# Deployment Guide for parking.rocketscale.it

## Prerequisites

- org-stack running on rocky@rocketscale.it
- Git repository on git.rocketscale.it (optional, can use rsync)

## Directory Structure

Parking is deployed as a **separate directory** alongside org-stack:

```
~/
├── org-stack/          # Main stack (Caddy, Authelia, LLDAP, etc.)
│   ├── compose.yml
│   ├── Caddyfile
│   ├── authelia/
│   └── .env
│
└── org-parking/        # Parking app (separate)
    ├── compose.yml     # Production compose (connects to org-stack network)
    ├── .env            # Own .env with PARKING_SECRET_KEY
    ├── Dockerfile
    └── ...
```

## Step 1: Deploy to Server

Option A - Using rsync (recommended for development):
```bash
# From development machine
rsync -avz --exclude '.git' --exclude '__pycache__' --exclude '*.pyc' \
  --exclude '.env' --exclude 'data/' --exclude '*.db' --exclude '.venv/' \
  /path/to/org-parking/ rocky@rocketscale.it:~/org-parking/
```

Option B - Using git:
```bash
ssh rocky@rocketscale.it
cd ~
git clone git@git.rocketscale.it:rocky/parking-manager.git org-parking
```

## Step 2: Create Production compose.yml

Create `~/org-parking/compose.yml` on the server:

```yaml
services:
  parking:
    build: .
    container_name: parking
    restart: unless-stopped
    volumes:
      - parking_data:/app/data
    environment:
      - SECRET_KEY=${PARKING_SECRET_KEY}
      - DATABASE_PATH=/app/data/parking.db
      - AUTHELIA_ENABLED=true
      - ALLOWED_ORIGINS=https://parking.rocketscale.it
      - SMTP_HOST=${SMTP_HOST:-}
      - SMTP_PORT=${SMTP_PORT:-587}
      - SMTP_USER=${SMTP_USER:-}
      - SMTP_PASSWORD=${SMTP_PASSWORD:-}
      - SMTP_FROM=${SMTP_FROM:-}
    networks:
      - org-network
    healthcheck:
      test: ["CMD", "python", "-c", "import urllib.request; urllib.request.urlopen('http://localhost:8000/health')"]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 10s

volumes:
  parking_data:

networks:
  org-network:
    external: true
    name: org-stack_org-network
```

## Step 3: Create .env File

Create `~/org-parking/.env` with a secret key:

```bash
cd ~/org-parking
python3 -c "import secrets; print(f'PARKING_SECRET_KEY={secrets.token_hex(32)}')" > .env
```

**Note**: Each directory needs its own `.env` file since docker compose only reads from the current directory.

## Step 4: Add to Caddyfile

Add to `~/org-stack/Caddyfile`:

```
# Parking Manager - Protected by Authelia
parking.rocketscale.it {
    import auth
    reverse_proxy parking:8000
}
```

## Step 5: Add Authelia Access Control Rule

**Important**: Authelia's `access_control` must include parking.rocketscale.it or you'll get 403 Forbidden.

Edit `~/org-stack/authelia/configuration.yml` and add to the `access_control.rules` section:

```yaml
access_control:
  default_policy: deny
  rules:
    # ... existing rules ...

    # Parking Manager - require authentication
    - domain: parking.rocketscale.it
      policy: one_factor
```

After editing, restart Authelia:
```bash
cd ~/org-stack
docker compose restart authelia
```

## Step 6: Create LLDAP Group

In lldap (https://ldap.rocketscale.it):

1. Create group: `parking_admins`
2. Add yourself (or whoever should be admin) to this group

**Role Management:**
- `parking_admins` group → **admin** role (synced from LLDAP on each login)
- **manager** role → assigned by admin in the app UI (Manage Users page)
- **employee** role → default for all other users

The admin can promote users to manager and assign offices via the Manage Users page.

## Step 7: Build and Deploy

```bash
# Build and start parking service
cd ~/org-parking
docker compose build parking
docker compose up -d

# Reload Caddy to pick up new domain (from org-stack)
cd ~/org-stack
docker compose exec caddy caddy reload --config /etc/caddy/Caddyfile

# Check logs
cd ~/org-parking
docker compose logs -f parking
```

## Step 8: Verify

1. Go to https://parking.rocketscale.it
2. You should be redirected to Authelia for login
3. After login, you should see the parking app
4. Your user should be auto-created with `admin` role (if in parking-admins group)

## Troubleshooting

### 403 Forbidden from Authelia
- Authelia's `access_control` doesn't have a rule for parking.rocketscale.it
- Add the domain to `~/org-stack/authelia/configuration.yml` (see Step 6)
- Restart Authelia: `docker compose restart authelia`

### 401 Unauthorized
- Check Authelia headers are being passed
- Check `docker compose logs authelia`

### Login redirect loop (keeps redirecting to /login)
- Frontend JS must use async auth checking for Authelia mode
- The `api.requireAuth()` must call `/api/auth/me` endpoint (not check localStorage)
- Ensure all page JS files use: `currentUser = await api.requireAuth();`

### User has wrong role
- **Admin role**: Verify user is in `parking_admins` LLDAP group (synced on each login)
- **Manager role**: Must be assigned by admin via Manage Users page (not from LLDAP)
- **Employee role**: Default for users not in `parking_admins` group

### Database errors
- Check volume mount: `docker compose exec parking ls -la /app/data`
- Check permissions: `docker compose exec parking id`

## Architecture Notes

### Authelia Integration
The app supports two authentication modes:
1. **JWT mode** (standalone): Users login via `/login`, get JWT token stored in localStorage
2. **Authelia mode** (SSO): Authelia handles login, passes headers to backend

When `AUTHELIA_ENABLED=true`:
- Backend reads user info from headers: `Remote-User`, `Remote-Email`, `Remote-Name`, `Remote-Groups`
- Users are auto-created on first login
- Roles are synced from LLDAP groups on each request
- Frontend calls `/api/auth/me` to get user info (backend reads headers)

### Role Management

Only the **admin** role is synced from LLDAP:
```python
AUTHELIA_ADMIN_GROUP = "parking_admins"   # → role: admin
```

Other roles are managed within the app:
- **manager**: Assigned by admin via Manage Users page
- **employee**: Default role for all non-admin users

This separation allows:
- LLDAP to control who has admin access
- App admin to assign manager roles and office assignments without LLDAP changes
