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.

Get Started

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.

Contribute to the Atomic Host Documentation!

Project Atomic is changing rapidly and documentation needs to follow the pace of development. That’s why we need your help!

The new documentation is going to be maintained through the Atomic-host-docs repository, which uses AsciiDoc as markup language and AsciiBinder to build the documentation pages. More importantly, AsciiBinder will allow us to produce both Fedora Atomic and CentOS Atomic documentation from the same source repository using a concept called distros.

Our plans for the documentation include a complete revamp of the current pages, per our outline in the repo. The Atomic Host docs should eventually completely cover installation and setup, quickstarts for trying it out, deployment of Kubernetes and/or OpenShift clusters, and how to compose your own OStrees and deployment.

That’s where you come in. We need help writing docs, and converting docs and blog posts from other sources into the new documentation structure. Read further for how to set up for a doc build.
