elastic#262224) ## Summary Implements a fully automated Buildkite pipeline for Kibana version bumps, supporting both **patch** and **minor** release workflows. The steps are based on the [release document](https://docs.elastic.dev/kibana-team/release) and talks with @mistic. ## What this does ### Pipeline orchestration (`pipeline.ts`) A dynamic pipeline generator that emits different step sequences depending on the `WORKFLOW` env var: **Patch workflow:** 1. Trigger ES build and promote 2. Bump `package.json` versions + `versions.json` on the release branch 3. Trigger DRA snapshot (+ staging if not `main`) 4. Update version label color + reconcile PR labels **Minor workflow:** 1. Trigger ES build and promote 2. Bump `package.json` versions + `versions.json` on `main` 3. Trigger DRA snapshot (+ staging if not `main`) 4. Do changes in the new branch 5. Notify `#mission-control` that Kibana has been branched (version bump still pending) 6. Update release branch config + pipeline resource definitions 8. Create new release branch off `main` 9. Ensure version label exists + reconcile PR labels ### New scripts | Script | Purpose | |--------|---------| | `bump.sh` | Entry point that generates and uploads the dynamic pipeline | | `bump_package_json_versions.sh` | Bumps `package.json` and other files on the release branches | | `bump_versions_json.sh` | Updates `versions.json` and `backportrc` for patch/minor/major releases | | `create_new_branch_of_main.sh` | Creates and pushes a new release branch from `main` | | `update_release_branch.sh` | Updates config files on the new release branch | | `update_pipeline_resource_definitions.sh` | Updates the Buildkite pipeline resource definitions in main | | `ensure_version_label.sh` | Creates the GitHub version label if it doesn't exist | | `update_label_color.sh` | Updates the version label color to mark it as current | | `reconcile_pr_labels.sh` | Reconciles version labels on open PRs | | `notify_branch_created.sh` | Sends a Slack notification to `#mission-control` when a branch is created | | `wait_for_pr_merge.sh` | Utility to poll until an auto-merge PR is merged | ### Pipeline resource definition Adds `kibana-version-bump` Buildkite pipeline resource definition with appropriate team access controls. ### Auto-approve workflow Adds the version bump pipeline to the list of workflows eligible for automatic approval of machine-generated PRs ### ES Build Added step to add ES_SNAPSHOT as metadata to triggered parents job.
