## Step 1: Create Dockerfiles

### API Dockerfile
```dockerfile
# docker/api.Dockerfile
FROM node:18-alpine AS builder

WORKDIR /app

# Copy workspace files
COPY package.json pnpm-lock.yaml pnpm-workspace.yaml ./

    gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    # SPA routing - all routes go to index.html
    location / {
        try_files $uri $uri/ /index.html;
    }

    # Cache static assets
    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2|ttf|eot)$ {
        expires 1y;
        add_header Cache-Control "public, immutable";
    }

    # Security headers
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-Content-Type-Options "nosniff" always;
    add_header X-XSS-Protection "1; mode=block" always;
}
```

## Step 2: Docker Compose

```yaml
# docker-compose.yml
version: '3.8'

services:
  mysql:
    image: mysql:8.0
    container_name: voxblog-mysql
    restart: unless-stopped

    networks:
      - voxblog-network
    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-h", "localhost"]
      interval: 10s
      timeout: 5s
      retries: 5

  api:
    build:
      context: .
      dockerfile: docker/api.Dockerfile
    container_name: voxblog-api
    restart: unless-stopped
    ports:

```

## Step 3: Gitea Actions Workflow

```yaml
# .gitea/workflows/deploy.yml
name: Deploy to Production

on:
  push:
    branches:
      - main

jobs:
  deploy:
    runs-on: ubuntu-latest
    env:
      COMPOSE_PROJECT_NAME: voxblog
      INFISICAL_TOKEN: ${{ secrets.INFISICAL_TOKEN }}
      INFISICAL_SITE_URL: ${{ secrets.INFISICAL_SITE_URL }}
      INFISICAL_CLI_IMAGE: infisical/cli:latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Create placeholder .env
        run: touch .env

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v2

      - name: Load secrets from Infisical
        shell: bash
        run: |
          set -euo pipefail

          if [ -z "${INFISICAL_TOKEN}" ]; then
            echo "INFISICAL_TOKEN is not configured"
            exit 1
          fi

          CLI_IMAGE="${INFISICAL_CLI_IMAGE:-infisical/cli:latest}"
          docker pull "$CLI_IMAGE" >/dev/null

          tmp_file=$(mktemp)
          if [ -n "${INFISICAL_API_URL:-}" ]; then
            docker run --rm \
              -e INFISICAL_TOKEN="$INFISICAL_TOKEN" \
              ${INFISICAL_SITE_URL:+-e INFISICAL_SITE_URL="$INFISICAL_SITE_URL"} \
              -e INFISICAL_API_URL="$INFISICAL_API_URL" \
              "$CLI_IMAGE" export --format=dotenv > "$tmp_file"
          elif [ -n "${INFISICAL_SITE_URL:-}" ]; then
            api_url="${INFISICAL_SITE_URL%/}/api"
            docker run --rm \
              -e INFISICAL_TOKEN="$INFISICAL_TOKEN" \
              -e INFISICAL_SITE_URL="$INFISICAL_SITE_URL" \
              -e INFISICAL_API_URL="$api_url" \
              "$CLI_IMAGE" export --format=dotenv > "$tmp_file"
          else
            docker run --rm \
              -e INFISICAL_TOKEN="$INFISICAL_TOKEN" \
              "$CLI_IMAGE" export --format=dotenv > "$tmp_file"
          fi

          cp "$tmp_file" .env

          while IFS= read -r line || [ -n "$line" ]; do
            if [ -z "$line" ] || [[ "$line" == \#* ]]; then
              continue
            fi
            key="${line%%=*}"
            value="${line#*=}"
            echo "::add-mask::$value"
            printf '%s=%s\n' "$key" "$value" >> "$GITHUB_ENV"
          done < "$tmp_file"

          rm -f "$tmp_file"

      - name: Build and deploy
        run: |
          docker-compose down
          docker-compose build --no-cache
          docker-compose up -d

      - name: Run database migrations
        run: |
          docker-compose exec -T api pnpm run drizzle:migrate

      - name: Health check
        run: |
          sleep 10
          curl -f http://localhost:3301/api/health || exit 1
          curl -f http://localhost:3300 || exit 1

      - name: Clean up old images
        run: |
          docker image prune -af --filter "until=24h"
```

