  1. You could have multiple services, one for each port. As you pointed out, each service will end up with a different IP address
  2. You could have a single service with multiple ports. In this particular case, you must give all ports a name.

For some Services, you need to expose more than one port. Kubernetes lets you configure multiple port definitions on a Service object. When using multiple ports for a Service, you must give all of your ports names so that these are unambiguous. For example:

How to work with command line?
