Os
Rancher OS is a cloud-native, container-optimized Linux distribution designed to host and manage containerized workloads with a small host footprint. It functions as a Docker-based operating system that runs core system services and user applications as containers.
The system implements an immutable infrastructure workflow by deploying the entire operating system as a set of read-only images. To prevent configuration drift and ensure a consistent boot state, the primary system partition is mounted as read-only, while persistent settings and user data are stored on a separate writable configuration volume.
The distribution is designed for rapid provisioning across major cloud providers, establishing lightweight hosting foundations for containerized services.
