-# GSIO-Net Docker Compose Configuration
-# 
-# This file defines a network of GSIO-Net nodes that can communicate with each other.
-# It creates three nodes, each exposing the API on a different host port:
-#   - node1: http://localhost:3001
-#   - node2: http://localhost:3002
-#   - node3: http://localhost:3003
-#
-# Usage:
-#   - Start the network: docker-compose up -d
-#   - View logs: docker-compose logs -f
-#   - Stop the network: docker-compose down
-#   - Stop and remove volumes: docker-compose down -v
