# Cutting a release

A release is one version across EduIDE-Cloud, EduIDE, EduIDE-Landing-Page and
EduIDE-Helm.
**Each repository releases on its own cadence.** EduIDE cuts `v1.3.0`, EduIDE-Cloud
cuts its own, the landing page cuts its own. A chart release then says which of
those versions belong together, and a deployment PR says which environments get
them.

**Do not bump the chart version from a workflow or by pushing to `main`.** The
release train deliberately does not do this, and neither should you. It checks
the charts are already at the requested version and fails otherwise. The bump is
a reviewed pull request; automation that pushes to `main` triggers the workflows
watching `main`.
So "release EduIDE 1.3.0 to production" is three merges in three repositories,
in this order. None of them is optional and the order is not a preference.

## 1. Dry run first, always
```
EduIDE release v1.3.0 images published as 1.3.0
EduIDE-Helm chart 2.3.0 appVersion 1.3.0 -> every IDE image
EduIDE-deployment chartVersion 2.3.0 merging this IS the deploy
```

## What a chart version pins

One knob per source repository, and the chart version is the name for the set:

| Value | Repository | Renders as |
|---|---|---|
| `appVersion` in `Chart.yaml` | EduIDE | every IDE image tag |
| `versions.cloud` in `values.yaml` | EduIDE-Cloud | operator, service, conversion webhook |
| `versions.landingPage` in `values.yaml` | EduIDE-Landing-Page | the landing page |

`versions.ide` in an environment's values overrides `appVersion` for that
installation. It exists for pinning an unreleased image - a `pr-123` tag - and
every use of it is temporary. If one is in place, the comment beside it should
say what has to become true before it goes, and that condition should be checked
whenever a release moves past it.

## 1. The component release exists first

Whatever you are pinning must already be published. Check, do not assume:

```bash
gh workflow run release-train.yml --repo EduIDE/EduIDE-Helm \
-f version=2.3.0 -f dry_run=true
gh release view v1.3.0 --repo EduIDE/EduIDE
gh run list --repo EduIDE/EduIDE --event release --limit 1 # did the build finish?
docker manifest inspect ghcr.io/eduide/eduide/java-17:1.3.0 # did it publish?
```

Read the summary. It reports which images the version would need, and builds
nothing.
A GitHub release existing means somebody clicked release. It does **not** mean
the images exist: the build runs after the tag, takes the better part of an
hour, and can fail. `release.yml` now refuses to publish a chart whose pinned
images are missing, so getting this wrong costs a red build rather than an
`ImagePullBackOff` in production - but it is still the first thing to check.

## 2. Bump both charts in a pull request
## 2. Bump the chart in a pull request

Both charts, both fields — four values, all identical:
Both charts carry the same version - CI enforces it - and only `appVersion`
moves with the component:

```yaml
# charts/eduide/Chart.yaml AND charts/eduide-cluster/Chart.yaml
version: 2.3.0
appVersion: "2.3.0"
# charts/eduide/Chart.yaml
version: 2.3.0 # and the same in charts/eduide-cluster/Chart.yaml
appVersion: "1.3.0" # the EduIDE release being pinned
```

Then regenerate the READMEs, or the `docs-drift` job fails:
Chart version is semver about **the chart**: a values change that alters
rendered output is a minor, a fix is a patch. It does not track the component
version and never has.

Then regenerate the READMEs, or `docs-drift` fails - the version badges come
from `Chart.yaml`:

```bash
docker run --rm -v "$PWD/charts:/helm-docs" -u "$(id -u)" jnorwood/helm-docs:v1.14.2
```

Open the PR and let CI run. Do not merge it yourself unless asked to.
Open the PR, let CI run, and do not merge it yourself unless asked.

## 3. Run it for real
## 3. Merging publishes and releases it

```bash
gh workflow run release-train.yml --repo EduIDE/EduIDE-Helm \
-f version=2.3.0 -f dry_run=false
```
`release.yml` runs on push to `main` and does four things in order:

1. verifies every image the chart pins exists and is multi-arch
2. packages and pushes any chart whose version is not already published
3. tags the repository `vX.Y.Z`
4. creates a GitHub release naming what the version pins, with generated notes

Step 1 reads the IDE image list from EduIDE's build matrix at run time rather
than from a list here, because a hand-kept copy drifts the moment somebody adds
an image and then a release verifies a subset and passes.

If `main` carries no version bump, steps 2 to 4 do nothing. That is every
ordinary merge.

Order: validate, build all 14 images, verify they exist and are multi-arch,
**then** tag, then publish. Building before tagging means a flaky image build
costs a re-run rather than stranding immutable tags on repositories whose
images were never published.
## 4. Roll it out

## 4. Roll it out separately
Nothing here deploys. In EduIDE-deployment, bump `spec.platform.chartVersion` in
the relevant `environments/*/env.yaml`, in a pull request - staging first, then
production, in separate PRs so production can be reverted without reverting the
environment that proved it. Merging the production one is the deploy.

The train deploys nothing. In EduIDE-deployment, bump
`spec.platform.chartVersion` in the relevant `environments/*/env.yaml`, in a
pull request. Production is never deployed automatically.
## The release train is a different thing

## Version forms
`release-train.yml` moves **all four repositories to one number** and requires
both charts to carry that number in both `version` and `appVersion`. That is a
deliberate lockstep release, not this process, and running it against an
ordinary `main` fails its pre-check by design.

- git tags `vX.Y.Z`
- chart `version`, chart `appVersion` and image tags all `X.Y.Z`
- release candidates `2.3.0-rc.1` throughout
Reach for it only when you actually want every component rebuilt and retagged
together. Almost nothing needs that.

## Common failures

| Message | Meaning |
|---|---|
| `version is 'X', expected 'Y'` | step 2 skipped, or only one chart/field bumped |
| `missing ghcr.io/...` | a component build failed; check that repository's Actions |
| `is not multi-arch` | one architecture failed; re-run the whole build, not just the merge job |
| `tag v2.3.0 already exists` | pick the next version, tags are immutable |
| `missing ghcr.io/...` in Release Charts | step 1 - the component release's build has not finished, or failed |
| `is not multi-arch` | one architecture failed in the component build; re-run that build, not this one |
| `eduide is X but eduide-cluster is Y` | the two charts drifted; they release together at one version |
| `changed but version is still X` | a chart changed with no bump; `release.yml` would publish nothing |
| `chart READMEs are out of date` | run helm-docs and commit the result |
| `tag vX.Y.Z already exists` | the charts were published under that version already; bump |
| Chart published but no release | the tag already existed - the charts are out, only the release page is missing |

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)
