K8s on (vanilla) Raspbian Lite

Yes - you can create a Kubernetes cluster with Raspberry Pis with the default operating system Raspbian. Carry on using all the tools and packages you're used to with the officially-supported OS.

Pre-reqs:

• You must use an RPi2 or 3 for Kubernetes
• I'm assuming you're using wired ethernet (Wi-Fi also works)

Ansible execution begins with the script: `bin/ansible`. This script is sym-linked to other names, such as ansible-playbook and ansible-pull, ansible-conneciton being the exception.

When executed, this script looks at the first parameter passed to it. On Linux/Unix systems, this parameter is the name of the script itself. By examining this value, we can determine which CLI class we should load and execute.

Ansible CLI Classes:
- AdHocCLI (the plain "ansible" command)
- PlaybookCLI (when run with "ansible-playbook")
- PullCLI (when run with "ansible-pull")
- DocCLI (when run with "ansible-doc")
- GalaxyCLI (when run with "ansible-galaxy")