## Step 4: Deployment Script (Alternative to Gitea Actions)

If Gitea Actions is not available, you can still trigger deployments by SSH, cron, or a webhook that calls `deploy.sh`. The script now:

- Prefers `INFISICAL_TOKEN` and (optionally) `INFISICAL_SITE_URL` to pull secrets from Infisical via the official CLI container.
- Falls back to a local `.env` file only when no token is exported (for development/testing).
- Runs the same build → up → migrate → health-check flow afterwards.

Before running it manually or from a webhook, export the token:

```bash
export INFISICAL_TOKEN=st.your_service_token
export INFISICAL_SITE_URL=https://secrets.yourdomain.com  # optional
./deploy.sh
```

Everything else inside the script remains unchanged; see [deploy.sh](deploy.sh) for details.

## Step 5: Gitea Webhook Setup

### Option A: Using Gitea Actions (Recommended)

1. **Install Gitea Runner on your VPS:**
```bash
# Download Gitea Runner
wget https://dl.gitea.com/act_runner/latest/act_runner-latest-linux-amd64
chmod +x act_runner-latest-linux-amd64
sudo mv act_runner-latest-linux-amd64 /usr/local/bin/act_runner

# Register runner
act_runner register --instance https://your-gitea-url --token YOUR_RUNNER_TOKEN

# Run as service
sudo tee /etc/systemd/system/gitea-runner.service > /dev/null <<EOF
[Unit]
Description=Gitea Actions Runner
After=network.target

[Service]
Type=simple
User=git
WorkingDirectory=/home/git
ExecStart=/usr/local/bin/act_runner daemon
Restart=always

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable gitea-runner
sudo systemctl start gitea-runner
```

2. **Add secrets in Gitea:**
   - Go to your repository → Settings → Secrets
   - Add all environment variables as secrets

### Option B: Using Webhook + Script

1. **Create webhook endpoint:**
```bash
# Install webhook listener
sudo apt-get install webhook

# Create webhook config
sudo tee /etc/webhook.conf > /dev/null <<EOF
[
  {
    "id": "voxblog-deploy",
    "execute-command": "/path/to/voxblog/deploy.sh",
    "command-working-directory": "/path/to/voxblog",
    "response-message": "Deployment started",
    "trigger-rule": {
      "match": {
        "type": "payload-hash-sha256",
        "secret": "YOUR_WEBHOOK_SECRET",
        "parameter": {
          "source": "header",
          "name": "X-Gitea-Signature"
        }
      }
    }
  }
]
EOF

# Run webhook as service
sudo tee /etc/systemd/system/webhook.service > /dev/null <<EOF
[Unit]
Description=Webhook Service
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/webhook -hooks /etc/webhook.conf -verbose
Restart=always

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable webhook
sudo systemctl start webhook
```

2. **Configure Gitea webhook:**
   - Repository → Settings → Webhooks → Add Webhook
   - URL: `http://your-vps:9000/hooks/voxblog-deploy`
   - Secret: `YOUR_WEBHOOK_SECRET`
   - Trigger: Push events on main branch

## Step 6: Reverse Proxy (Nginx)

```nginx
# /etc/nginx/sites-available/voxblog
server {
    listen 80;
    server_name voxblog.yourdomain.com;

    # Redirect to HTTPS
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name voxblog.yourdomain.com;

    ssl_certificate /etc/letsencrypt/live/voxblog.yourdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/voxblog.yourdomain.com/privkey.pem;

    # Admin frontend
    location / {
        proxy_pass http://localhost:3300;
        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;
    }

    # API backend
    location /api {
        proxy_pass http://localhost:3301;
        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;
        
        # Increase timeout for AI streaming
        proxy_read_timeout 600s;
        proxy_send_timeout 600s;
    }
}
```

