Kubernetes on (vanilla) Raspbian Lite
Yes - you can create a Kubernetes cluster with Raspberry Pis with the default operating system called Raspbian. This means you can carry on using all the tools and packages you're used to with the officially-supported OS.
- You must use an RPi 2 or 3 for use with Kubernetes
- I'm assuming you're using wired ethernet (Wi-Fi also works, but it's not recommended)
