-To setup a port-forward, you will need to navigate to the PodView, select a pod and a container that exposes a given port. Using `SHIFT-F` a dialog comes up to allow you to specify a local port to forward. Once acknowledged, you can navigate to the PortForward view (alias `pf`) listing out you active port-forwards. Selecting a port-forward and using `CTRL-B` will run a benchmark on that HTTP endpoint. To view the results of your benchmark runs, go to the Benchmarks view (alias `be`). You should now be able to select a benchmark and view the run stats details by pressing `<ENTER>`. NOTE: Port-forwards only last for the duration of the K9s session and will be terminated upon exit.

 These rules below are just suggestions. You will need to customize them based on your environment policies. If you need to edit/delete resources extra Fu will be necessary.
