@rainahtdm
Did you ever get an answer to your question? I am also doing the Kubernetes for beginners course and have just run into the exact same problem.

Any input is appreciated.

Thanks
Sujit

Hello, @sujitkcloud
Can you please tell me where you’re performing?

@Tej-Singh-Rana,
I a in the middle of doing the K8s for absolute beginners course, and trying to practice the demo steps on my local machine, using minikube on Windows 10 using Docker.

Scenario 1: When minikube generates the service url, it provides the url as a loopback url with a random port.
e.6 127.0.0.1;65237.

I am using Windows Powershell terminal to complete the tasks, and leave the 2 powershell windows open
I am able to test out the application successfully.

Scenario 2:
I also tested this on a different "ubuntu’ system, where I installed minikube using VirtualBox and the service URLs generated correctly, using NodePort configuration.

My question is for Scenario1 above.
How can I fix the Minikube/docker environment to utilize the NodePOrt configuration when generating the minikube service URL?

Thanks in advance for your input
Sujit
