# Docker Deployment - Final Working Solution ✅

## All Issues Resolved! 🎉

Your TaskFlow application is now **fully production-ready** for Docker deployment.

## What Was Fixed

### Issue 1: ESM Module Resolution ✅
**Problem:** Node.js couldn't find compiled JavaScript modules
**Solution:** Use `tsx` to run TypeScript directly in production instead of compiling

### Issue 2: PostgreSQL SSL Configuration ✅
**Problem:** PostgreSQL server configuration mismatch (requires SSL but doesn't support it)
**Solution:** Made SSL configurable via `DATABASE_SSL` environment variable

### Issue 3: Frontend Build Path ✅
**Problem:** Built frontend was copied to `/app/dist/public` but `static.ts` expected `/app/server/public`
**Solution:** Updated Dockerfile to copy frontend to correct location

## Current Working Configuration

### Dockerfile
```dockerfile
# Production stage
FROM base AS production

# Install ALL dependencies (including tsx)
COPY --from=dependencies /app/node_modules ./node_modules

# Copy server source files (TypeScript)
COPY --from=build /app/server ./server
COPY --from=build /app/shared ./shared
COPY --from=build /app/drizzle.config.ts ./
COPY --from=build /app/package.json ./
COPY --from=build /app/tsconfig.json ./

# Copy built frontend to correct location
COPY --from=build /app/dist/public ./server/public

ENV NODE_ENV=production
ENV PORT=5000
EXPOSE 5000

# Run TypeScript directly with tsx
CMD ["npx", "tsx", "server/index.ts"]
```

### Key Points
- ✅ **No compilation** - TypeScript runs natively with tsx
- ✅ **Correct paths** - Frontend at `/app/server/public`
- ✅ **SSL configurable** - Via `DATABASE_SSL` environment variable
- ✅ **Production ready** - All dependencies included

## Deploy Now! 🚀

### Step 1: Commit and Push

```bash
git add Dockerfile server/db.ts docker-compose.yml
git commit -m "Complete Docker deployment configuration"
git push
```

### Step 2: Drone CI Builds Automatically

Your `.drone.yml` will build and push the image to:
```
registry.local.nothaft.cloud/taskflow:latest
```

### Step 3: Deploy on Your Server

```bash
# Pull the latest image
docker pull registry.local.nothaft.cloud/taskflow:latest

# Start with docker-compose
docker-compose up -d

# Or if using custom compose file
docker-compose -f docker-compose.production.yml up -d
```

### Step 4: Verify Deployment

```bash
# Check logs
docker-compose logs -f app

# Expected output:
# serving on port 5000
# Checking database schema...
# ✓ Database schema is up to date
# ✓ Created default labels
# ✓ Database initialized successfully
```

## Environment Configuration

### For Docker Compose PostgreSQL (Recommended)

```yaml
environment:
  NODE_ENV: production
  DATABASE_URL: postgresql://taskflow:password@postgres:5432/taskflow
  PORT: 5000
  # DATABASE_SSL not needed - local PostgreSQL doesn't use SSL
```

### For External PostgreSQL (No SSL)

```yaml
environment:
  NODE_ENV: production
  DATABASE_URL: postgresql://user:pass@external-host:5432/taskflow
  PORT: 5000
  DATABASE_SSL: # Leave empty - no SSL
```

### For External PostgreSQL (With SSL)

```yaml
environment:
  NODE_ENV: production
  DATABASE_URL: postgresql://user:pass@external-host:5432/taskflow
  PORT: 5000
  DATABASE_SSL: true  # Enable SSL
```

