update-alternatives for python3 on Ubuntu

Ubuntu 20.04 Playing with Python versions

Loads of solutions exist, but for changing the system default, alias is not the way to go.

K8s on Raspbian

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.

Pre-reqs:

  • 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)

Master node setup

How to write an image file to an SD card under Mac OS X (for Raspberry Pi)

Find the SD card device

In this case, the SD card is /dev/disk4. DO NOT get this wrong or you may destroy all the data on the wrong disk/card/drive.

diskutil list

/dev/disk0
