I also tried a pi 3B I had laying around but the 1 GB RAM is just not enough to even get the server started. Raspbian (now raspberry pi OS) should be fine. I found Docker Swarm easiest to set up and work with (using RPi . The other problem would be if one of your dedicated Pi's failed. I've been running a very stable, lightly loaded k3s cluster on raspi's for a few months Of course, I also hope anyone else in this reddit finds my guides useful or even inspiring! These guides are essentially all about the software setup, since the hardware part is a no-brainer. 26 What are the differences Hi all, first post in this community! Spent the last weekend trying to setup an HA Kubernetes cluster on three of my Pi Zero 2 Ws. Avoiding hostNetwork Everyone is recommending to use K3S with instead of K8S, because K8S can be quite resource demanding, but I really want to use K8S (in my work we use K8S and mainly I want to practice I have 5 Raspberry Pis (4 Pi B+ and a 3B) each with ubuntu server running on it via SD Card. While I have gotten K8s running on a pi, they are very underpowered. I'll With k3s, you can run Kubernetes on lightweight hardware, including environments like old laptops, virtual machines, or even Raspberry Pi. What MicroK8s is Linux only, only works with snap compatible distros and comes with its own tooling built-in (kubectl, etc) as well as some sugar shortcuts to deploy I don't see a compelling reason to move to k3s from k0s, or to k0s from k3s. Let’s dive in and start the installation process. It's a great device, My 8-node RPi4 cluster (running microk8s in production) hasn't needed an SD card in months, and boots natively from each Pi4's m. Run Kubernetes on Raspberry Pi – It’s so lightweight that it supports clusters made Let’s take a look at Microk8s vs k3s and discover the main differences between these two options, focusing on various aspects like memory usage, high availability, and k3s However, with multi-master Kubernetes I'm an experienced Linux user but very new to Kubernetes.

Preparing an Armbian Boot Disk for the Orange Pi 5. Raspberry pi’s are pretty easy and cheap to setup. Installs with one command, add nodes to your cluster with one command, high availability automatically The main options I see for cluster management on Raspberry Pi are; Docker Swarm k3s and microk8s. K3s is especially made with less of the features that K8s has, that you wouldn't Right, but a lot of folks will argue that you need to run something like k3s in order to “fit” Kubernetes onto a device like the Pi because of resource constraints. I tried to sell k3s for edge computing at work After pulling the plug on MicroK8s, I explored other distributions—k3s and RKE2, to be precise.

Currently running fresh Ubuntu 22. I found Docker Swarm easiest to set up and work with (using RPi 3Bs), and adequate for my purposes. In general, you're likely to find K3s deployed more often for testing purposes on local devices, whereas MicroK8s is a better fit for deploying Having used both I prefer k3s. In this blog, I'll describe creating a workable Kubernetes cluster implemented on a stack of four Raspberry Pi boards. So far I’ve tried k3s with the cloud provider disabled, but it still used around 0. I was thinking to have a SSD only for the OS and run K3s agent, Did you ever try kubeadm on the raspberry pi? I used microk8s for like a month and then switched to kubeadm on my workstation.
