In this post we'll test-drive k3s which is a stripped-down Kubernetes distribution from Rancher Labs. With a single binary and a one-line bootstrap process it's even easier than before to create a light-weight cluster. So grab your Raspberry Pi and get ready to deploy the smallest Kubernetes distribution ever k3s-setup-on-raspberry-pis. Initial raspberry Pi setup using k3s.io -- Kubernetes cluster on raspberry pi 3s! Prepare the Pis. Install Raspbian Lite to the SD card with Etcher. Be sure to place a file named .ssh onto the SD card. SSH into the Pi (username: pi & password: raspberry) and type Among this, K3S is recently released and got huge attention. It is a lightweight and certified Kubernetes distribution and can run on many low-end devices like Raspberry Pi. For this article, we are going to use K3S. We will explore KudeEge and MicroK8s later. In this article, we will explore how to create a bare minimum cluster using 3 Raspberry Pis, one master, and two worker nodes. I am using Raspberry Pi 4 as a master and 2 Raspberry Pi 3 as worker nods. But you can choose whatever. K3s is billed as a lightweight Kubernetes for use in resource-constrained environments. It is also optimized for ARM processors. This makes running a Raspberry Pi-based Kubernetes cluster much more feasible. In fact, we are going to create one in this article about a year ago k3s raspberry-pi I downloaded Raspbian Buster Lite from the official site and wrote it to the SD cards (using dd). Then I configured the card for headless SSH access (touch.../boot/ssh). Then, one at a time, for each Raspberry Pi, I put the SD card in each Raspberry Pi and turned it on
Kubernetes RaspberryPi K3S. RaspberryPi 4.

K3s comes with a default Local Path Provisioner that allows creating a PersistentVolumeClaim backed by host-based storage. This means the volume is using storage on the host where the pod is located. Let's.
The longer answer is that K3s has everything you need for your Raspberry Pi from Kubernetes. It was developed for small servers without all of the unnecessary extras that Kubernetes has. This allows the memory footprint to be smaller on your Raspberry Pi and uses less than 40mb of space on your SD card so no wasting space We choose to run k3s on a cluster of 3 Raspberry Pi nodes composed of 1 master node and 2 slaves nodes. To show the use of our agent we decided to run different apps: a load generator to observe the impact of charge on our cluster thanks to the Bleemeo agent and Quote a little app run on Nginx and PostgreSQL. This first article is dedicated to assembling the Raspberry Pi cluster and deploying. Uninstalling K3s deletes the cluster data and all of the scripts. To restart the cluster with different installation options, re-run the installation script with different flags. To uninstall K3s from a server node, run: /usr/local/bin/k3s-uninstall.sh To uninstall K3s from an agent node, run: /usr/local/bin/k3s-agent-uninstall.s
