Service Reference Guidelines
1. Port vs TargetPort
port exposes the service inside the cluster network, whereas targetPort represents the actual port the containerized application is listening on.
2. Service Type Selections
Use ClusterIP for internal microservice communication, NodePort or LoadBalancer when traffic needs to originate from external clients.
