• Docker and Docker Compose
• Open ports 80 and 443 (if using HTTPS)

1. Clone the repository:

   git clone https://github.com/yourorg/opencex.git
   cd opencex

2. Run the setup script:

   chmod +x setup.sh
   ./setup.sh

If you prefer manual setup:

1. Create external network:

   docker network create caddy

2. Copy environment file:

   cp .env.example .env

3. For HTTP-only (development):

   • Leave DOMAIN=:80 in .env

4. For HTTPS with custom domain:

   • Set DOMAIN=yourdomain.com in .env
   • Ensure DNS points to your server

5. Start services:

   docker compose up -d

Issue: Caddy shows errors about certificates

• Solution: You're using an AWS EC2 hostname or IP address. Set DOMAIN=:80 for HTTP-only mode, or use a real domain name.

Issue: Services not accessible

• Check: docker ps - all containers should be "Up"
• Check: docker logs opencex-caddy-1 for errors
• Verify ports 80/443 are open in firewall/security groups
