Current status

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

There are two major delivery aspects to Atomic; the host (this change) and the container: Changes/Docker_Container_Image.

The host system will use rpm-ostree technology to do atomic updates of the host system. This is distinct from the traditional Fedora package manager.

In this instance, the host system is only targeted for cloud providers.

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.
