KubePi

This repo is currently considered to be a dumping ground for all the things I want to try out with my Raspberry Pi cluster which ultimately should run Kubernetes and a couple of containers at home. Besides that I want to try out a couple of other things like Ansible and stuff.

I did not come up with all this by my own. Please refer to Alex Ellis k8s-on-raspbian repo for setting up Kubernetes on Raspbian and the rak8s repo for setting up Kubernetes on Raspian with Ansible.
