Docker for beginners: Build and Dockerize a basic nodejs app

In today’s fast-paced software development landscape, containerization has become a critical skill for developers, IT professionals, and organizations aiming to streamline their deployment processes. Docker, the leading platform for containerization, allows developers to package applications into containers—lightweight, portable, and self-sufficient units that can run consistently across any environment. If you’re new to Docker and eager to learn how to leverage it in your projects, this course is designed just for you.

Docker for Beginners: Build and Dockerize a Basic Node.js App is a  hands-on course tailored to those who are new to Docker and containerization. Whether you’re a beginner developer, an IT operations professional, or a tech enthusiast, this course will equip you with the foundational skills needed to integrate Docker into your development workflow. By the end of this course, you’ll be able to create, deploy, and manage Docker containers for a Node.js application, making your development process more efficient, scalable, and consistent across different environments.

What You’ll Learn:

Introduction and Setup

We start with the basics, ensuring you understand what Docker is and why it’s so powerful. You’ll learn about Docker’s core concepts, its use cases, and how it revolutionizes software deployment. We’ll guide you through the installation and setup of Docker Desktop on your local machine, making sure you’re ready to dive into the world of containerization. You’ll also explore the Docker Desktop interface, understand the Docker architecture, and get acquainted with Docker Hub, the central repository for Docker images.

Docker Essentials

In this module, you’ll gain hands-on experience by running your first Docker container. You’ll learn how to create, run, and manage Docker images—essential skills for any developer working with Docker. We’ll walk you through setting up a basic Node.js application, where you’ll install Node.js, Express, and essential tools like Visual Studio Code and Nodemon. By the end of this section, you’ll have a fully functional Node.js application ready for containerization.

Dockerizing a Basic Node.js App

The heart of this course lies in containerizing your Node.js application. You’ll start by creating a Dockerfile, which defines the environment in which your application will run. We’ll teach you how to optimize your Docker builds using a dockerignore file, and guide you through the process of building and running your Docker image. You’ll also learn how to shut down and manage Docker containers, ensuring you have full control over your Dockerized applications.
