Deploy K3s and Rancher on Raspberry Pi 4 cluster

Today I tried to setup a small Kubernetes cluster on top of 3 Raspberry Pi 4 (4GB Memory). Here is the steps to install the cluster.

Preparation

I have 3 Raspberry Pi 4 stacked with PoE headers and connected to a PoE switch at home. The are connected to Internet through a home router. All Pis are equipped with a 64GB Samsung SDXC card flushed with Ubuntu 20.04 image.

	# Add to your `.zshrc` file or use the function's contents as a script.
	#
	# With the former, add the function, restart your terminal, connect
	# a USB serial device, eg. a Raspberry Pi Pico, and then enter `dlist`
	# at the command line.
	#
	# You should see something like this:
	# `/dev/cu.usbserial-01AB8E0B`
	#
	# If you have only one device attached, you can include the function's

	const app = Application.currentApplication()
	app.includeStandardAdditions = true

	function getJSON(path) {
	const fullPath = path.replace(/^~/, app.pathTo('home folder'))
	const contents = app.read(fullPath)
	return JSON.parse(contents)
	}

	function run() {

	#Install WinGet
