# Pre-built Docker Images for MCP Gateway Registry

When using the `--prebuilt` option with `build_and_run.sh`, the following pre-built Docker images are pulled from Docker Hub. These images are published to the `mcpgateway` organization on Docker Hub.

## Manual Download Commands

To manually pull these images for Kubernetes deployment or offline use:

```bash
# MCP Gateway images from Docker Hub
docker pull mcpgateway/registry:latest
docker pull mcpgateway/auth-server:latest
docker pull mcpgateway/metrics-service:latest
docker pull mcpgateway/currenttime-server:latest
docker pull mcpgateway/fininfo-server:latest
docker pull mcpgateway/mcpgw-server:latest
docker pull mcpgateway/realserverfaketools-server:latest

# External images
docker pull alpine:latest
docker pull prom/prometheus:latest
docker pull grafana/grafana:latest
docker pull postgres:16-alpine
docker pull quay.io/keycloak/keycloak:25.0
docker pull mongo:8.2
```

## HTTPS Configuration

By default, pre-built images run on HTTP (port 80) only. To enable HTTPS (port 443):

### Option 1: Let's Encrypt Certificates

```bash
# Install certbot
sudo apt-get update && sudo apt-get install -y certbot

# Obtain certificate (requires domain and port 80)
sudo certbot certonly --standalone -d your-domain.com

# Certificate files will be at:
# - /etc/letsencrypt/live/your-domain/fullchain.pem
# - /etc/letsencrypt/live/your-domain/privkey.pem
```

### Option 2: Commercial CA Certificates

Purchase SSL certificates from a trusted Certificate Authority.

### Copy Certificates to Expected Location

```bash
# Create the ssl directory structure
mkdir -p ${HOME}/mcp-gateway/ssl/certs
mkdir -p ${HOME}/mcp-gateway/ssl/private

# Copy your certificate files
# Replace paths below with your actual certificate locations
cp /etc/letsencrypt/live/your-domain/fullchain.pem ${HOME}/mcp-gateway/ssl/certs/fullchain.pem
cp /etc/letsencrypt/live/your-domain/privkey.pem ${HOME}/mcp-gateway/ssl/private/privkey.pem

# Set proper permissions
chmod 644 ${HOME}/mcp-gateway/ssl/certs/fullchain.pem
chmod 600 ${HOME}/mcp-gateway/ssl/private/privkey.pem
```

**Note**: If SSL certificates are not present at `${HOME}/mcp-gateway/ssl/certs/fullchain.pem` and `${HOME}/mcp-gateway/ssl/private/privkey.pem`, the MCP Gateway will automatically run in HTTP-only mode.

Then restart:

```bash
./build_and_run.sh --prebuilt
```

The registry container will detect the certificates and enable HTTPS automatically. Check logs:

```bash
docker compose logs registry | grep -i ssl
# Expected: "SSL certificates found - HTTPS enabled"
```
