# 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
