Kairos has always been more than just a Linux distro—it’s a bold idea: bring the power and flexibility of Kubernetes to the edge, with a truly immutable, secure, and cloud-native operating system anyone can use, contribute to, and trust. Over the past few years, we’ve seen Kairos go from idea to implementation, and from experimentation to production. Today, it’s running in large-scale, real-world deployments across diverse edge use cases. But more importantly—it’s been growing as ...| kairos.io
Introducing the new CLI-driven system extension management in Kairos. Download, enable, and manage system extensions live without rebuilding your OS image.| kairos.io
Up until now, Kairos has shipped with first-class support for k3s out of the box. If you wanted something else? You had to rely on community-powered providers. And let’s be honest, while amazing in their own right, they’ve been… fragmented. We’ve seen providers emerge for kubeadm, nodeadm, microk8s, and even another flavor of k3s. Each one added the ability to run Kubernetes on Kairos, but they were often self-contained efforts. Most didn’t plug into our cloud-init-style configurati...| Kairos
🧱 Introduction Building Kairos has always been about more than assembling images — it’s about shaping a flexible, powerful OS tailored for the edge. Over the past couple of years, we’ve learned a lot while navigating how to build and maintain Kairos across a growing list of base distributions, architectures, and board-specific targets. Today, we’re excited to introduce something that marks a turning point in how Kairos is built: kairos-init.| kairos.io
Picture this: You’re deep in focus, coding away, and the doorbell rings. Except… you never hear it. The mailman leaves, and now your package is on an adventure you didn’t plan for. That’s exactly what happened to me, so I did what any geek would do—turn my dumb doorbell into a smart one using Kairos.

We’re thrilled to announce that since April 2024, Kairos has been officially part of the Cloud Native Computing Foundation (CNCF) as a Sandbox Project. This marks an important milestone for Kairos and, more importantly, for our entire community of users and contributors. You might be wondering - what does being part of the CNCF mean for you? The CNCF is known for backing the most innovative, reliable, and secure projects in the cloud-native space, and having their support brings a number of...| Blog on Kairos
I can’t believe it’s already October. I’ve been so busy following up on different events where we’ve brought some of the Kairos love that I forgot about Hacktoberfest. Thankfully, the month isn’t over so let’s get our hands dirty! Like last year Kairos is taking part in this event. This means that you can open PRs in any of our repositories, and we’ll make sure to tag them correctly so they count towards your progress (please contact us if this is not the case).| Blog on Kairos

The recent CrowdStrike update fiasco that wreaked havoc across industries, causing BSODs and crippling critical systems, starkly highlights the need for resilient and immutable infrastructure. If affected organizations had adopted an immutable OS like Kairos, their systems would have shown greater resilience against such widespread disruptions. TL;DR CrowdStrike’s faulty update led to massive system crashes. Kairos’s immutable and decentralized architecture offers a robust alternative, en...| Kairos - The immutable Linux meta-distribution for edge Kubernetes

In the evolving landscape of cybersecurity, protecting the integrity of computing systems from the moment they power on has become very important. As threats become more sophisticated, understanding and implementing advanced boot security mechanisms like Trusted Boot, Full Disk Encryption (FDE), Secure Boot, and Measured Boot are critical for safeguarding data and ensuring system integrity. This article demystifies these concepts, explores their significance, and examines their implementation...| kairos.io
It’s all over the tech news. Someone managed to put a backdoor on xz Utils, a very common package on Linux systems. In this post I want to share with you about what happened, how it impacted Kairos images, and what you should do in case you were affected. TL;DR A backdoor that can be used to exploit systemd based Linux via ssh was introduced in xz Utils. Only Kairos Tumbleweed v3.| kairos.io
I recently had the opportunity to attend KubeCon 2024. You can find my recap at the Spectro Cloud Blog, but I’d like to add some additional information about the Special Purpose Operating System Panel in which we participated. The panel was scheduled for the last day of KubeCon, which I think probably hurt the attendance since many people had already left. Nevertheless, according to the scheduling tool, 351 people were planning to attend.| kairos.io

Last year I said you could expect Kairos to engage further during FOSDEM. And I’m quite pleased to say that’s exactly what we did! As part of the open-source ecosystem, we recognize the importance of participating in these types of events. We do so, because we understand how critical it is to go where our users are, but this year we went a bit further and we also reached out to other similar projects.| kairos.io

Hacktoberfest 2023 is here, and we are excited to announce that Kairos is taking part by creating some good first issues for new contributors to get started with and also by hosting a Hacktoberfest event on October 19th in Brussels. Why is Hacktoberfest important to us? We believe in open source, this is why all of Kairos’ source code is fully open-sourced, but our commitment doesn’t stop there, we also want to help developers, students and anyone interested to learn more about open sourc...| kairos.io

The problem You got yourself a Rabserry Pi (or more), and you want to put them to good use. You decide to make a Kubernetes cluster out of them, so that you can utilise the resources better, use familiar tools and implement infrastructure-as-code. Up to this point, kudos to you for demanding no less than a real cloud from your home infra. Like a smart person you are, you probably used Kairos to create your cluster and it’s now up and running.| kairos.io

We recently had the opportunity to sponsor two Kubernetes events, KCD Amsterdam and KCD Paris. This blog post, is a summary about my personal experience attending them. Let me start by saying, that I’m fairly new to Kubernetes and its community 👋. I know this project is big and that there are many companies building products and services around it, or have an interest in adopting it. So, I was very curious to see what kind of people I was going to meet and understand how Kairos could hel...| kairos.io
