How to set service-node-port-range and then be able to deploy services using the new port range?

I have a requirement that a test server should use the port range 20000 - 22767

kubectl edit cm

Answer 1

It is possible to update the service-node-port-rangefrom it's default values.

I updated the file /etc/kubernetes/manifests/kube-apiserver.yaml with --service-node-port-range=20000-22767.

The apiserver was restarted and the port range was updated.

I wrote a blog post about it.