Enable site:
```bash
sudo ln -s /etc/nginx/sites-available/voxblog /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx
```

## Step 7: SSL Certificate

```bash
# Install certbot
sudo apt-get install certbot python3-certbot-nginx

# Get certificate
sudo certbot --nginx -d voxblog.yourdomain.com

# Auto-renewal is set up automatically
```

## Step 8: Environment Variables

Provision secrets in Infisical instead of maintaining a long-lived `.env` on disk:

1. Follow [INFISICAL_SETUP.md](INFISICAL_SETUP.md) to boot Infisical (already live at `https://secrets.pusula.blog`) and add VoxBlog secrets.
2. Create a production-scoped service token (scoped to the secret path you created).
3. Store the token securely; you'll export it whenever you deploy.

## Step 9: Initial Deployment

```bash
# Clone repository
cd /var/www  # or your preferred location
git clone https://your-gitea-url/your-username/voxblog.git
cd voxblog

# (Optional) Prepare local .env for development only
# cp .env.example .env && nano .env

# Export Infisical token for production deployment
export INFISICAL_TOKEN=st.your_service_token
export INFISICAL_SITE_URL=https://secrets.pusula.blog

# Initial deployment
./deploy.sh
```

## Step 10: Monitoring & Logs

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

# View specific service
docker-compose logs -f api
docker-compose logs -f admin

# Check status
docker-compose ps

# Restart services
docker-compose restart api
docker-compose restart admin
```

## Deployment Workflow

```
Developer pushes to main
        ↓
Gitea detects push
        ↓
Triggers Gitea Actions / Webhook
        ↓
Runs deploy.sh or workflow
        ↓
    1. Pull latest code
    2. Build Docker images
    3. Stop old containers
    4. Start new containers
    5. Run migrations
    6. Health check
    7. Clean up
        ↓
Deployment complete! ✅
```

## Rollback Strategy

```bash
# View recent images
docker images | grep voxblog

# Rollback to previous version
docker tag voxblog-api:latest voxblog-api:backup
docker tag voxblog-api:previous voxblog-api:latest
docker-compose up -d

# Or use git
git log --oneline
git checkout <previous-commit-hash>
./deploy.sh
```

## Best Practices

1. **Always test locally first:**
   ```bash
   docker-compose up --build
   ```

2. **Use health checks** in docker-compose.yml

3. **Backup database regularly:**
   ```bash
   docker-compose exec mysql mysqldump -u voxblog -p voxblog > backup.sql
   ```

4. **Monitor disk space:**
   ```bash
   docker system df
   docker system prune -a
   ```

5. **Use secrets management** - keep secrets in Infisical, never commit `.env`

6. **Set up monitoring** (optional):
   - Portainer for Docker management
   - Grafana + Prometheus for metrics
   - Uptime Kuma for uptime monitoring

## Troubleshooting

### Container won't start
```bash
docker-compose logs api
docker-compose exec api sh  # Debug inside container
```

### Database connection issues
```bash
docker-compose exec mysql mysql -u voxblog -p
# Check if database exists
SHOW DATABASES;
```

### Port already in use
```bash
sudo lsof -i :3301
sudo kill -9 <PID>
```

### Out of disk space
```bash
docker system prune -a --volumes
```

## Security Checklist

- [ ] Infisical secrets configured with strong values
- [ ] Enable firewall (ufw)
- [ ] Keep Docker updated
- [ ] Use SSL/TLS (HTTPS)
- [ ] Limit SSH access
- [ ] Regular backups
- [ ] Monitor logs for suspicious activity
- [ ] Use Docker secrets for sensitive data (advanced)

## Next Steps

1. Create all Docker files
2. Set up Gitea Runner or webhook
3. Configure environment variables
4. Test deployment locally
5. Deploy to production
6. Set up monitoring
7. Configure backups
