What is Flatcar Container Linux?
Flatcar Container Linux is a minimal, immutable, container-optimized Linux operating system and the active successor to CoreOS Container Linux. It is designed to run container workloads consistently across cloud providers, virtualization platforms, and bare-metal environments.
Flatcar ships only the essentials needed to run containers — no package manager, no configuration drift. Its immutable, read-only filesystem minimizes attack surfaces, and atomic, automated updates keep your system secure and up-to-date without manual intervention.
Unlike general-purpose distros, Flatcar has no package manager (apt, yum, etc.) and its root filesystem is read-only. You declare the state you want at boot time (via Ignition) and the OS atomically applies it. Updates happen automatically in the background and take effect on the next reboot — no manual patching required.
