Container Linux
Container Linux (formerly CoreOS Linux) is a discontinued open-source lightweight operating system based on the Linux kernel and designed for providing infrastructure for clustered deployments while focusing on automation, ease of application deployment, security, reliability, and scalability. As an operating system, Container Linux provided only the minimal functionality required for deploying applications inside software containers, together with built-in mechanisms for service discovery and configuration sharing.

Container Linux shares foundations with Gentoo Linux, ChromeOS, and ChromiumOS through a common software development kit (SDK). Container Linux adds new functionality and customization to this shared foundation to support server hardware and use cases.: 7:02 CoreOS was developed primarily by Alex Polvi, Brandon Philips, and Michael Marineau, with its major features available as a stable release.
The CoreOS team announced the end-of-life for Container Linux on May 26, 2020, offering Fedora CoreOS, and RHEL CoreOS as its replacement, both based on Red Hat Enterprise Linux.
