Development and Maintenance Status

RancherOS 1.x is no longer being actively maintained. There are two significant reasons behind this product decision: 1. Docker - The current industry requirements for a container runtime are very much evolving. Container runtimes like containerd and CRIO are now being actively considered as the default choice. RancherOS 1.x, which was specifically designed around using Docker engine only, unfortunately does not lend itself, in its current design, to this new evolving requirement. 2. ISV Support - RancherOS was specifically designed as a minimalistic OS to support purpose-built containerized applications. It was not designed to be used as a general purpose OS (such as CentOS or Ubuntu). As such, most ISVs have not certified their software to run on RancherOS, nor does RancherOS even contain the necessary components for many of these applications to run.

We're working on a replacement. Stay tuned!

RancherOS

Build Status Docker Pulls Go Report Card

The smallest, easiest way to run Docker in production at scale. Everything in RancherOS is a container managed by Docker. This includes system services such as udev and rsyslog. RancherOS includes only the bare minimum amount of software needed to run Docker. This keeps the binary download of RancherOS very small. Everything else can be pulled in dynamically through Docker.

How this works

Everything in RancherOS is a Docker container. We accomplish this by launching two instances of Docker. One is what we call the system Docker which runs as the first process. System Docker then launches a container that runs the user Docker. The user Docker is then the instance that gets primarily used to create containers. We created this separation because it seemed logical and also it would really be bad if somebody did

docker rm -f $(docker ps -qa)
and deleted the entire OS.
