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)

└── [other runtime files]

Docker Container Volumes (No Code Mounts!)

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

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

# 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

# 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]

---

Checklist: All Changes Deployed ✅

• docker-compose.yml updated (no code volume mount)
• Dockerfile enhanced (code baked in)
• init-data.sh archived (no longer needed)
• Groups feature archived (legacy/unused)
• Playlist routes simplified (legacy redirects)
• Nginx configs moved to data/ folder
• All containers running healthy
• HTTP/HTTPS working
• Database persistent
• Uploads persistent
• Configuration persistent

---

Testing Results ✅

✓ Docker build: SUCCESS
✓ Container startup: SUCCESS
✓ Flask app responding: SUCCESS
✓ Nginx HTTP (port 80): SUCCESS
✓ Nginx HTTPS (port 443): SUCCESS
✓ Database accessible: SUCCESS
✓ Uploads persisting: SUCCESS
✓ Logs persisting: SUCCESS
✓ Config persistence: SUCCESS

Next Steps (Optional Cleanup)

Option A: Keep Root Files (Safe)

# 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)

# 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

# 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
