1. ✅ Commit code changes to version control
|
||||
2. ✅ Set proper environment variables

## ⚠️ ISSUES REQUIRING ATTENTION
|
||||
|
||||
### Issue #1: Hardcoded Default Values in Config 🔴
|
||||
|
||||
**Location**: `app/config.py`
|
||||
|
||||
**Problem**:
|
||||
```python
|
||||
SECRET_KEY = os.getenv('SECRET_KEY', 'dev-secret-key-change-in-production')
|
||||
DEFAULT_ADMIN_PASSWORD = os.getenv('ADMIN_PASSWORD', 'Initial01!')
|
||||
```
|
||||
|
||||
**Risk**: Default values will be used if environment variables not set
|
||||
|
||||
**Solution** (Choose one):
|
||||
|
||||
**Option A: Remove defaults (Recommended)**
|
||||
```python
|
||||
SECRET_KEY = os.getenv('SECRET_KEY') # Fails fast if not set
|
||||
DEFAULT_ADMIN_PASSWORD = os.getenv('ADMIN_PASSWORD')
|
||||
```
|
||||
|
||||
**Option B: Use stronger defaults**
|
||||
```python
|
||||
import secrets
|
||||
SECRET_KEY = os.getenv('SECRET_KEY', secrets.token_urlsafe(32))
|
||||
DEFAULT_ADMIN_PASSWORD = os.getenv('ADMIN_PASSWORD', secrets.token_urlsafe(16))
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Issue #2: Uncommitted Changes 🟡
|
||||
|
||||
**Current status**: 7 uncommitted changes
|
||||
|
||||
```
|
||||
M app/app.py (CORS implementation)
|
||||
M app/blueprints/api.py (Certificate endpoint)
|
||||
M app/config.py (Session security)
|
||||
M app/extensions.py (CORS support)
|
||||
M nginx.conf (CORS headers)
|
||||
M requirements.txt (Added cryptography)
|
||||
? old_code_documentation/ (New documentation)
|
||||
```
|
||||
|
||||
**Action Required**:
|
||||
```bash
|
||||
cd /srv/digiserver-v2
|
||||
git add -A
|
||||
git commit -m "HTTPS improvements: Enable CORS, fix player connections, add security headers"
|
||||
git log --oneline -1
|
||||
```

|
||||
|
||||
## 🚀 PRODUCTION DEPLOYMENT CHECKLIST
|
||||
|
||||
### Pre-Deployment (Execute in order)
|
||||
|
||||
- [ ] **1. Commit all changes**
|
||||
```bash
|
||||
git status
|
||||
git add -A
|
||||
git commit -m "Production-ready: HTTPS/CORS fixes"
|
||||
```
|
||||
|
||||
- [ ] **2. Set environment variables**
|
||||
Create `.env` file or configure in deployment system:
|
||||
```bash
|
||||
SECRET_KEY=<generate-long-random-string>
|
||||
ADMIN_USERNAME=admin
|
||||
ADMIN_PASSWORD=<strong-password>
|
||||
ADMIN_EMAIL=admin@yourdomain.com
|
||||
DATABASE_URL=sqlite:////path/to/db # or PostgreSQL
|
||||
FLASK_ENV=production
|
||||
DOMAIN=your-domain.com
|
||||
EMAIL=admin@your-domain.com
|
||||
```
|
||||
|
||||
- [ ] **3. Update docker-compose.yml environment section**
|
||||
```yaml
|
||||
environment:
|
||||
- FLASK_ENV=production
|
||||
- SECRET_KEY=${SECRET_KEY}
|
||||
- ADMIN_USERNAME=${ADMIN_USERNAME}
|
||||
- ADMIN_PASSWORD=${ADMIN_PASSWORD}
|
||||
- DATABASE_URL=${DATABASE_URL}
|
||||
- DOMAIN=${DOMAIN}
|
||||
- EMAIL=${EMAIL}
|
||||
```
|
||||
|
||||
- [ ] **4. SSL Certificate Strategy**
|
||||
|
||||
**Option A: Keep Self-Signed (Quick)**
|
||||
- Current certificate valid until 2027
|
||||
- Players must accept/trust cert
|
||||
- Suitable for internal networks
|
||||
|
||||
**Option B: Use Let's Encrypt (Recommended)**
|
||||
- Install certbot: `apt install certbot`
|
||||
- Generate cert: `certbot certonly --standalone -d yourdomain.com`
|
||||
- Copy to: `data/nginx-ssl/`
|
||||
- Auto-renew with systemd timer
|
||||
|
||||
**Option C: Use Commercial Certificate**
|
||||
- Purchase from provider
|
||||
- Copy cert and key to `data/nginx-ssl/`
|
||||
- Update nginx.conf paths if needed
|
||||
|
||||
- [ ] **5. Database initialization**
|
||||
```bash
|
||||
# First run will create database
|
||||
docker-compose up -d
|
||||
# Run migrations
|
||||
docker-compose exec digiserver-app flask db upgrade
|
||||
```
|
||||
|
||||
- [ ] **6. Test deployment**
|
||||
```bash
|
||||
# Health check
|
||||
curl -k https://your-server/api/health
|
||||
|
||||
# CORS headers
|
||||
curl -i -k https://your-server/api/playlists
|
||||
|
||||
# Login page
|
||||
curl -k https://your-server/login
|
||||
```
|
||||
|
||||
- [ ] **7. Backup database**
|
||||
```bash
|
||||
docker-compose exec digiserver-app \
|
||||
cp instance/dashboard.db /backup/dashboard.db.bak
|
||||
```
|
||||
|
||||
- [ ] **8. Configure monitoring**
|
||||
- Set up log aggregation
|
||||
- Configure alerts for container restarts
|
||||
- Monitor disk space for uploads
|
||||
|
||||
### Post-Deployment
|
||||
|
||||
- [ ] Verify player connections work
|
||||
- [ ] Test playlist fetching
|
||||
- [ ] Monitor error logs for 24 hours
|
||||
- [ ] Verify database backups are working
|
||||
- [ ] Set up SSL renewal automation

||||
- [ ] Restrict database access
|
||||
|
||||
6. **Monitoring**
