 You can build a local docker image of the testclient using the [`Dockerfile`](../kuksa-client/Dockerfile).
 The Dockerfile needs to be built from the repo root directory.

 - `--rm` ensures we do not keep the docker container lying around after closing kuksa-client and `--net=host` makes sure you can reach locally running kuksa.val-server or kuksa-val docker with port forwarding on the host using the default `127.0.0.1` address.
 - CLI arguments that follow image name (e.g. `kuksa-client:latest`) will be passed through to kuksa-client entry point (e.g. `--help`).
