Step 2: Changing Service §

Currently, I have a NodePort service set up for my deployment. I’ll modify this service to be a ClusterIP type, which is only accessible within the Kubernetes cluster.

I use the kubectl edit command to modify the service configuration directly:

kubectl edit service

This command opens the service’s configuration in an editor. Within the editor, I perform the following changes:

1. Change the type field from NodePort to ClusterIP.
2. Set the nodePort field to null or remove it entirely, as ClusterIP services do not require an external port.

After:

I verify the change by inspecting the list of services with the command kubectl get svc. In the output, I confirm that my service, my-nginx-service, now shows ClusterIP in the TYPE column. %%previous%%

Success

To quickly test the ClusterIP service, I use the curl command to send a request to the service’s IP address from within the cluster (master node) :
