@mbohlool Please, why does the documentation (https://github.com/kubernetes-incubator/client-python/blob/master/kubernetes/docs/V1ServicePort.md) say target_port is of type str, but when I do target_port='9376' I get the errors below.
kubernetes.client.rest.ApiException: (422)
Reason: Unprocessable Entity

Ignore docs and pass a number instead of string. Let me know if it worked and I will explain why.

Thanks, passing a number works fine.

| "A Service in Kubernetes is a REST object, similar to a Pod. It is an abstraction which defines a logical set of Pods and a policy by which to access them - sometimes called a micro-service." |

A service is a key Kubernetes API resource. It defines a networking abstraction to route traffic to a particular set of Pods using a label selection.

..the label selection allows Kubernetes to determine which Pod should receive traffic when the service is used.
