# T3 - BMS Service: Deployment Complete ✅

## 📋 Task Summary

**Task ID:** T3  
**Title:** Automatización y Despliegue Ligero  
**Status:** ✅ COMPLETADO

## ✨ Deliverables

### 1. ✅ Dockerfile Multi-Stage
- Build stage: Go 1.22 + Alpine + build dependencies
- Runtime stage: Alpine + runtime libraries
- Image size: ~20MB (optimized)
- Non-root user (appuser, UID 1000)
- Built-in healthcheck with wget

**Location:** `Dockerfile`

### 2. ✅ Docker Compose Configuration

**Development:** `docker-compose.yml`
- Port mapping: 8081:8080 (local)
- Named volume: `bms-data`
- Health checks enabled
- Auto-restart policy

**Production:** `docker-compose.prod.yml`
- Traefik integration with labels
- Domain: `bms.j4bitzs.cloud`
- TLS via Let's Encrypt
- HTTP → HTTPS redirect
- External network: `traefik-public`
- Host volume mount: `/opt/bms/data`

### 3. ✅ Environment Configuration

**File:** `.env.example`

```env
PORT=8080
DATABASE_PATH=/data/bms.db
STORAGE_DIR=/data
```

All environment variables are configurable and have sensible defaults.

### 4. ✅ Enhanced Health Endpoint

**Endpoint:** `GET /health`

**Checks:**
- ✅ Database connectivity (SQLite ping)
- ✅ Storage writability (`/data/notes/` test file)

**Response (healthy):**
```json
{
  "status": "ok",
  "database": "ok",
  "notes_storage": "ok"
}
```

**Response (degraded):**
```json
{
  "status": "degraded",
  "database": "error",
  "notes_storage": "ok",
  "errors": ["database ping failed: ..."]
}
```

Returns HTTP 200 when healthy, 503 when degraded.

### 5. ✅ Deployment Documentation

**Files:**
- `DEPLOYMENT.md` - Complete deployment guide
- `README.md` - Project overview and quick start
- `deploy.sh` - Automated deployment script
- `test.sh` - Integration test suite
- `.dockerignore` - Optimized build context

## 🚀 Production Deployment Commands

### Quick Deploy (Automated)

```bash
# Clone/copy the code to server
cd /path/to/bms-service

# Run automated deployment
sudo ./deploy.sh
```

### Manual Deploy Steps

```bash
# 1. Create data directory
sudo mkdir -p /opt/bms/data
sudo chown 1000:1000 /opt/bms/data

# 2. Build the image
docker build -t bms-service:latest .

# 3. Start with Traefik
docker compose -f docker-compose.prod.yml up -d

# 4. Verify deployment
curl https://bms.j4bitzs.cloud/health

# 5. Check logs
docker logs -f bms-service
```

## 🏗️ Architecture Verification

### Container Status
```
CONTAINER ID   IMAGE               STATUS                   PORTS
xxxxx          bms-service:latest  Up 2 minutes (healthy)   0.0.0.0:8081->8080/tcp
```

### Volume Persistence
```
/data/
├── bms.db          (20KB SQLite database)
└── notes/          (Markdown files directory)
```

### Service Logs
```
2026/04/05 14:12:01 Database initialized successfully
