Fast, ultra-lightweight container OS

RancherOS makes it simple to run containers at scale in development, test and production. By containerizing system services and leveraging Docker container management tools, the operating system provides a very reliable and easy to manage container-ready environment.

System services are defined by Docker Compose and automatically configured using cloud-init, reducing administrative burden. Unneeded libraries and services are eliminated, resulting in a significantly reduced footprint and minimizing the hassle of updating, patching and maintaining a container host operating system.
