- `docker-compose -f docker-compose.yml up --build`
- Configure the project for user specs, modify the `docker-compose.yml` file for the following parameters:
```bash

To build the Docker image and start the container, run:
```bash
docker-compose -f docker-compose.yml up --build
```
This will build the Docker image and start the container with the XBee network and the required setup.
#### 4. Health Check and Container Management
#### 5. Health Check and Container Management
The container includes a health check that pings the XBee network interface to ensure it is functioning properly. \
The container is configured to restart automatically if the health check fails.
#### 5. Troubleshooting
#### 6. Troubleshooting
Ensure the XBee devices are connected to the correct serial ports.\
Verify the network interfaces using ip a inside the container.\

# This script sets up the environment for running a Docker Compose configuration with XBee networks.
# It accepts optional --index=<int>, --subnet=<subnet>, --serial-speed=<speed>, --port=<port>, and --interface-type=<type> arguments
# to specify the XBEE_INDEX, BASE_SUBNET, XBEE_BAUDRATE, XBEE_PORT, and XBEE_INTERFACE_TYPE values.
# If no index is provided, it defaults to 1. If no subnet is provided, it defaults to 192.168.1.

# If no serial-speed is provided, it defaults to 230400. If no port is provided, it defaults to /dev/ttyUSB0.
