stable: new release on 2023-12-04 (39.20231119.3.0)

[prestist]

First, verify that you meet all the prerequisites

Edit the issue title to include today's date. Once the pipeline spits out the new version ID, you can append it to the title e.g. (31.20191117.3.0).

Pre-release

Promote testing changes to stable

• Add the ok-to-promote label to the issue
• Review the promotion PR against the stable branch on https://github.com/coreos/fedora-coreos-config
• Once CI has passed, merge it

Manual alternative

Sometimes you need to run the process manually like if you need to add an extra commit to change something in manifest.yaml. The steps for this are:

• git fetch upstream
• git checkout stable
• git reset --hard upstream/stable
• /path/to/fedora-coreos-releng-automation/scripts/promote-config.sh testing
• Open PR against the stable branch on https://github.com/coreos/fedora-coreos-config

Build

• Start a build job (select stable, leave all other defaults). This will automatically run multi-arch builds.
• Post links to the jobs as a comment to this issue
  • x86_64
  • aarch64 (multi-arch build job)
  • ppc64le (multi-arch build job)
  • s390x (multi-arch build job)
• Wait for the jobs to finish and succeed
  • x86_64
  • aarch64
  • ppc64le
  • s390x

Sanity-check the build

Using the the build browser for the stable stream:

• Verify that the parent commit and version match the previous stable release (in the future, we'll want to integrate this check in the release job)
  • x86_64
  • aarch64
  • ppc64le
  • s390x
• Check kola extended upgrade runs to make sure they didn't fail
  • x86_64
  • aarch64
  • ppc64le
  • s390x
• Check kola AWS runs to make sure they didn't fail
  • x86_64
  • aarch64
• Check kola OpenStack runs to make sure they didn't fail
  • x86_64
  • aarch64
• Check kola Azure run to make sure it didn't fail
  • x86_64
• Check kola GCP runs to make sure they didn't fail
  • x86_64
  • aarch64

⚠️ Release ⚠️

IMPORTANT: this is the point of no return here. Once the OSTree commit is
imported into the unified repo, any machine that manually runs rpm-ostree upgrade will have the new update.

Run the release job

• Run the release job, filling in for parameters stable and the new version ID
• Post a link to the job as a comment to this issue
• Wait for job to finish

At this point, Cincinnati will see the new release on its next refresh and create a corresponding node in the graph without edges pointing to it yet.

Refresh metadata (stream and updates)

• Wait for all releases that will be released simultaneously to reach this step in the process
• Go to the rollout workflow, click "Run workflow", and fill out the form

Rollout general guidelines

Risk	Day of the week	Rollout Start Time	Time allocation
risky	Tuesday	2PM UTC	72H
common	Tuesday	2PM UTC	48H
rapid	Tuesday	2PM UTC	24H

When setting a rollout start time ask "when would be the best time to react to
any errors or regressions from updates?". Commonly we select 2PM UTC so that the
rollout's start at 10am EST(±1 for daylight savings), but these can be fluid and
adjust after talking with the fedora-coreos IRC. Note, this is impacted by the
day of the week and holidays.

The later in the week the release gets held up due to unforeseen issues the more
likely the rollout time allocation will need to shrink or the release will need
to be deferred.

Manual alternative

• Make sure your fedora-coreos-stream-generator binary is up-to-date.

From a checkout of this repo:

• Update stream metadata, by running:

fedora-coreos-stream-generator -releases=https://fcos-builds.s3.amazonaws.com/prod/streams/stable/releases.json  -output-file=streams/stable.json -pretty-print

• Add a rollout. For example, for a 48-hour rollout starting at 10 AM ET the same day, run:

./rollout.py add stable <version> "10 am ET today" 48

• Commit the changes and open a PR against the repo

• Verify that the expected OS versions appear in the PR on https://github.com/coreos/fedora-coreos-streams
• Post a link to the resulting PR as a comment to this issue
• Review and approve the PR, then wait for someone else to approve it also
• Once approved, merge it and verify that the sync-stream-metadata job syncs the contents to S3
• Verify the new version shows up on the download page
• Verify the incoming edges are showing up in the update graph.
  • x86_64
  • aarch64
  • ppc64le
  • s390x

Update graph manual check

curl -H 'Accept: application/json' 'https://updates.coreos.fedoraproject.org/v1/graph?basearch=x86_64&stream=stable&rollout_wariness=0'
curl -H 'Accept: application/json' 'https://updates.coreos.fedoraproject.org/v1/graph?basearch=aarch64&stream=stable&rollout_wariness=0'
curl -H 'Accept: application/json' 'https://updates.coreos.fedoraproject.org/v1/graph?basearch=ppc64le&stream=stable&rollout_wariness=0'
curl -H 'Accept: application/json' 'https://updates.coreos.fedoraproject.org/v1/graph?basearch=s390x&stream=stable&rollout_wariness=0'

NOTE: In the future, most of these steps will be automated.

Housekeeping

• If one doesn't already exist, open an issue in this repo for the next release in this stream. Use the approximate date of the release in the title.
• Issues opened via the previous link will automatically create a linked Jira card. Assign the GitHub issue and Jira card to the next person in the rotation.

@prestist (cc. @yasminvalim) do you mind if I take over the release process next week?

[prestist]

@c4rt0 Yes that would be amazing

Currently build-arch is facing issue which should be solved by #PR 3679.

[dustymabe]

• aarch64 Build
• ppc64le Build
• s390x Build

[c4rt0]

Re-run:

• aarch64 Build

[dustymabe]

Ahh https://jenkins-fedora-coreos-pipeline.apps.ocp.fedoraproject.org/blue/organizations/jenkins/build-arch/detail/build-arch/3130/pipeline failed because of coreos/coreos-assembler#3669

coreos/fedora-coreos-config#2745 isn't backported to the stable branch.

[dustymabe]

Since all the tests except the coreos.unique.boot.failure passed and that one is a known failure for a newly added test I started a new run to just skip the kola tests at that spot:

• aarch64 Build
