  # Listen on ports 5000 and 6000 locally, forwarding data to/from ports 5000 and 6000 in a pod selected by the deployment
  kubectl port-forward deployment/mydeployment 5000 6000
  # Listen on port 8888 locally, forwarding to 5000 in the pod

I have a feeling this landed in #13, and happens for all with kubectl version <= 1.13.0, see kubernetes/kubernetes#40053 (comment)

@sandratatarevicova do you think this is something we want to fix for low kubectl versions?

[sandratatarevicova]

I think we should detect kubectl version and use the --address flag only for version 1.13.0 and higher (see kubernetes/kubernetes#46517 (comment)).
