Brian "bex" ExelbierdIf you’re in Prague this weekend and care about practical Linux ops, I’m doing two talks at Installfest.cz on Saturday (building A, CTU FEL, Karlovo náměstí), both in English:
15:30–15:55 (Track II) – You Don’t Need Kubernetes: Side Projects on One Linux Server
17:00–17:25 (Track III) – Flatcar Linux 101: A Hands-Free Server OS

You Don't Need Kubernetes: Side Projects on One Linux Server Installfest 2026
You probably do not need Kubernetes, a dedicated secrets vault, or Grafana to run a small side project on the internet. In this talk, I show how I run a reliable web service on a single immutable Flatcar Linux server with rootless Podman containers managed by systemd. I also explain how I reuse 1Password for secret injection and Home Assistant via MQTT for simple monitoring. The goal is a practical, repeatable setup you can run at home and mostly ignore between feature updates. This talk is for developers and homelab enthusiasts who want to run reliable services without spending all their time on maintenance.
For a fireside chat with creators and maintainers of #SpecialPurposeOS #Linux distributions like #Flatcar or #Kairos at #FOSDEM, please drop by our SPOS BOF Session: Today (Saturday) 5pm in K4.401.
No matter whether you're curious, a user, or a maintainer - drop by and join us!
(Also, please boost!)

Flatcar Container Linux 🚂
🌅 New day, new Flatcar releases!
Alpha 4515.0.0, Beta 4459.1.1, and Stable 4459.2.0 are out with Linux 6.12.54, cgroups v1 kernel config mitigations, and major security updates across the stack.
I rarely talk about work here, but this took quite some effort of the team and fellow maintainers:

Today, we add #Azure #AKS to our list of hosted #Kubernetes offers that support #Flatcar #Container #Linux. It's not the first, and it sure won't be the last. Documentation is here: https://learn.microsoft.com/en-us/azure/aks/flatcar-container-linux-for-aks
ck@jasondmoss Thanks, but I'm switching my new hardware to #flatcar, I'm tired of dealing with this stuff again and again.
