# Deployment Architecture - Complete Modernization Summary

**Date:** January 17, 2026  
**Status:** ✅ COMPLETE & PRODUCTION READY

## What Was Accomplished

### 1. **Code Deployment Modernized (Option 1)**
- ✅ Moved code into Docker image (no volume override)
- ✅ Eliminated init-data.sh manual step
- ✅ Cleaner separation: code (immutable image) vs data (persistent volumes)

### 2. **Legacy Code Cleaned**
- ✅ Archived groups feature (not used, replaced by playlists)
- ✅ Archived legacy playlist routes (redirects to content area now)
- ✅ Removed unused imports and API endpoints

### 3. **Persistence Unified in /data Folder**
- ✅ Moved nginx.conf to data/
- ✅ Moved nginx-custom-domains.conf to data/
- ✅ All runtime files now in single data/ folder
- ✅ Clear separation: source code (git) vs runtime data (data/)

---

## Complete Architecture (NOW)

### Repository Structure (Source Code)
```
/srv/digiserver-v2/
├── app/                    # Flask application (BUILT INTO DOCKER IMAGE)
├── migrations/             # Database migrations (BUILT INTO DOCKER IMAGE)
├── Dockerfile              # Copies everything above into image
├── docker-compose.yml      # Container orchestration
├── requirements.txt        # Python dependencies
├── .gitignore
└── [other source files]    # All built into image
```

### Container Runtime Structure (/data folder)
```
data/
├── instance/               # Database & config (PERSISTENT)
│   ├── digiserver.db
│   └── server.log
├── uploads/                # User uploads (PERSISTENT)
│   ├── app/static/uploads/
│   └── [user files]
├── nginx.conf              # Nginx main config (PERSISTENT) ✅ NEW
├── nginx-custom-domains.conf # Custom domains (PERSISTENT) ✅ NEW
├── nginx-ssl/              # SSL certificates (PERSISTENT)
├── nginx-logs/             # Web server logs (PERSISTENT)
├── certbot/                # Let's Encrypt data (PERSISTENT)
├── caddy-config/           # Caddy configurations
└── [other runtime files]
```

### Docker Container Volumes (No Code Mounts!)
```yaml
digiserver-app:
  volumes:
    - ./data/instance:/app/instance          # DB
    - ./data/uploads:/app/app/static/uploads # Uploads
    # ✅ NO CODE MOUNT - code is in image!

nginx:
  volumes:
    - ./data/nginx.conf:/etc/nginx/nginx.conf                    # ✅ FROM data/
    - ./data/nginx-custom-domains.conf:/etc/nginx/conf.d/custom-domains.conf  # ✅ FROM data/
    - ./data/nginx-ssl:/etc/nginx/ssl                            # Certs
    - ./data/nginx-logs:/var/log/nginx                           # Logs
    - ./data/certbot:/var/www/certbot                            # ACME
```

---

## Deployment Flow (NOW)

### Fresh Deployment
```bash
cd /srv/digiserver-v2

# 1. Prepare data folder
mkdir -p data/{instance,uploads,nginx-ssl,nginx-logs,certbot}
cp nginx.conf data/
cp nginx-custom-domains.conf data/

# 2. Build image (includes app code)
docker-compose build

# 3. Deploy
docker-compose up -d

# 4. Initialize database (automatic on first run)
```

### Code Updates
```bash
# 1. Get new code
git pull

# 2. Rebuild image (code change → new image)
docker-compose build

# 3. Deploy new version
docker-compose up -d
```

### Configuration Changes
```bash
# Edit config in data/ (PERSISTENT)
nano data/nginx.conf
nano data/nginx-custom-domains.conf

# Reload without full restart
docker-compose restart nginx
```

## Key Improvements

### ✅ Deployment Simplicity
| Aspect | Before | After |
|--------|--------|-------|
| Manual setup step | init-data.sh required | None - auto in image |
| Config location | Mixed (root + data/) | Single (data/) |
| Code update process | Copy + restart | Build + restart |
| Backup strategy | Multiple locations | Single data/ folder |

### ✅ Production Readiness
- Immutable code in image (reproducible deployments)
- Version-controlled via image tags
- Easy rollback: use old image tag
- CI/CD friendly: build → test → deploy

### ✅ Data Safety
- All persistent data in one folder
- Easy backup: `tar czf backup.tar.gz data/`
- Easy restore: `tar xzf backup.tar.gz`
- Clear separation from source code

### ✅ Repository Cleanliness
```
Before:                      After:
./nginx.conf    ❌          ./data/nginx.conf        ✅
./nginx-custom-domains.conf  ./data/nginx-custom-domains.conf
./init-data.sh  ❌          (archived as deprecated)
./app/          ✅          ./app/           ✅ (in image)
./data/app/     ❌ (redundant) [none - in image]
```

## Next Steps (Optional Cleanup)

### Option A: Keep Root Files (Safe)
```bash
# Keep nginx.conf and nginx-custom-domains.conf in root as backups
# They're not used but serve as reference
# Already ignored by .gitignore
```

### Option B: Clean Repository (Recommended)
```bash
# Remove root nginx files (already in data/)
rm nginx.conf
rm nginx-custom-domains.conf

# Add to .gitignore if needed:
echo "nginx.conf" >> .gitignore
echo "nginx-custom-domains.conf" >> .gitignore
```

---

## Production Deployment

### Recommended Workflow
```bash
# 1. Code changes
git commit -m "feature: add new UI"

# 2. Build and test
docker-compose build
docker-compose up -d
# [run tests]

# 3. Tag version
git tag v1.2.3
docker tag digiserver-v2-digiserver-app:latest digiserver-v2-digiserver-app:v1.2.3

# 4. Push to registry
docker push myregistry/digiserver:v1.2.3

# 5. Deploy
docker pull myregistry/digiserver:v1.2.3
docker-compose up -d
```
