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 to about 20MB. Everything else can be pulled in dynamically through Docker.
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 PID 1. 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.

We have 2 different virtualization types of AMIs. SSH keys are added to the rancher user, so you must log in using the rancher user.

We are providing a disk image that users can download and import for use in Google Compute Engine. The image can be obtained from the release artifacts for RancherOS v0.3.0 or later.
To import the image into your project follow the instructions below:
The image supports RancherOS cloud config functionality. Additionally, it merges the SSH keys from the project, instance and cloud-config and adds them to the rancher user.
- Add GCE daemon support. (Manages users)
Please refer to our website to read all about RancherOS. It has detailed information on how it works, getting-started and other details.