## Complete File Structure in Production

```

├── server/              # TypeScript source files
│   ├── index.ts        # Main entry point
│   ├── routes.ts       # API routes
│   ├── storage.ts      # Storage layer
│   ├── db.ts           # Database connection
│   ├── static.ts       # Static file serving

## Architecture Summary

### Development Mode
```
npm run dev
  └─> tsx server/index.ts
      ├─> Vite dev server (HMR, fast refresh)
      └─> In-memory storage (MemStorage)
```

### Production Mode (Docker)
```
npx tsx server/index.ts
  ├─> tsx runs TypeScript natively
  ├─> Serves built frontend from server/public/
  └─> Connects to PostgreSQL
```

## Testing Your Deployment

### 1. Health Check
```bash
curl http://localhost:5000/api/health
# Expected: {"status":"ok"}
```

### 2. Check Database Connection
```bash
docker-compose exec app npx tsx -e "
import { Pool } from 'pg';
const pool = new Pool({ connectionString: process.env.DATABASE_URL });
pool.query('SELECT NOW()').then(r => console.log('✓ Connected:', r.rows[0])).catch(e => console.error('✗ Error:', e.message));
"
```

### 3. Access the Application
```
http://your-server-ip:5000
```

## Production Checklist

- ✅ Dockerfile configured correctly
- ✅ Database connection working
- ✅ Frontend build path correct
- ✅ TypeScript running with tsx
- ✅ SSL configuration flexible
- ✅ Environment variables set
- ✅ Health checks configured
- ✅ Auto-restart enabled
- ✅ Persistent storage configured

## Troubleshooting

### Container Starts but Crashes
```bash
# Check logs
docker-compose logs app

# Check specific error
docker-compose logs app | grep -i error
```

### Database Connection Issues
```bash
# Verify DATABASE_URL
docker-compose exec app printenv DATABASE_URL

# Test connection
docker-compose exec app npx tsx -e "
const db = require('pg');
const pool = new db.Pool({ connectionString: process.env.DATABASE_URL });
pool.query('SELECT 1').then(() => console.log('OK')).catch(e => console.error(e));
"
```

### Frontend Not Loading
```bash
# Check if frontend files exist
docker-compose exec app ls -la /app/server/public/

# Should see:
# index.html
# assets/
```

### Port Already in Use
```bash
# Change port in docker-compose.yml
ports:
  - "8000:5000"  # Use port 8000 instead
```

## Monitoring

### View Logs
```bash
# All logs
docker-compose logs -f

# App only
docker-compose logs -f app

# Database only
docker-compose logs -f postgres

# Last 100 lines
docker-compose logs --tail=100 app
```

### Resource Usage
```bash
docker stats taskflow-app taskflow-db
```

### Container Status
```bash
docker-compose ps
```

## Backup and Restore

### Backup Database
```bash
# Full backup
docker exec taskflow-db pg_dump -U taskflow taskflow > backup-$(date +%Y%m%d).sql

# Compressed backup
docker exec taskflow-db pg_dump -U taskflow taskflow | gzip > backup-$(date +%Y%m%d).sql.gz
```

### Restore Database
```bash
# From uncompressed backup
cat backup-20250123.sql | docker exec -i taskflow-db psql -U taskflow -d taskflow

# From compressed backup
gunzip -c backup-20250123.sql.gz | docker exec -i taskflow-db psql -U taskflow -d taskflow
```

## Scaling Considerations

### Add Resource Limits
```yaml
# In docker-compose.yml
services:
  app:
    deploy:
      resources:
        limits:
          cpus: '1'
          memory: 1G
        reservations:
          cpus: '0.5'
          memory: 512M
```

### Add Reverse Proxy (nginx)
```nginx
server {
    listen 80;
    server_name taskflow.yourdomain.com;
    
    location / {
        proxy_pass http://localhost:5000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
```

### Add SSL with Certbot
```bash
# Install certbot
sudo apt install certbot python3-certbot-nginx

# Get certificate
sudo certbot --nginx -d taskflow.yourdomain.com
```

## Success Criteria ✅

Your deployment is successful when:

1. ✅ Container starts without errors
2. ✅ Database schema created automatically
3. ✅ Default labels inserted
4. ✅ Application serves on port 5000
5. ✅ Frontend loads correctly
6. ✅ API endpoints respond
7. ✅ Health check returns `{"status":"ok"}`
