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: cverna@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_rel... 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%7... 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/... 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-wi...
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_id... 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-fe... (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/

Consider updating the proposal to include Cloud since it now has Edition status once again.

Updated!
Thanks for the feedback.
We also probably need a new FESCO ticket. The current one still points to the one from the F34 change request: - https://fedoraproject.org/wiki/Changes/FedoraCoreOS - https://pagure.io/fesco/issue/2516

Yes. I imagine as part of this process a new ticket will get created for F37

I don't feel this is sufficiently addressed. Why is it that the stable stream can't be switched when all the other artifacts are released? Why is it two weeks *after* GA?

Fedora CoreOS is unique in that by default nodes are automatically updated. We let the exact content set that we are going to ship to our `stable` stream bake in our `testing` stream for ~two weeks. This allows people to find issues that we don't find in our CI and report them. We find CI is good, but there is no substitute for real workloads.
The exact content set delivered as part of Fedora GA isn't available two weeks before GA date so it's hard for us to ship GA content in our `stable` stream on GA day and follow our current update model.
We do have the `next` stream which does get updated often in the weeks before GA, but a significantly smaller set of users are running `next`.

Given the amount of testing happening to produce GA, is it possible to have an exception to the 2 week rule for GA?

I did talk about this with Dusty already, and my opinion is the two week delay is fine. The situations aren't the same, as Dusty said, CoreOS is unique here: pushing something out on the 'stable' stream means that almost all CoreOS users (who haven't changed the default config) will get it almost immediately. That's not the case with 'regular' Fedora installs, where the user chooses when to upgrade. Many users don't upgrade to a new release as soon as it comes out, they'd rather wait and see how things shake out. For me, the two week delay for the CoreOS 'stable' stream to be kicked over is just the same as that.
I wouldn't be happy if we didn't have a coherent and definite story to tell here, but "the CoreOS stable stream will update to the new release in two weeks, or you can switch to the 'next' stream to get it right away!" is a perfectly fine story to tell on release day, I think.
