Rewrite QUICK_DEPLOYMENT.md for Caddy-based architecture

- Replace Nginx references throughout with Caddy
- Update architecture diagram to show Caddy
- Update container details (caddy:2-alpine, ports 8080/8443)
- Update volume paths (caddy-data, caddy-config, caddy-logs)
- Add rebuild guide for code changes (docker build + restart)
- Add quick-test method (docker cp + pkill -HUP)
- Simplify commands section (docker compose not docker-compose)
- Remove Nginx-specific troubleshooting
- Add Caddy validation and reload commands

DigiServer is deployed using Docker Compose with the following architecture:
```
Internet (User)
Internet (User) — Port 8080 (HTTP) / 8443 (HTTPS)
Nginx Reverse Proxy (Port 80/443)
Caddy Reverse Proxy (auto HTTPS, gzip, security headers)
Internal Docker Network
Internal Docker Network (digiserver-network)
Flask App (Gunicorn on Port 5000)
SQLite Database
```
Caddy is used instead of Nginx because it:
- **Auto-provisions Let's Encrypt certificates** — no manual certbot
- **Simpler config** — a `Caddyfile` replaces the verbose `nginx.conf`
- **Built-in HTTP/2, gzip, security headers**
- **Admin API** (port 2019) — Flask reloads Caddy config dynamically
---
## 🚀 Complete Deployment Workflow
## 🚀 Quick Start
### **1️⃣ Clone & Setup**
```bash
# Copy the app folder from repository
git clone <repository>
cd digiserver-v2
# Copy environment file and modify as needed
cp .env.example .env
# Edit .env with your configuration:
nano .env
```
**Configure in .env:**
```env
SECRET_KEY=your-secret-key-change-this
ADMIN_USERNAME=admin
ADMIN_PASSWORD=your-secure-password
DOMAIN=your-domain.com
EMAIL=admin@your-domain.com
IP_ADDRESS=192.168.0.111
```
---
### **2️⃣ Deploy via Script**
### **2️⃣ Start Containers**
```bash
# Run the deployment script
./deploy.sh
docker compose up -d
```
This automatically:
1.Creates `data/` directories (instance, uploads, nginx-ssl, etc.)
2. ✅ Copies nginx configs from repo root to `data/`
3. ✅ Starts Docker containers
4. ✅ Initializes database
5. ✅ Runs all migrations
6. ✅ Configures HTTPS with SSL certificates
7. ✅ Displays access information
1.Builds the Flask app image from `Dockerfile`
2. ✅ Creates persistent data directories (`data/instance`, `data/uploads`, etc.)
3. ✅ Starts Caddy reverse proxy on ports **8080** (HTTP) and **8443** (HTTPS)
4. ✅ Initializes the database on first run (auto-creates admin user)
5. ✅ Runs all required migrations
**Output shows:**
- Access URLs (HTTP/HTTPS)
- Default credentials
- Next steps for configuration
**Access the app at:** `http://localhost:8080`
---
### **3️⃣ Network Migration (When Network Changes)**
When moving the server to a different network with a new IP:
```bash
# Migrate to the new network IP
./migrate_network.sh 10.55.150.160
# Optional: with custom hostname
./migrate_network.sh 10.55.150.160 digiserver-secured
### **3️⃣ First-Time Login**
```
This automatically:
1. ✅ Regenerates SSL certificates for new IP
2. ✅ Updates database HTTPS configuration
3. ✅ Restarts nginx and app containers
4. ✅ Verifies HTTPS connectivity
---
### **4️⃣ Normal Operations**
**Restart containers:**
```bash
docker compose restart
```
**Stop containers:**
```bash
docker compose down
```
**View logs:**
```bash
docker compose logs -f
```
**View container status:**
```bash
docker compose ps
URL: http://localhost:8080
Username: admin
Password: admin123
```
⚠️ **CHANGE PASSWORD IMMEDIATELY IN PRODUCTION!**

