What and why

Adds this repo to the org-wide Renovate rollout (shared preset: EduIDE/.github#4), and fixes the gap that made the existing validation job weaker than it looks.

The repo is not the shape the shared preset expects

The preset carries a custom manager aimed at deployments/*/values.yaml and the preloading.images lists in it, plus a deployments/** package rule. Neither matches anything here any more. deployments/ and charts/ were deleted in #111 and #113; preload images are derived from appDefinitions.apps in the chart, and AGENTS.md now says in as many words "do not list images to preload". There are no chart sources in this repo either - both charts live in EduIDE-Helm and are pulled from oci://ghcr.io/eduide/charts.

They are inert rather than wrong, so nothing here breaks. Worth cleaning up in EduIDE/.github separately; I have not touched that PR.

What is actually versioned here, and what manages it

Two things:

Managed by
Actions in .github/workflows/* the preset's github-actions manager, already
spec.platform.chartVersion in environments/<name>/env.yaml a custom regex manager added here

The second needs a custom manager because env.yaml is an eduide.dev/v1 Environment manifest - not a Chart.yaml, not a Helm values file - so neither helmv3 nor helm-values can see it. Without it this repo's Renovate config would be decorative.

eduide-cluster is passed to Bootstrap cluster as a workflow input rather than written in a file, so nothing can bump it. Documented in AGENTS.md as a by-hand step.

The production / staging split

This is the decision worth arguing about, so, explicitly:

  • Production (tum-production, bonn, mannheim) sits behind dependencyDashboardApproval: true in its own group. Per the README, bumping chartVersion in environments/tum-production/env.yaml and opening a PR is the production release procedure. A Renovate PR against that file is therefore not a dependency update that happens to touch production - it is a production deploy sitting there waiting for someone to hit merge. It must not appear unasked.
  • Staging and test (staging, e2e-test, test1, test2, test3) batch into a single PR on the normal Monday schedule.

They are kept in separate groups rather than one, because a single PR moving all eight would mean production could not be reverted without also reverting the environments it is supposed to have been proven on first - and vice versa.

Grouping is by path, not by tier, because Renovate cannot read metadata.tier out of the manifest. If a fourth production environment is added, its path needs adding to the first rule. That is a real maintenance edge and I would rather state it than hide it.

Helm in the validation job

Validate environments already runs scripts/test-deploy-logic.sh on every PR, and that script renders all eight environments against the published chart. But helm was never installed on the runner, so that whole section printed SKIP chart ... not reachable and the job went green having rendered nothing. The README's claim that CI "renders every environment" was not true.

Rather than add a second workflow that renders the same things again, this installs azure/setup-helm@v4 at v3.16.3 - the version the deploy workflows already pin - and adds one step that fails if the chart cannot be pulled, so the skip cannot silently come back. The script keeps skipping on a laptop with no helm, which is why it was written that way.

helm lint / helm template over charts/ was not possible: there is no charts/ directory in this repo.

Also moves the pinned yq version into a YQ_VERSION env var with a # renovate: annotation, so the preset's customManagers:githubActionsVersions picks it up. It was the one other pinned version in the repo.

How it was verified

Run locally against this branch:

  • renovate-config-validator --strict renovate.json (renovate 44.46.7) - passes. Confirmed it is doing real work by feeding it a deliberately bogus option in a scratch copy and watching it fail.
  • Custom manager regex, against the real files: 8 matches, exactly one per environment manifest, all 2.0.0. values.yaml and _base.yaml are correctly not matched by managerFilePatterns. A manager that matches nothing fails silently, so this was checked rather than assumed.
  • matchFileNames globs, through minimatch: chart-prod -> 3 files (bonn, mannheim, tum-production), chart-test -> 5 files (e2e-test, staging, test1, test2, test3), zero manifests uncovered by either.
  • scripts/test-deploy-logic.sh - ALL PASS, on helm v3.16.3 specifically (the CI version), not just on whatever was already installed. All eight environments render against oci://ghcr.io/eduide/charts/eduide:2.0.0. Anonymous pull from ghcr works, so the runner needs no credentials.
  • scripts/check-agents-md.sh - passes.
  • actionlint - clean. Note: the v1.7.7 download script installed 1.7.6, so that is the version that actually ran.
  • The reworked yq download URL resolves (HTTP 200 on the ${YQ_VERSION} form).

Not verified: real grouping and scheduling behaviour. That needs renovate --dry-run=full, which cannot resolve local>EduIDE/.github:renovate-config until EduIDE/.github#4 is on main. Until then this config fails closed - a missing preset means no PRs, not wrong PRs.

