Make arm64 deb packages for the offical Raspberry Pi Foundation arm64 kernels, tested with ubuntu 23.04
#!/bin/bash -x
# make_arm64_rpi_kernel_debs.sh
# Builds arm64 debian packages from the CURRENT rpi firmware repository kernel which is installed by:
# sudo rpi-update
# This runs on an arm64 host with arm64 compilation tools...
# or with some sort of cross-compilation setup.
# Debs are put in $workdir/build
#
# This will NOT work in Raspbian unless you have an arm64 compilation
# environment setup. Appears to work on

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.
