# run-single.sh
#
# This script sets up the environment for running a Docker Compose configuration with XBee networks.
# It accepts optional --index=<int> and --subnet=<subnet> arguments to specify the XBEE_INDEX and BASE_SUBNET values.
# If no index is provided, it defaults to 1. If no subnet is provided, it defaults to 192.168.1.
#
# Usage:
#   ./run-single.sh                             # Runs with default index (1) and default subnet (192.168.1)
#   ./run-single.sh --index=2                   # Runs with index 2 and default subnet (192.168.1)
#   ./run-single.sh --subnet=192.168.50         # Runs with default index (1) and subnet 192.168.50
#   ./run-single.sh --index=3 --subnet=192.168.50 # Runs with index 3 and subnet 192.168.50
#
# IPs assigned:
#   BASE_SUBNET:                                    eg.: 192.168.1
#   DEFAULT_GATEWAY:    ${BASE_SUBNET}.1,           eg.: 192.168.1.1
#   DEFAULT_IPVLAN_IP:  ${BASE_SUBNET}.20           eg.: 192.168.1.20
#   DEFAULT_MACVLAN_IP: ${BASE_SUBNET}.30           eg.: 192.168.1.30
#   XBEE_NET_SRC_IP:    ${BASE_SUBNET}.20${index}   eg.: 192.168.1.201  (all Xbnets will be in the 200+ range)
