# Ръководство за Внедряване (Deployment)

## Docker

За пълно ръководство за Docker deployment вижте [Docker Guide](docker.md).

### Бърз старт

```bash
docker build -t baradb:latest .
docker compose up -d
```

### Docker Compose файлове

| Файл | Назначение |
|------|-----------|
| `docker-compose.yml` | Development |
| `docker-compose.prod.yml` | Production |
| `docker-compose.override.yml` | Dev override (автоматично) |
| `docker-compose.test.yml` | Тестова среда |

### Production

```bash
docker compose -f docker-compose.prod.yml up -d
```

### Docker Swarm

```bash
docker stack deploy -c docker-compose.prod.yml baradb
```

## systemd Услуга

Създайте `/etc/systemd/system/baradb.service`:

```ini
[Unit]
Description=BaraDB Multimodal Database
After=network.target

[Service]
Type=simple
User=baradb
Group=baradb
WorkingDirectory=/var/lib/baradb
ExecStart=/usr/local/bin/baradadb
Restart=always
RestartSec=5

Environment=BARADB_PORT=9472
Environment=BARADB_HTTP_PORT=9470
Environment=BARADB_DATA_DIR=/var/lib/baradb/data
Environment=BARADB_LOG_LEVEL=info

# Подсилване на сигурността
NoNewPrivileges=true
ProtectSystem=strict
ProtectHome=true
ReadWritePaths=/var/lib/baradb/data
ProtectKernelTunables=true
ProtectKernelModules=true
ProtectControlGroups=true

[Install]
WantedBy=multi-user.target
```

Активиране и стартиране:

```bash
sudo useradd -r -s /bin/false baradb
sudo mkdir -p /var/lib/baradb/data
sudo chown -R baradb:baradb /var/lib/baradb
sudo cp build/baradadb /usr/local/bin/
sudo systemctl daemon-reload
sudo systemctl enable --now baradb
```

## Kubernetes

### StatefulSet

```yaml

## Reverse Proxy (nginx)

```nginx
upstream baradb_http {
    server 127.0.0.1:9470;
}

upstream baradb_ws {
    server 127.0.0.1:9471;
}

server {
    listen 80;
    server_name db.example.com;
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name db.example.com;

    ssl_certificate /etc/letsencrypt/live/db.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/db.example.com/privkey.pem;

    location /api/ {
        proxy_pass http://baradb_http/;
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }

    location /ws/ {
        proxy_pass http://baradb_ws/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
```

## Висока Достъпност (High Availability)

### 3-Възел Raft Клъстер

```bash
# Възел 1
BARADB_RAFT_NODE_ID=node1 \
BARADB_RAFT_PEERS=node2:9001,node3:9001 \
./build/baradadb

# Възел 2
BARADB_RAFT_NODE_ID=node2 \
BARADB_RAFT_PEERS=node1:9001,node3:9001 \
./build/baradadb

# Възел 3
BARADB_RAFT_NODE_ID=node3 \
BARADB_RAFT_PEERS=node1:9001,node2:9001 \
./build/baradadb
```

## Облачно Внедряване

### AWS EC2

Препоръчителна инстанция: `m6i.2xlarge` (8 vCPU, 32 GB RAM)

```bash
# User data скрипт
#!/bin/bash
apt-get update
apt-get install -y nim
wget https://github.com/katehonz/barabaDB/releases/latest/download/baradadb-linux-amd64
chmod +x baradadb-linux-amd64
mv baradadb-linux-amd64 /usr/local/bin/baradadb

mkdir -p /data/baradb
cat > /etc/systemd/system/baradb.service << 'EOF'
[Unit]
Description=BaraDB
After=network.target
[Service]
ExecStart=/usr/local/bin/baradadb
Environment=BARADB_DATA_DIR=/data/baradb
Restart=always
[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload
systemctl enable --now baradb
```

### GCP Cloud Run (само HTTP)

```bash
gcloud run deploy baradb \
  --image gcr.io/PROJECT/baradb \
  --port 9470 \
  --memory 4Gi \
  --cpu 2 \
  --max-instances 10
```
