I wanted to expose my application on all the ports between 3000-14000. For this, I have changed the default nodePort range 30k - 32767 by updating kubeapi-server manifest file field "--service-node-port-range=3000-14000". For me, it is almost impossible to expose by specifying all the port numbers manually following the below template.
apiVersion: v1
kind: Service
metadata:
name: myapp-service
spec:
type: nodePort
selector:
app: myapp
ports:
- targetPort: 3000
port: 3000
nodePort: 3000
...................
...................
- targetPort: 14000
port: 14000
nodePort: 14000
Do we have any other alternative solution/plugins to this, so as to open all ports between the range 3k - 14k.
Well based on the comments this is just the same as having 11k app (sic!).
So you have to do it the "normal" way I suppose... meaning you have to map all your 11k port manually.
However, in order to make it less painfull, you can omit the nodePort attribute. Kubernetes will automatically assign one that is not used.
Unfortunately Kubernetes doesn't yet support exposing range of ports (it's possible in Docker).
As a workaround use Helm templates to create chart with service template and ports in values.yaml file. Or create a script to automate creation of a service yaml to expose each port.
