To run the script:

wget -O manage-server.sh https://raw.githubusercontent.com/djurcola/UbuntuManagementScript/refs/heads/master/manage-server.sh
chmod +x manage-server.sh
sudo ./manage-server.sh


To extend the script:
#Create a new function:
# --- Action: Configure UFW Firewall ---
function configure_firewall() {
    echo -e "\n${GREEN}--- Configuring UFW Firewall ---${NC}"
    apt-get install -y ufw
    ufw default deny incoming
    ufw default allow outgoing
    ufw allow ssh
    ufw allow http
    ufw allow https
    # Use 'y' to proceed without interactive confirmation
    echo "y" | ufw enable
    ufw status verbose
    echo -e "${GREEN}--- UFW Firewall Configuration Complete ---${NC}"
}

# Add a new option to the main menu:
# Inside the main_menu function's echo block...
echo "4) Install Docker"
echo "5) Configure Firewall (UFW)" # <-- Add this line
echo "----------------------------------------"


# Add a new case in the case statement to call your new function:
# Inside the case statement in main_menu...
    4)
        install_docker
        ;;
    5) # <-- Add this new block
        configure_firewall
        ;;
    q|Q)


#(Optional) Add it to run_all_actions if you want it to be part of the "Run All" sequence:

function run_all_actions() {
    echo -e "\n${YELLOW}===== RUNNING ALL ACTIONS =====${NC}"
    update_system
    setup_unattended_upgrades
    install_docker
    configure_firewall # <-- Add this line
    echo -e "\n${YELLOW}===== ALL ACTIONS COMPLETED =====${NC}"
}
