RancherOS

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.

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 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.

Amazon

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.

Google Compute Engine (Experimental)

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.

Download Image

Import

To import the image into your project follow the instructions below:

Usage

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.

Known issues/ToDos

  • Add GCE daemon support. (Manages users)
