Re-lands #45. That PR was stacked on chore/chart-2.3.0-eduide-1.3.0 and merged into that branch rather than into main, so its changes never reached main - GitHub only retargets a stacked PR when its base branch is deleted, and #43 was merged without deleting it. Same four files, unchanged, on current main.

Also worth knowing before merging: chart 2.3.0 has no GitHub release and no v2.3.0 tag, because it was published by #43's merge before this code existed. release.yml skips chart versions that are already published, so merging this will not backfill it - the first release page will appear on the next version bump. See "Backfill" below.

Three gaps this closes

The release published without checking the images exist. A chart version is a promise about images: appVersion pins every IDE image, versions.cloud the operator and service, versions.landingPage the landing page. Nothing verified it, so a chart could go out naming tags nobody pushed, surfacing as ImagePullBackOff in whichever environment installed it next. release.yml now verifies every pinned image exists and is multi-arch before pushing, reading the IDE image list from EduIDE's build matrix at run time rather than from a copy kept here.

Not hypothetical: EduIDE v1.3.0's image build was still running when the chart bump was opened, and the only thing between that and a broken production deploy was remembering to look.

Nothing recorded what is current. The release train pushed a bare git tag for this repository and created proper GitHub releases only in the component repos. There is now a release per published chart version:

Charts published to `oci://ghcr.io/eduide/charts`:

- `eduide-cluster` 2.3.0
- `eduide` 2.3.0

## What this chart version pins

| Component | Version |
|---|---|
| IDE images (EduIDE) | 1.3.0 |
| Operator and service (EduIDE-Cloud) | 1.2.0 |
| Landing page | 1.2.2 |
...

followed by --generate-notes' commit list.

Nothing enforced one version across both charts. AGENTS.md says they are released together at the same version; they had drifted to 2.2.1 and 2.2.2. CI now checks it.

The release train

Left working, with its header and failure message rewritten to say what it is: a lockstep release moving all four repositories to one number, not the ordinary path. Running it against a normal main fails its pre-check by design, which previously read like a bug. This settles #44 in favour of per-repo versions.

The skill

.claude/skills/cut-a-release.md described the lockstep model as the only model. Rewritten around the real process - component release, chart release, deployment PR - with the ordering, the versions.ide override and when it must be removed, and a failure table.

Backfill

Once this merges, v2.3.0 can be created once by hand so the current version is visible:

gh release create v2.3.0 --repo EduIDE/EduIDE-Helm --title v2.3.0 --generate-notes \
  --notes "Charts eduide and eduide-cluster 2.3.0. Pins IDE images 1.3.0, cloud 1.2.0, landing page 1.2.2."

Happy to do that on request rather than as part of this.

Verification

actionlint clean on all three workflows; scripts/test-app-consistency.sh ALL PASS. The publish and release steps only run on push to main, so CI here exercises everything except the release path itself - the first merge carrying a version bump is where to watch it.

Summary by CodeRabbit

  • New Features
    • Chart releases now verify that pinned IDE, cloud, and landing-page images are available for both amd64 and arm64 before publishing.
    • When charts are published, the workflow creates a version tag and GitHub release with chart and image details; versions containing - are marked as prereleases. Existing tags are not released again.
  • Bug Fixes
    • CI now fails when the two chart versions do not match.
  • Documentation
    • Release guidance distinguishes independent chart releases, deployments, and lockstep release trains, including their version requirements.

Re-lands #45, which was merged into its stacked base branch rather than
main and so never reached it. Same four files, unchanged, on current main.

Three gaps in the chart release:

It published without checking the images the chart names exist. A chart
version is a promise about images - appVersion pins every IDE image,
versions.cloud the operator and service - and breaking it surfaces as an
ImagePullBackOff in whichever environment installs it next. The IDE image
list is read from EduIDE's build matrix at run time, because a copy kept
here drifts the moment someone adds an image.

It left no record of what is current. The repository got a bare tag from
the release train and nothing else. There is now a GitHub release naming
the chart version, what it pins, and how to roll it out, ahead of the
generated commit notes.

Nothing checked that the two charts carry the same version, which AGENTS.md
says they do; they had drifted to 2.2.1 and 2.2.2.

📝 Walkthrough

Walkthrough

The changes document independent component and chart releases, add image validation and chart release creation to the release workflow, and check chart-version parity in CI. They also clarify the separate deployment rollout and four-repository lockstep release process.

Changes

Chart release process

Layer / File(s) Summary
Chart versions and release model
.claude/skills/cut-a-release.md, .github/workflows/ci.yml
The skill describes independently paced component and chart versions, chart version rules, and temporary IDE version overrides. CI checks that the two chart versions match.
Image validation and chart publication
.claude/skills/cut-a-release.md, .github/workflows/release.yml
The release workflow checks pinned image manifests and architectures, publishes eligible charts, and creates a tag and GitHub release. The skill documents the checks, publication conditions, and failure outcomes.
Deployment and lockstep release paths
.claude/skills/cut-a-release.md, .github/workflows/release-train.yml
The skill describes environment rollout as a separate deployment change and documents the four-repository lockstep process. The release-train workflow comments and mismatch error distinguish it from ordinary chart releases.

Review details

Before / after behavior

  • observed — Modified behavior in .claude/skills/cut-a-release.md: The skill description now defines this as releasing an EduIDE chart to move a component version into environments, and lists chart publishing and environment rollout requests as triggers; it no longer describes a four-repository platform release.
  • observed — Modified behavior in .claude/skills/cut-a-release.md: The overview replaces the single shared-version model with independently paced repository releases, a chart version that groups component versions, and a deployment PR that selects the environments. It states that a production release requires three ordered merges: release EduIDE, release the Helm chart, then update EduIDE-deployment.
  • observed — Modified behavior in .claude/skills/cut-a-release.md: The chart-version section maps appVersion to EduIDE images, versions.cloud to EduIDE-Cloud images, and versions.landingPage to the landing page. It also documents that an environment’s versions.ide overrides appVersion for a temporary unreleased-image pin, with a comment specifying and checking its removal condition.
  • observed — Modified behavior in .claude/skills/cut-a-release.md: The first step now requires checking that the component release and images exist, using release, workflow, and image-manifest checks. It distinguishes a GitHub release from completed image publication and states that release.yml rejects a chart with missing pinned images.

Read the image matrix for the pinned EduIDE version.

This request omits ref, so GitHub returns the current default-branch workflow. A later EduIDE release can add an image that was not built for the chart’s pinned appVersion. A subsequent chart-only release then fails the manifest check even though its pinned images exist. Read the matrix at the EduIDE tag corresponding to ide, or validate the image set recorded for that release. (docs.github.com)

Allow a rerun to complete an interrupted GitHub release.

If the job fails after helm push but before gh release create, a rerun skips the already-published charts. steps.publish.outputs.charts is then empty, so the release step never runs. If the tag was pushed before the failure, Line 160 also exits without creating the missing release. Decide whether to create the release by checking chart and release state, rather than only whether this run pushed charts; reuse an existing tag when it has no release. GitHub CLI supports creating a release from a previously pushed annotated tag. (cli.github.com)
