  • Product: Atomic Cloud Image (duh!)
  • Responsible WG: Cloud

Current status

  • Targeted release: Fedora 21
  • Last updated: 2014-07-10
  • Tracker bug: <will be assigned by the Wrangler>

Presently, a compose server has been set up, and is composing trees. The content is rsync'd to This server is running an instance of which generates trees and disk images.

Detailed Description

This could be thought of as a Fedora instance of the Project Atomic pattern, oriented for cloud usage. The name of the product will be "Fedora Atomic", because future iterations will support bare metal installation.

A major difference with traditional Fedora projects is this will use rpm-ostree technology to do atomic updates of the host system.

The goal is to come with Docker ready to go out of the box.

Benefit to Fedora

Containers are a powerful and flexible way to deploy and manage server applications, with numerous benefits such as density, ease of deployment, and orchestration. In concert with Changes/Docker_Container_Image, this will allow running Fedora content in containers and on the host system. The same RPM content will go into both.


  • Proposal owners: Currently generating trees on a compose server and syncing them.
  • Other developers: N/A (not a System Wide Change)
  • Release engineering: Will need to generate trees during the general Fedora compose process, and generate install media and cloud image based on trees.
  • Policies and guidelines: N/A (not a System Wide Change)

Contingency Plan

If any of the bonus objectives fail to make it in time, we simply go on without them and use the established mechanisms (i.e. what F20 did or what the F21 Fedora Base Cloud Image does) instead.

If all fails, there simply won't be a Fedora Atomic Cloud Image product for F21.

  • Blocks product? Yes, Atomic Cloud Image (duh!)

Release Notes

New Fedora product: Fedora Atomic Cloud Image, featuring Docker and tools from Project Atomic.

Docker is an easy to use interface for running application containers on Linux. Fedora is uniquely positioned to provide the best platform for Docker, since this container technology is not a security solution, but can be made reasonably secure when wrapped with SELinux.
