The Complete Practical Docker Guide - Add Handling of the SIGINT and SIGTERM Signals

This video tutorial covers the setup and execution of a Node.js application using Docker. It addresses the challenge of handling signals like SIGINT and SIGTERM in Node.js processes. The tutorial demonstrates how to modify the application to handle these signals using the process package, ensuring proper termination of the application. It includes testing the application to verify the implementation and concludes with a summary and next steps for learners.

What package is primarily used to create a web server in the Node.js application discussed?

• Hapi

• Meteor

• Koa

• Express

What is the main challenge discussed in handling signals for the Node.js application?

• Application not starting

• Application not responding to SIGINT

• Application not connecting to the database

• Application not logging errors

Which Node.js package is used to handle process signals like SIGINT?

• Signal

• Stream

• Process

• Events

What message is printed when the application handles a SIGINT signal?

• Application is being started

• Application is being debugged

• Application is being interrupted

• Application is being updated

What Docker command is used to send a SIGTERM signal to the Node.js process?

• docker start

• docker pause

• docker stop

• docker restart

Why is it important to handle SIGTERM signals in a Dockerized Node.js application?

• To improve application performance

• To enhance application scalability

• To ensure proper shutdown of the application

• To increase application security

What is the exit code used to indicate a successful termination of the process?

• 0

• 100

• 1

• 255
