kgrok my-svc localhost:8080

We assume you have a service already listening locally on port 8080 and you have your kubectl context configured for the cluster you want to listen receive traffic from.

Using pipx might be the most reliable.

pipx install kgrok

If you are however already in a Python 3.12 virtual environment, or inside a container with pip, you can probably get away with it.

python3 -m pip install kgrok
