Documenting a feature for a release
Each major Kubernetes release introduces new features that require documentation. New releases also bring updates to existing features and documentation (such as upgrading a feature from alpha to beta).
Generally, the SIG responsible for a feature submits draft documentation of the
feature as a pull request to the appropriate development branch of the
kubernetes/website repository, and someone on the SIG Docs team provides
editorial feedback or edits the draft directly. This section covers the branching
conventions and process used during a release by both groups.
For documentation contributors
In general, documentation contributors don't write content from scratch for a release. Instead, they work with the SIG creating a new feature to refine the draft documentation and make it release ready.
After you've chosen a feature to document or assist, ask about it in the
Slack channel, in a weekly SIG Docs meeting, or directly on the PR filed by the
feature SIG. If you're given the go-ahead, you can edit into the PR using one of
the techniques described in
Commit into another person's PR.
Find out about upcoming features
To find out about upcoming features, attend the weekly SIG Release meeting (see the community page for upcoming meetings) and monitor the release-specific documentation in the kubernetes/sig-release repository. Each release has a sub-directory in the /sig-release/tree/master/releases/ directory. The sub-directory contains a release schedule, a draft of the release notes, and a document listing each person on the release team.
The release schedule contains links to all other documents, meetings, meeting minutes, and milestones relating to the release. It also contains information about the goals and timeline of the release, and any special processes in place for this release. Near the bottom of the document, several release-related terms are defined.
This document also contains a link to the Feature tracking sheet, which is the official way to find out about all new features scheduled to go into the release.
The release team document lists who is responsible for each release role. If it's not clear who to talk to about a specific feature or question you have, either attend the release meeting to ask your question, or contact the release lead so that they can redirect you.
The release notes draft is a good place to find out about specific features, changes, deprecations, and more about the release. The content is not finalized until late in the release cycle, so use caution.
Feature tracking sheet
The feature tracking sheet for a given Kubernetes release lists each feature that is planned for a release. Each line item includes the name of the feature, a link to the feature's main GitHub issue, its stability level (Alpha, Beta, or Stable), the SIG and individual responsible for implementing it, whether it needs docs, a draft release note for the feature, and whether it has been merged. Keep the following in mind:
- Beta and Stable features are generally a higher documentation priority than Alpha features.
- It's hard to test (and therefore to document) a feature that hasn't been merged, or is at least considered feature-complete in its PR.
- Determining whether a feature needs documentation is a manual process. Even if a feature is not marked as needing docs, you may need to document the feature.
For developers or other SIG members
This section is information for members of other Kubernetes SIGs documenting new features for a release.
If you are a member of a SIG developing a new feature for Kubernetes, you need
to work with SIG Docs to be sure your feature is documented in time for the
release. Check the
feature tracking spreadsheet
or check in the
#sig-release Kubernetes Slack channel to verify scheduling details and
Open a placeholder PR
- Open a draft pull request against the
dev-1.27branch in the
kubernetes/websiterepository, with a small commit that you will amend later. To create a draft pull request, use the Create Pull Request drop-down and select Create Draft Pull Request, then click Draft Pull Request.
- Edit the pull request description to include links to kubernetes/kubernetes PR(s) and kubernetes/enhancements issue(s).
- Leave a comment on the related kubernetes/enhancements issue with a link to the PR to notify the docs person managing this release that the feature docs are coming and should be tracked for the release.
If your feature does not need
any documentation changes, make sure the sig-release team knows this, by
mentioning it in the
#sig-release Slack channel. If the feature does need
documentation but the PR is not created, the feature may be removed from the
PR ready for review
When ready, populate your placeholder PR with feature documentation and change the state of the PR from draft to ready for review. To mark a pull request as ready for review, navigate to the merge box and click Ready for review.
Do your best to describe your feature and how to use it. If you need help structuring your documentation, ask in the
#sig-docs slack channel.
When you complete your content, the documentation person assigned to your feature reviews it. To ensure technical accuracy, the content may also require a technical review from corresponding SIG(s). Use their suggestions to get the content to a release ready state.
If your feature is an Alpha or Beta feature and is behind a feature gate, make sure you add it to Alpha/Beta Feature gates table as part of your pull request. With new feature gates, a description of the feature gate is also required. If your feature is GA'ed or deprecated, make sure to move it from that table to Feature gates for graduated or deprecated features table with Alpha and Beta history intact.
If your feature needs documentation and the first draft content is not received, the feature may be removed from the milestone.
All PRs reviewed and ready to merge
If your PR has not yet been merged into the
dev-1.27 branch by the release deadline, work with the
docs person managing the release to get it in by the deadline. If your feature needs
documentation and the docs are not ready, the feature may be removed from the
