CentOS Atomic SIG

SIG Status: Approved

Board Member Helping Bootstrap: KaranbirSingh

The CentOS Atomic Host SIG will work on a CentOS-based Atomic Host image that provides a minimal image using rpm-ostree, as well as tools and documentation for users to create their own CentOS/Atomic images with custom package sets.

1. Goals

• Ship a minimal CentOS Atomic Host that focuses on running Docker containers in production.

• Provide ISO images installable with Anaconda, and images suited for OpenStack, CloudStack, Amazon Web Services/Eucalyptus, and Google Compute Engine.

• Provide tools and documentation that can be used to spin custom images from CentOS packages to be deployed with Atomic (rpm-ostree) tools.
• Provide regular releases as underlying tools (e.g. rpm-ostree) advance, while maintaining stability for in-place upgrades.
• Establish a time-based release cadence.
• All code included in the Atomic image will be under an OSI-approved license.
• Unless differentation is absolutely necessary, all packages common to CentOS core and CentOS Atomic will be identical.

2. Mailing List and Communication

Work for the CentOS Atomic image relevant to CentOS build systems, etc. will take place on centos-devel. Work related to upstream Atomic will take place on the Atomic mailing lists.

Note that the Atomic community comprises efforts underway with CentOS, Fedora, and Red Hat Enterprise Linux, as well as upstreams like Docker and OpenShift (GearD) so discussions may span several communities and mailing lists.

3. SIG Membership

The Atomic Host SIG will have a steering committee and committers. The steering committee now consists of:

• JoeBrockmeier

• JasonBrooks

• Adam Miller

• JimPerrin

• Brian Proffitt

• Greg DeKoenigsberg

• ColinWalters

• Dusty Mabe

New committers and steering committee members are appointed by the steering committee.

Committer privileges, once earned, do not expire unless revoked by the steering committee.

The steering committee will appoint a chair to interface with the CentOS Board.

4. Meetings

The CentOS Atomic SIG will initially meet weekly until all pieces are in place for regular releases, then as needed.

5. Roadmap and (Action) TODO List

• Define package set
• Establish builds for target environments (cloud deployments and bare metal)
• Define orchestration tool(s) for CentOS Atomic
• Establish test / QA processes
• Set long-term release cadence, upgrade policies
