How should I set up my development environment (which tools, CI etc.) to be able to build functional "local" versions of the pkgs like kubelet used in this project? - If I simply build the kubelet pkg using 'docker build .' , put its id into yml/kube.yml and build new image it seems that the files and folders like '/var/lib/kubeadm' which are created by other service containers are not visible.

I'd be happy to help on fixing issues like #71 and #72 but first I need to get a working development environment. :)
