# Deployment runbook

Single-host deployment of the RFC app at `rfc.wiggleverse.org`,
sharing infrastructure with `git.wiggleverse.org` (same Gitea
instance, same nginx, same Let's Encrypt). The shape matches §4.2:
one process, one SQLite file, no separate worker.

Bring-up order: host prep → Gitea side (bot, OAuth, meta repo) → app
side (code, venv, build, .env) → web server side (nginx, certbot) →
systemd → smoke-test.

Every step is idempotent or no-op-on-rerun, so re-running this
runbook to recover from a partial install is safe.

---

## Prereqs

- Ubuntu/Debian-style host with nginx and certbot already serving
  `git.wiggleverse.org` over HTTPS.
- DNS: an `A` record for `rfc.wiggleverse.org` pointing at the same
  IP as `git.wiggleverse.org`.
- Python 3.11+ available system-wide. Node 20+ available (for
  `npm run build` once; the build output is what runs in production —
  Node isn't needed at runtime).

---

## 1. Host prep

Create the system user and the install directory.

```sh
sudo useradd --system --shell /usr/sbin/nologin --home-dir /opt/rfc-app rfc-app
sudo mkdir -p /opt/rfc-app
sudo chown rfc-app:rfc-app /opt/rfc-app
```

Clone the repo. Use HTTPS since we don't need to push from the server.

```sh
sudo -u rfc-app git clone https://git.wiggleverse.org/ben.stull/rfc-app.git /opt/rfc-app
```

---

## 2. Gitea side

### 2.1 Create the bot service account

In the Gitea web UI, signed in as a Gitea admin:

- **Site Administration → User Accounts → Create User Account**
- Username: `rfc-bot` (or whatever you want)
- Email: anything sensible (e.g. `rfc-bot@wiggleverse.org`)
- Password: random, you won't use it interactively
- Send email confirmation: off

Then sign in as the bot, open **Settings → Applications → Generate
New Token**, name it `rfc-app`, grant scopes:

- `write:repository`
- `write:user`
- `write:admin` (needed because the bot creates per-RFC repos on
  graduation — scope down to `repo`+`org` if you want to defer admin
  until Slice 5)

Copy the token. It goes into `.env` as `GITEA_BOT_TOKEN`.

### 2.2 Create the org and add the bot

The meta repo lives inside an org. In Gitea: **Create Organization →
wiggleverse**. Then **Members → Invite → rfc-bot → Owner**.

### 2.3 Register the OAuth2 application

**Site Administration → Integrations → OAuth2 Applications →
Create Application**:

- Name: `RFC App`
- Redirect URI: `https://rfc.wiggleverse.org/auth/callback`

Copy the client ID and client secret. They go into `.env`.

---

## 3. App side

### 3.1 Python venv + deps

```sh
sudo -u rfc-app python3 -m venv /opt/rfc-app/backend/.venv
sudo -u rfc-app /opt/rfc-app/backend/.venv/bin/pip install \
    -r /opt/rfc-app/backend/requirements.txt
```

### 3.2 Build the frontend

Build locally if you don't want Node on the server; copy `dist/`
across:

```sh
# On your laptop:
cd frontend && npm install && npm run build
rsync -a dist/ ben.stull@<host>:/tmp/rfc-app-dist/
# On the host:
sudo -u rfc-app mkdir -p /opt/rfc-app/frontend/dist
sudo cp -r /tmp/rfc-app-dist/. /opt/rfc-app/frontend/dist/
sudo chown -R rfc-app:rfc-app /opt/rfc-app/frontend/dist
```

Or build on the host directly if Node is available:

```sh
cd /opt/rfc-app/frontend && sudo -u rfc-app npm install
sudo -u rfc-app npm run build
```

### 3.3 Write `.env`

```sh
sudo -u rfc-app cp /opt/rfc-app/backend/.env.example /opt/rfc-app/backend/.env
sudoedit /opt/rfc-app/backend/.env    # set every value
```

Required values for production:

```ini
GITEA_URL=https://git.wiggleverse.org
GITEA_BOT_USER=rfc-bot
GITEA_BOT_TOKEN=<the token from step 2.1>
GITEA_ORG=wiggleverse
META_REPO=meta

OAUTH_CLIENT_ID=<from step 2.3>
OAUTH_CLIENT_SECRET=<from step 2.3>

APP_URL=https://rfc.wiggleverse.org
SECRET_KEY=<32+ random chars; generate with `openssl rand -hex 32`>
OWNER_GITEA_LOGIN=ben.stull
GITEA_WEBHOOK_SECRET=<random; generate with `openssl rand -hex 32`>

DATABASE_PATH=/opt/rfc-app/backend/data/rfc-app.db

# Optional — chat is disabled until at least one is set:
ENABLED_MODELS=claude
ANTHROPIC_API_KEY=
GOOGLE_API_KEY=
OPENAI_API_KEY=
```

