what is the difference between nodePort, port and targetPort

#2

Hello,

  • nodePort : The port on the node where external traffic will come in on
  • port : The port of this service
  • targetPort The target port on the pod(s) to forward traffic to

Traffic comes in on nodePort , forwards to port on the service which then routes to targetPort on the pod(s).
