This document represents a proposed Change. As part of the Changes
process, proposals are publicly announced in order to receive
community feedback. This proposal will only be implemented if approved
by the Fedora Engineering Steering Committee.


== Summary ==

This change is to promote Fedora CoreOS to Edition status alongside
Workstation, Server and IoT.


== Owners ==

* Name: [[User:cverna|Clement Verna]]
* Email: cve...@fedoraproject.org

* Products: Fedora CoreOS
* Responsible WGs: Fedora CoreOS Group


== Detailed Description ==

This change is to promote Fedora CoreOS to Edition status alongside
Workstation, Server and IoT.

[https://fedoraproject.org/wiki/Editions/Promotion_Process#Prerequisites
Prerequisites] are tracked bellow :

* Edition has a team with regular public meeting :
[https://apps.fedoraproject.org/calendar/meeting/9437/ weekly meeting
happening on #fedora-meeting-1]

* Trademark approval from the Fedora Council :
[https://pagure.io/Fedora-Council/tickets/issue/340 council ticket]

* Product requirements document (PRD) :
https://fedoraproject.org/wiki/CoreOS/PRD

* Technical specification :
https://github.com/coreos/fedora-coreos-tracker/blob/master/Design.md


== Feedback ==

This change was previously submitted for Fedora 34 and feedback were
collected in the following [https://pagure.io/fesco/issue/2516 FESCo
ticket].
The 2 main feedback received are either addressed or in the process of
being addressed.

* FCOS should not trail behind the latest Major Fedora version: see
[[https://fedoraproject.org/wiki/Changes/FedoraCoreOS#Major_Fedora_Version_release_Go/NoGo|Major
Fedora Version release Go/NoGo criteria]]

* FCOS should demonstrate the test case mapping to the Basic Release
Criteria: see 
[[https://fedoraproject.org/wiki/Changes/FedoraCoreOS#Basic_Release_Criteria|Basic
Release Criteria]]


== Benefit to Fedora ==

Make Fedora CoreOS an official edition, will help spread adoption and
position Fedora as credible solution for running container workflow.

We have started to publish monthly update of what is happening in
Fedora CoreOS based on the feedback received from
[https://discussion.fedoraproject.org/t/fedora-coreos-survey/34408/2 a
community survey]. Part of these monthly update are
[https://discussion.fedoraproject.org/t/this-month-in-fedora-coreos-may-2022/39942#fcos-count-me-stats-3
the count me stats] which gives us a good understanding of FCOS
adoption.


== Scope ==
* Proposal owners: see change owners

* Other developers: N/A

* Release engineering: Fedora CoreOS is already being composed and released.

* Policies and guidelines: N/A

* Trademark approval: https://pagure.io/Fedora-Council/tickets/issue/340


== How To Test ==

See QA test cases :
https://fedoraproject.org/wiki/Category:CoreOS_Test_Cases and Fedora
CoreOS own test suite Kola
https://github.com/coreos/coreos-assembler/blob/main/docs/kola.md#testing-with-kola

We also have regular tests days, for example
https://fedoramagazine.org/fedora-coreos-test-day/


=== Basic Release Criteria ===

We are currently evaluating our compliance to the Fedora Basic Release
Criteria https://github.com/coreos/fedora-coreos-tracker/issues/1239.
This is an effort that will be done during the Fedora 37 development cycle.


==== Supported Architecture and Platforms ====

Fedora CoreOS is currently built for the x86_64, aarch64 and s390x
architecture, These
[https://docs.fedoraproject.org/en-US/fedora-coreos/platforms/#_well_known_ids
platforms] are supported and can be configured directly using
Ignition.

The [https://github.com/coreos/mantle/tree/cl/kola kola] test suite is
run for each stream release on AWS, Azure, GCP and OpenStack.


==== Stream release Go/NoGo ====

Stream releases are scheduled fortnightly, a GitHub issue
([https://github.com/coreos/fedora-coreos-streams/issues/242 example])
is created for each stream release with the release process.
The release status can be tracked in each ticket. If each steps and
validation were successful the release is considered GO.

Issues are reported in the
[https://github.com/coreos/fedora-coreos-tracker issue tracker] and
discussed during the weekly
[https://github.com/coreos/fedora-coreos-tracker#meetings IRC
meeting]. A stream release can become a NOGO during these meeting, the
blocker issue is then linked to the release GitHub issue.


==== Major Fedora Version release Go/NoGo ====

The policies around the Major version rebases are described in Fedora
CoreOS document
https://github.com/coreos/fedora-coreos-tracker/blob/main/Design.md#major-fedora-version-rebases
(see copy below)

The release process integrates with Fedora's release milestones in the
following ways:

Fedora Beta Release
  The next stream is switched over to the new release.
Fedora Final Freeze
  The next stream switches to weekly releases to closely track the GA
content set.
Fedora General Availability
Fedora CoreOS re-orients its release schedule in the following way:
  Week -1 (Fedora "Go" Decision): next release:
     next release with final Fedora GA content
  Week 0 (GA release): triple release:
     testing release promoted from previous next
     next release contains latest Fedora N content, including Bodhi updates
  Week 2: triple release:
     stable release promoted from previous testing, now fully rebased
to Fedora N
     testing and next are now in sync


== Contingency Plan ==
Contingency mechanism: (What to do? Who will do it?) Delay promotion until F38

Contingency deadline: F37 Final release date

Blocks release? No


== Documentation ==
https://docs.fedoraproject.org/en-US/fedora-coreos/
