RancherOS makes it simple to run containers at scale in development, test and production. By containerizing system services and leveraging Docker for management, 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.
