R Banerjee:
Nodeport is the port on the node( i.e. the machine where the pod is deployed)
Think of it like the ISP port. When we talk to a machine on the internet, the message goes from our computer( pod’s target port) , to the our home router ( service’s port), to our Internet-Service-Provider’s port( node-port), and then to the outside network