Lock the file down — it carries secrets:

```sh
sudo chmod 600 /opt/rfc-app/backend/.env
sudo chown rfc-app:rfc-app /opt/rfc-app/backend/.env
```

### 3.4 Seed the meta repo

This creates `wiggleverse/meta` on Gitea, populates the hand-authored
files, and registers the webhook against `APP_URL/api/webhooks/gitea`.

```sh
sudo -u rfc-app -H bash -c \
  'cd /opt/rfc-app/backend && .venv/bin/python ../scripts/seed_meta_repo.py'
```

Re-running is safe; every step is upsert-shaped.

---

## 4. Web server side

### 4.1 nginx vhost

```sh
sudo cp /opt/rfc-app/deploy/nginx/rfc.wiggleverse.org.conf \
    /etc/nginx/sites-available/rfc.wiggleverse.org
sudo ln -s /etc/nginx/sites-available/rfc.wiggleverse.org \
    /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx
```

Make sure the nginx user can read `/opt/rfc-app/frontend/dist`. The
simplest path: add the nginx user (usually `www-data`) to the
`rfc-app` group and chmod the dist tree group-readable:

```sh
sudo usermod -a -G rfc-app www-data
sudo chmod -R g+rX /opt/rfc-app/frontend/dist
sudo systemctl reload nginx
```

### 4.2 Let's Encrypt cert

```sh
sudo certbot --nginx -d rfc.wiggleverse.org
```

Certbot rewrites the vhost in place to add the 443 listener and
certificate directives. After it finishes, `https://rfc.wiggleverse.org`
serves but the backend isn't up yet — the next step starts it.

---

## 5. systemd

```sh
sudo cp /opt/rfc-app/deploy/systemd/rfc-app.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now rfc-app
sudo systemctl status rfc-app
```

Watch the logs:

```sh
sudo journalctl -u rfc-app -f
```

Expected startup line: `RFC app started — meta repo wiggleverse/meta`.

---

## 6. Smoke test

In a browser at `https://rfc.wiggleverse.org`:

1. The landing page renders. (Slice 1 placeholder; Slice 7 polishes.)
2. Click **Sign in with Gitea** → OAuth round-trip → you land on the
   catalog. (Empty on first visit — no RFCs yet.)
3. Click **+ Propose New RFC**, fill in title/slug/pitch, submit.
   The pending-ideas disclosure shows the new PR.
4. Click the PR row, then **Merge proposal**. The catalog refreshes
   with the super-draft.
5. Optional: seed an active RFC for §8 testing (see
   [README.md](../README.md#seeding-an-active-rfc-for-8-testing)).

If anything misfires, the troubleshooting section below covers the
common failure modes.

---

## 7. Updating after a push

```sh
sudo -u rfc-app git -C /opt/rfc-app pull
sudo -u rfc-app /opt/rfc-app/backend/.venv/bin/pip install \
    -r /opt/rfc-app/backend/requirements.txt
# Rebuild the frontend locally and rsync dist/ as in step 3.2.
sudo systemctl restart rfc-app
```

The §5 schema migrations run on startup and are append-only, so a
restart is the entire deploy. No reverse-migration story for now —
add one when the schema starts breaking back-compat (deferred until
Slice 8 hardening).

---

## Troubleshooting

- **`systemctl status rfc-app` shows `RuntimeError: Required
  environment variable ... is not set`.** The `.env` is missing a
  value, or `EnvironmentFile=` in the systemd unit isn't finding it.
  Confirm `/opt/rfc-app/backend/.env` exists and is mode 0600 owned
  by `rfc-app`.
- **OAuth callback returns "Invalid state".** The redirect URI in
  Gitea must match `APP_URL/auth/callback` exactly. Confirm it's
  `https://rfc.wiggleverse.org/auth/callback`.
- **The catalog stays empty after a merge.** Check the webhook:
  `journalctl -u rfc-app | grep webhook`. Gitea's
  **Settings → Webhooks → Recent Deliveries** on the meta repo shows
  the delivery status; the reconciler will catch up within 5 minutes
  anyway.
- **`502 Bad Gateway` on /api/* or /auth/*.** uvicorn isn't running
  or isn't bound to `127.0.0.1:8000`. `systemctl status rfc-app`.
- **`403` from nginx on static assets.** The nginx user can't read
  `/opt/rfc-app/frontend/dist`. Apply the chmod from step 4.1.
- **OAuth works, but the user can't propose.** The `users` row was
  created with role `contributor`; only `OWNER_GITEA_LOGIN`'s login
  gets `owner` on first sign-in. Confirm `.env` has the right value
  and you signed in with that account.
