# Enrolling a recipe under cc-ci (D5)

Adding a recipe is a small, repeatable, **no-harness-surgery** operation:

## 1. Make the recipe available on the mirror

Recipes under test live on the private mirror `git.autonomic.zone/recipe-maintainers/<recipe>`,
synced from upstream `git.coopcloud.tech`. If not yet mirrored, mirror it (abra fetch + push to the
org) — see the recipe mirror+PR flow (plan §4.1). A recipe may ship its own `tests/` dir in its repo;
those are discovered and run against the live app (D4 — see below).

## 2. Add the per-recipe test tree in this repo

```
tests/<recipe>/
├── recipe_meta.py      # optional per-recipe harness config (see below)
├── install_steps.sh    # optional custom install-steps hook (pre-deploy setup)
├── test_install.py     # optional install overlay  (else the generic install tier runs)
├── test_upgrade.py     # optional upgrade overlay   (else the generic upgrade tier runs)
├── test_backup.py      # optional backup overlay    (else the generic backup tier runs)
└── test_restore.py     # optional restore overlay   (else the generic restore tier runs)
```

**A recipe is testable with ZERO config:** with no overlay files, the **generic lifecycle suite**
runs (install/upgrade/backup/restore) against a single shared deployment — see `docs/testing.md` for
the full model (tiers, deploy-once, override-vs-extend, precedence, the install-steps hook). The
per-recipe dir only holds the bits where the recipe needs *more* than the generic.

To add recipe-specific coverage, drop a `tests/<recipe>/test_<op>.py` **overlay** (it OVERRIDES the
generic for that op; absent ⇒ generic runs). Overlays are **assertion-only** against the shared live
deployment (the `live_app` fixture; they never deploy), and reuse the generic op + serving check by
composition (`from harness import generic; generic.do_upgrade(...)` etc.), adding recipe-specific
assertions. Copy an existing overlay (`tests/custom-html/` simple/volume marker; `tests/keycloak/`
admin-API; `tests/matrix-synapse/` `db`-service psql marker). **Do not edit the shared
`tests/conftest.py` / `runner/harness/` to add a recipe** — set per-recipe config in `recipe_meta.py`:

```python
HEALTH_PATH = "/realms/master"   # path that returns a healthy status (default "/")
HEALTH_OK = (200,)               # acceptable status codes (default 200/301/302)
DEPLOY_TIMEOUT = 600             # seconds for services to converge (default 600)
HTTP_TIMEOUT = 600               # seconds for the app to answer (default 300)
BACKUP_CAPABLE = True            # override backup-capability auto-detect (default: scan compose)
EXTRA_ENV = {"KEY": "value"}     # or EXTRA_ENV(domain) -> dict; extra .env keys set at deploy
```

Useful `harness.lifecycle` helpers for overlays: `http_get`, `http_fetch`, `http_body`,
`exec_in_app` (use this for data markers — volume/DB, robust to the serving layer); the lifecycle ops
themselves come from `harness.generic` (`assert_serving`, `do_upgrade`, `do_backup`, `do_restore`).
The harness forces `LETS_ENCRYPT_ENV=""` (no ACME), a unique short domain per run, and guarantees
teardown.

## 3. Recipe-local tests (D4)

If the recipe's own repo contains `tests/test_*.py`, the runner snapshots them right after fetch and
runs them against the **live deployment** as a `recipe-local` stage. Contract: those tests receive
env `CCCI_BASE_URL` (e.g. `https://<app>.ci.commoninternet.net/`) and `CCCI_APP_DOMAIN`.

## 4. Add the repo to the bridge poll list

The trigger is **polling** (primary): add the repo's full name to the comment-bridge `POLL_REPOS`
csv (`nix/modules/bridge.nix`) and `nixos-rebuild switch`. The bridge then polls that repo's open PRs
every 30s and fires a run on a new `!testme` comment from an authorized org member. This needs only
**read + comment** access — no webhook, no repo-admin.

`!testme` on a PR runs install/upgrade/backup + any recipe-local tests, and reports back to the PR.

### Optional: lower-latency webhook (admin-registered)

Polling already satisfies D1 (<60s). For lower latency an **admin** may *optionally* register a
Gitea `issue_comment` webhook (the bot does **not** self-register one — that needs repo-admin):

- URL `https://ci.commoninternet.net/hook`, content-type `application/json`, event `Issue Comment`,
  secret = the shared webhook HMAC (`secrets/secrets.yaml` → `webhook_hmac`).
- The Gitea instance must allow the host (admin: add `ci.commoninternet.net` to the
  `[webhook] ALLOWED_HOST_LIST`).

The webhook and poller are deduped by comment id, so a comment seen by both fires only once.
