The Atomic Host platform is now replaced by CoreOS. Users of Atomic Host are encouraged to join the CoreOS community on the Fedora CoreOS communication channels.

This release of Atomic App introduces a large code-base change related to our Kubernetes provider.
We incorporate major changes to the Kubernetes provider. With this release, we replace the usage of kubectl with the requests Python library and the Kubernetes HTTP API end-point. This change results in faster deployment, smaller image sizes, and increased detail in logging messages.
The main features of this release are:
This week was the Fedora Cloud Working Group’s Activity Day
(FAD), where a dozen of us got together to work on the project’s adoption and innovation in the public and private cloud sectors. Discussions and decisions there covered a range of topics, including Fedora Atomic Host, public cloud images, Vagrant improvements, and automated testing of cloud base images, Atomic and container images. You’ll be seeing a bunch of changes resulting from this over the coming months.
One topic came up which is going to pretty much eat my time for at least a week, though: we don’t yet have a working, easy-to-deploy download of OpenShift Origin on Fedora Atomic Host. Clearly, we need to fix this; my goal is to have something working by this time next week, for DockerCon.
While a lot of people use Atomic Host and OpenShift on public clouds, one of the ideas behind Project Atomic is to enable you to create your own container cloud. So for both testing and demos, we needed a container stack on real hardware,
letting us test things like bare-metal deployment, Foreman integration, power-loss failover, and high availability in general. And this cluster needed to be small enough to bring with us to events. Given that, introducing the Sub-Atomic cluster:
In this week’s release of Atomic App we not only have cleaner logging output when using the tool, but we’ve also added binary generation!
The main features of this release are:
atomicapp initWhat the heck is commissaire? I’m glad you asked! Commissaire is a new component of Project Atomic that aims to simplify life for cluster administrators. It provides a simple, script-friendly REST interface for cluster-wide maintenance operations like system upgrades and rolling restarts.
Instead of starting from scratch, Commissaire utilizes common technologies such as Ansible for communicating with cluster nodes, and interfaces with OpenShift and Kubernetes.
