To avoid interactive prompts during the Docker image build process, you can set the DEBIAN_FRONTEND ~~environment variable~~ argument to "noninteractive." This prevents Debian-based package management tools, such as APT, from prompting for user input.

Example: Interactive Prompt during APT Package Installation

Suppose your Docker image needs the libglib2 package:

GLib is a library containing many useful C routines for things such as trees, hashes, lists, and strings. It is a useful general-purpose C library used by projects such as GTK+, GIMP, and GNOME.

Without the noninteractive mode set you will be prompted like this:

	#!/bin/bash

	echo "Executing post-install script"

	# Third party software dependencies
	dnf update -y
	dnf install git -y
	dnf install docker -y

	# Start Docker
