K8s version 1.12.1 can't be installed on a RPi - trying older versions of kubeadm and docker-engine

readme.md

K8s on RPi

All credits go to @alexellis and his description.

I don't want to duplicate the blogpost but I am not able to get K8s running on my RPi 3 at all. So far I have tried to install those versions:

• 2018-10-09-raspbian-stretch-lite.zip
• docker 18.06.1-ce
• k8s 1.12.1

But this combination is not working at all for me. I have the exact same error.

For me this version is working. So right now I am only trying to find a working combination and want to share my experiences with the communnity. Maybe those scripts get obsolete with a new version of k8s. We will see...
