#!/bin/bash

# Usage:
# This script automates the setup and deployment of Nemesis environment using k3s,
# installs necessary tools like curl, iptables, Helm, and deploys the Nemesis platform.
# It supports providing an IP address as an argument or interactively during execution.
#
# Requirements:
# - A Linux-based system with apt package manager (Debian, Ubuntu, etc.)
# - sudo privileges for the executing user
#
# How to run:
# 1. Without an IP address (interactive mode): ./debian_k3s_setup.sh
# The script will prompt for an IP address or use the default 127.0.0.1.
# 2. With an IP address: ./debian_k3s_setup.sh <IP_Address>
# The script will use the provided IP address for the Nemesis platform.
#
# Steps performed by the script:
# 1. Checks and installs curl and iptables if they are not already installed.
# 2. Validates the provided IP address or prompts the user for one.
# 3. Installs k3s and configures the Kubernetes environment.
# 4. Installs Helm and uses it to install necessary dependencies and the Nemesis platform.
# 5. Sets up basic authentication for Nemesis and provides login information.
