import { Callout } from 'fumadocs-ui/components/callout'

## Schnellstart

```bash
# Clone and start
git clone https://github.com/simstudioai/sim.git && cd sim
docker compose -f docker-compose.prod.yml up -d
```

Öffnen Sie [http://localhost:3000](http://localhost:3000)

## Produktionseinrichtung

### 1. Umgebung konfigurieren

```bash
# Generate secrets
cat > .env << EOF
DATABASE_URL=postgresql://postgres:postgres@db:5432/simstudio
BETTER_AUTH_SECRET=$(openssl rand -hex 32)
ENCRYPTION_KEY=$(openssl rand -hex 32)
INTERNAL_API_SECRET=$(openssl rand -hex 32)
NEXT_PUBLIC_APP_URL=https://sim.yourdomain.com
BETTER_AUTH_URL=https://sim.yourdomain.com
NEXT_PUBLIC_SOCKET_URL=https://sim.yourdomain.com
EOF
```

### 2. Dienste starten

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

### 3. SSL einrichten

<Tabs items={['Caddy (Empfohlen)', 'Nginx + Certbot']}>
  <Tab value="Caddy (Empfohlen)">
Caddy verwaltet SSL-Zertifikate automatisch.

```bash
# Install Caddy
sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update && sudo apt install caddy
```

Erstellen Sie `/etc/caddy/Caddyfile`:

```
sim.yourdomain.com {
    reverse_proxy localhost:3000

    handle /socket.io/* {
        reverse_proxy localhost:3002
    }
}
```

```bash
sudo systemctl restart caddy
```

  </Tab>
  <Tab value="Nginx + Certbot">

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

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

    location / {
        proxy_pass http://127.0.0.1:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    location /socket.io/ {
        proxy_pass http://127.0.0.1:3002;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

# Enable and get certificate
sudo ln -s /etc/nginx/sites-available/sim /etc/nginx/sites-enabled/
sudo certbot --nginx -d sim.yourdomain.com
```

  </Tab>
</Tabs>

## Ollama

```bash
# With GPU
docker compose -f docker-compose.ollama.yml --profile gpu --profile setup up -d

# CPU only
docker compose -f docker-compose.ollama.yml --profile cpu --profile setup up -d
```

Zusätzliche Modelle herunterladen:

```bash
docker compose -f docker-compose.ollama.yml exec ollama ollama pull llama3.2
```

### Externes Ollama

Wenn Ollama auf Ihrem Host-Rechner läuft (nicht in Docker):

```bash
# macOS/Windows
OLLAMA_URL=http://host.docker.internal:11434 docker compose -f docker-compose.prod.yml up -d

# Linux - use your host IP
OLLAMA_URL=http://192.168.1.100:11434 docker compose -f docker-compose.prod.yml up -d
```

<Callout type="warning">
  Innerhalb von Docker bezieht sich `localhost` auf den Container, nicht auf Ihren Host. Verwenden Sie `host.docker.internal` oder die IP-Adresse Ihres Hosts.
</Callout>

## Befehle

```bash
# View logs
docker compose -f docker-compose.prod.yml logs -f simstudio

# Stop
docker compose -f docker-compose.prod.yml down

# Update
docker compose -f docker-compose.prod.yml pull && docker compose -f docker-compose.prod.yml up -d

# Backup database
docker compose -f docker-compose.prod.yml exec db pg_dump -U postgres simstudio > backup.sql
```
