The Complete Practical Docker Guide - Challenge: Create Files Handling Node App

The video tutorial covers handling signals like SIGINT in applications, demonstrating how to create a Node.js application that prompts for a file name and text, then creates a file with the given content. The tutorial includes a challenge to build this application using Node.js built-in modules or third-party packages. It also provides a demonstration of the application and instructions on running it using Docker. The video concludes with a summary of the task and a preview of the next steps.
