## Overview

- **Who it's for**: System administrators and DevOps teams running containerized workloads at scale, particularly on cloud infrastructure or large server clusters.
- **What you get**: A minimal Linux distribution stripped of package managers and unnecessary userland tools, with applications run exclusively in containers. It provided automatic, atomic OS updates delivered in the background via an active/passive partition scheme, plus built-in clustering support through etcd for distributed configuration and fleet for cluster-wide service scheduling.
- **How it works**: Administrators provisioned machines with Container Linux using a declarative Ignition or cloud-init configuration to set up the base system, then deployed and managed application containers (typically via Docker or rkt) on top, with etcd coordinating cluster state and the OS updating itself automatically in the background. Red Hat ended support for Container Linux in May 2020, with Fedora CoreOS and RHEL CoreOS as successors.