## 🔧 Deployment Steps Explained
## 🚀 Full Automated Deployment
### **Step 1: Start Containers**
```bash
docker-compose up -d
./deploy.sh
```
- Builds Flask app image (if needed)
- Starts both containers
- Waits for containers to be healthy
This runs the complete workflow:
1. Creates `data/` directories (`instance`, `uploads`, `caddy-*`)
2. Starts containers (`docker compose up -d`)
3. Initialises database and admin user
4. Runs all database migrations
5. Enables HTTPS via Flask Admin
6. Validates Caddy configuration
7. Prints access URLs and credentials
---
## 🔧 Deployment Steps (Manual)
### **Step 1: Build & Start**
```bash
docker compose up -d
```
- Builds Flask app image (layer cached)
- Creates `digiserver-network` bridge
- Starts `digiserver-app`, then `caddy`
### **Step 2: Database Initialization** (docker-entrypoint.sh)
When Flask container starts:
1. Create required directories
2. Check if database exists
3. If NOT exists:
- Initialize SQLite database (dashboard.db)
- Create admin user from environment variables
4. Start Gunicorn server (4 workers, 120s timeout)
On container start the entrypoint automatically:
1. Creates required directories
2. Checks for existing `dashboard.db`
3. If absent — creates tables and seeds admin user
4. Starts Gunicorn (4 workers, 120s timeout)
### **Step 3: Run Migrations**
```bash
docker-compose exec -T digiserver-app python /app/migrations/[migration_name].py
docker compose exec -T digiserver-app python /app/migrations/<name>.py
```
Applied migrations:
- `add_https_config_table.py` - HTTPS settings
- `add_player_user_table.py` - Player user management
- `add_email_to_https_config.py` - Email configuration
- `migrate_player_user_global.py` - Global settings
Key migrations:
- `add_https_config_table.py` HTTPS settings table
- `add_player_user_table.py` Player user management
- `add_email_to_https_config.py` Email field
- `migrate_player_user_global.py` Global settings
- `add_url_to_content.py` — Web link support
- `add_deployment_fields_to_player.py` — Deployment tracking
### **Step 4: Configure HTTPS**
- SSL certificates stored in `./data/nginx-ssl/`
- Pre-generated self-signed certs for development
- Ready for Let's Encrypt integration
Via Admin UI (recommended):
1. Go to **Admin → HTTPS Config**
2. Enter hostname, domain, email, IP, port
3. Caddy auto-provisions a Let's Encrypt certificate
### **Step 5: Reverse Proxy Routing** (nginx.conf)
```
HTTP (80):
• Redirect all traffic to HTTPS
• Allow ACME challenges for Let's Encrypt
HTTPS (443):
• TLS 1.2+, HTTP/2 enabled
• Proxy all requests to Flask app
• Security headers added
• Gzip compression enabled
• Max upload size: 2GB
• Proxy timeout: 300s
Via CLI:
```bash
docker compose exec -T digiserver-app python /app/https_manager.py enable \
<hostname> <domain> <email> <ip_address> <port>
```
### **Step 6: ProxyFix Middleware** (app/app.py)
Extracts real client information from Nginx headers:
### **Step 5: ProxyFix Middleware** (app/app.py)
Flask extracts real client info from Caddy headers:
- `X-Forwarded-For` → Real client IP
- `X-Forwarded-Proto` → Protocol (http/https)

## 📂 Directory Structure & Persistence
## 🔄 Rebuild After Code Changes
Because the application code is baked into the Docker image, update it with:
```bash
# 1. Rebuild the image
docker build --no-cache -t digiserver-v2-digiserver-app .
# 2. Replace the running container
docker stop digiserver-v2 && docker rm digiserver-v2
docker compose up -d digiserver-app
```
**Quick test (no rebuild)** — copy files into the running container:
```bash
docker cp <local_file> digiserver-v2:/app/<path>
docker exec digiserver-v2 pkill -HUP -f gunicorn
```
---
## 🌐 Network Migration
When the server moves to a different network / IP:
```bash
./migrate_network.sh 10.55.150.160
# Optional: ./migrate_network.sh 10.55.150.160 digiserver-secured
```
This regenerates SSL certificates, updates the database HTTPS config, and restarts both containers.

## 🔒 SSL Certificate Management
## 🔒 HTTPS / SSL
Caddy automatically provisions Let's Encrypt certificates when a public domain is configured. For development with self-signed certificates:
### **Generate New Self-Signed Certificate**
```bash
bash generate_nginx_certs.sh 192.168.0.121 365
docker-compose restart nginx
docker compose restart caddy
```
Parameters:
- `192.168.0.121` - Domain/IP for certificate
- `365` - Certificate validity in days
### **Set Up Let's Encrypt (Production)**
1. Update `DOMAIN` and `EMAIL` in environment
2. Modify `nginx.conf` to enable certbot challenges
3. Run certbot:
```bash
docker run --rm -v $(pwd)/data/certbot:/etc/letsencrypt \
-v $(pwd)/data/nginx-logs:/var/log/letsencrypt \
certbot/certbot certonly --webroot \
-w /var/www/certbot \
-d yourdomain.com \
-m your-email@example.com \
--agree-tos
```
> **Note:** `generate_nginx_certs.sh` has been moved to `old_code_documentation/` but still works.
