Atomic Host

Based on proven technology either from Red Hat Enterprise Linux or the CentOS and Fedora projects, Atomic Host is a lightweight, immutable platform, designed with the sole purpose of running containerized applications.

To balance the need between long-term stability and new features, we are providing different releases of Atomic Host for you to choose from.

Atomic App and Nulecule

With Atomic App, use existing containers as building blocks for your new application product or project. Using existing containers to provide core infrastructure components lets you focus more on building the stuff that matters and less time packaging and setting up the common plumbing required.

Define your Atomic Apps with the Nulecule specification to compose and distribute complex applications.

Docker Brno—Back in the Saddle Again

On the 15th of June, over 60 brave souls gathered together and in defiance of an absolutely gorgeous summer day, talked about containers. Four speakers presented a very different set of talks covering all areas of containers from development to management to deployment.

Jiří Sedláček, an agile QA specialist and developer at Wandera, presented “Development and Deployment Simplification with Containers” (slides). At a previous company, he and the team implemented a docker-driven development environment that helped change the operational philosophy from the bottom up.

Atomic Registry Deployment Update

Since Atomic Registry was announced as the enterprise, 100% open source private docker registry, we have been responding to feedback from the community to make it great. The Cockpit team has been working hard to improve the console interface and general user experience. The OpenShift team has been tirelessly updating the backend to make the registry more stable, usable, and easier to deploy and maintain.

Some of the feedback we received suggested the deployment method was difficult to understand. As part of OpenShift it pulled in a lot of dependencies that were not essential for running the registry. The OpenShift features are terrific for running clustered container workloads but it can be a barrier to some administrators for just running a standalone registry.

Building a Sub-Atomic Cluster, Part 2

I’m continuing to kit out the Sub-Atomic Cluster, in the process it’s received some upgrades. Thanks to John Hawley of the Minnowboard Project at Intel, I now have a nice power supply instead of the tangle of power strips, and in a couple days I’ll also have more SSD storage. You can see here that one node is in a nice blue metal case: that’s Muon, which we’ll be raffling off at DockerCon. Come by booth G14 to see the cluster and for a chance to win the Muon!

While I’m waiting for those, though, I might as well get this set up as a proper Kubernetes cluster. Ansible is my tool for doing this.

Atomic App 0.6.0 Released—Native Kubernetes API Integration

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:

  • Kubectl to API conversion
  • Removal of ASCII art
