,"protocol":"TCP","targetPort":80,"nodePort":30080}]}}'
service/nginx-ep-patch exposed

In this way we path online the configuration and the port 30080 has been exposed:

$ k describe svc nginx-ep-patch
Name:                     nginx-ep-patch
Namespace:                default
Labels:                   app=nginx
Annotations:              
Selector:                 app=nginx
Type:                     NodePort
IP:                       10.96.51.148
Port:                       80/TCP
TargetPort:               80/TCP
NodePort:                   30080/TCP
