Imagine an OS that works as hard as you do - streamlining your infrastructure, reducing costs, minimizing operational overhead, and securing your workloads. Flatcar is engineered for teams that value efficiency, resilience, and peace of mind.

Flatcar Container Linux, a Cloud Native Computing Foundation (CNCF) incubating project, is a secure, minimal, and an operating system built from the ground up to run container workloads at scale. It fully embraces the container paradigm - delivering only what’s needed to run containers and nothing more.

Immutable Infrastructure
Your infrastructure is immutable - your OS should be too. Flatcar features a read-only /usr filesystem, drastically reducing the attack surface and ensuring consistent, repeatable deployments.
Minimal & Focused
With containers packaging all dependencies, there's no need for a package manager. Flatcar eliminates OS bloat and configuration drift, offering only the essentials needed to run containers.
Effortless, Automated Updates
Flatcar provides an atomic, hands-free updates with rollback support - keeping your systems secure without manual intervention.
Designed to Scale Built with tools to manage large-scale, global infrastructure and manage / update polices, versions and group instances with ease.
Reduced Complexity
With no traditional package manager and fewer moving parts, Flatcar simplifies your base OS while containers handle the rest.
Modular extensions with sysext Supports systemd-sysext aka system extensions to layer in additional functionality without modifying the base OS.

Launch Flatcar on Azure for a lean, secure, and production-grade OS purpose - built for containers and modern infrastructure.