Deployment impact

  • Requires a config change in EduIDE-deployment

This is that config change, and it is a change to how deployment config gets updated rather than to any deployed value. Nothing rendered changes: chartVersion stays at 2.0.0 in all eight environments and no values file is touched.

The one thing to be aware of: once the Renovate app is installed on the org, the chart-test group will open PRs that bump the chart version for staging and all three test environments. Merging one is a real deploy of those environments on the next run. Production will not move without a Dependency Dashboard tick.

  • Changes a Helm chart (chart version bumped)
  • Changes a published image
  • Requires a cluster-level change (CRDs, Gateway, ClusterRoles)

Risk and rollback

Low, and mostly deferred. The Renovate app is not installed on the org yet, so renovate.json is inert until it is - deliberately the last step of the rollout.

The live risk is the workflow change, and it is the honest kind: CI does more now than it did yesterday, so it can newly go red. Specifically it will fail if ghcr is unreachable or the pinned chart version is gone. That is the point - the alternative is what we had, where the render coverage evaporated and nothing said so. If it turns out to be flaky in practice, the fix is dropping the reachability step and accepting the skip, not reverting the helm install.

A bad rule in renovate.json shows up as noisy or missing PRs, never as something merged: automerge: false everywhere in the preset, and this repo has no automerge of its own.

Rollback: revert the commit. Renovate stops raising PRs, the validation job goes back to skipping its renders.

Summary by CodeRabbit

  • New Features

    • Added automated dependency update configuration for environment chart versions and workflow actions.
    • Added validation to confirm referenced Helm charts are reachable and renderable before checks proceed.
    • Added Helm installation and pinned yq tooling for more consistent validation runs.
  • Documentation

    • Documented dependency update behavior, approval requirements, and repository layout.

Adds this repo to the org-wide Renovate rollout, and closes the gap that
made the existing validation job weaker than it looks.

The repo no longer matches the shape the shared preset was written for.
`deployments/*/values.yaml` and the `preloading.images` lists it targets
with a custom manager were deleted in #111 and #113 - preload images are
derived from `appDefinitions.apps` in the chart now, and there are no
chart sources here at all since 2.0.0. That manager, and the preset's
`deployments/**` package rule, match nothing in this repo. Both are inert
rather than wrong; raising it against EduIDE/.github separately.

So the only versioned things left here are the actions in the workflows
and `spec.platform.chartVersion` in each environment manifest. The second
needs a custom manager: env.yaml is an eduide.dev/v1 Environment, so
neither helmv3 nor helm-values can read it. Verified the regex matches
exactly once per environment, 8 of 8, and does not touch values.yaml or
_base.yaml.

Production is separated from staging and test by path. Bumping
chartVersion in a production environment is not a chore that happens to
touch production - it is the documented release procedure, so it waits
behind a Dependency Dashboard tick. Grouping it with the test
environments would produce one PR that cannot be reverted for production
without also reverting the environments it was meant to be proven on.
Verified the two rules partition all eight manifests with none left over.

Also installs helm in the validation job. test-deploy-logic.sh renders
every environment against the published chart, but helm was never on the
runner, so that section printed SKIP and the job went green having
rendered nothing - the README's claim that CI "renders every environment"
was not true. An unreachable chart is now a failure in CI and still a
skip on a laptop.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds Renovate configuration for environment chart versions, documents the update policy, pins the yq version, installs Helm in validation, and checks that the test environment’s referenced chart is reachable.

Changes

Dependency management and CI validation

Layer / File(s) Summary
Renovate chart update policy
renovate.json, AGENTS.md, README.md
Renovate detects spec.platform.chartVersion in environment manifests. Production updates require dashboard approval. Staging and test updates use a separate group. Repository documentation describes this policy.
CI Helm and chart validation
.github/workflows/validate.yml
The workflow installs Helm v3.16.3, manages yq through YQ_VERSION, and verifies that the chart version in environments/test1/env.yaml is reachable.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 341dd

The PR adds automated chart rendering and Renovate-managed updates, but the validation job may fail on registry access and may not verify each environment against its declared chart version. Merge should wait for these risks to be corrected or explicitly accepted; the documentation mismatch is minor.

Check every environment's chart version.

test-deploy-logic.sh also renders every environment with the version read from environments/test1/env.yaml. Separate Renovate groups can produce divergent versions, so an environment can be validated against the wrong chart version. Pull and render each unique environment version, or enforce a single-version invariant.
