🐳 Docker Compose Setup

1. Build and start all services:

   docker compose up --build -d

2. Check logs for all services:

   docker compose logs -f

3. Stop all services:

   docker compose down

4. (Optional) Rebuild without cache:

   docker compose build --no-cache

• Make sure you have your environment variables set in backend/.env and frontend/.env before building, use the .env.example files as templates.
• The frontend should be built locally (npm run build) and the output copied to backend/frontend/build if you are not building the frontend inside Docker.
• Run build_and_copy_frontend.sh to automate this process.
