Syllabus

Introduction

In this module, we will establish the foundation for the course by outlining the necessary prerequisites and key takeaways. We will also explore a hands-on Docker demonstration to provide a clear understanding of its capabilities and significance in modern development workflows.

Docker - Full Introduction: What is it? How it Works? And It's Importance

In this module, we will explore Docker from the ground up, covering its fundamental concepts, how it operates, and why it has become essential in modern development. We will also discuss its deployment benefits, examine Docker containers in detail, and compare Docker with traditional virtualization to understand its evolution. Finally, we will summarize the key takeaways to reinforce learning.

Setup Development Environment

In this module, we will walk through the complete setup of a development environment for working with Docker. We will guide you through installing Visual Studio Code, setting up the Docker Desktop application, and running it to ensure a smooth development workflow. By the end, you’ll have everything in place to start working with Docker efficiently.

Docker Fundamentals - Hands-on Deep Dive - HANDS-ON

In this module, we will dive into hands-on Docker fundamentals, starting with running basic containers and progressing to more advanced features like volume management, data persistence, and customization. We will explore real-world scenarios, such as mounting volumes, sharing data between containers, and hosting a website using NGINX. By the end of this section, you'll have a solid practical understanding of Docker's core functionalities.

[OPTIONAL] Linux Basics

In this module, we will cover fundamental Linux concepts, which are crucial for working within the Docker ecosystem. We will explore the Linux file system, introduce essential commands for navigation and file management, and reinforce these concepts with a summary. This optional section is ideal for learners new to Linux or those looking to refresh their knowledge before diving deeper into Docker.

[HANDS-ON] Dockerfile and Images - Publishing Your Own Images to Dockerhub

In this module, we will explore Dockerfiles and images, starting with the fundamentals of Dockerfile structure and directives. We will apply this knowledge by creating and dockerizing a simple RandomQuote web app, improving it with a web interface, and understanding the role of base images. Finally, we will cover the process of publishing Docker images to DockerHub, ensuring learners can share and distribute their containerized applications.

Docker Layers and Caching

In this module, we will dive into Docker layers and caching, focusing on how they impact image builds and performance. We will compare unoptimized and optimized Dockerfiles to highlight caching benefits and explore best practices for building lean and efficient Docker images. By the end, you’ll have a clear understanding of how to leverage Docker layers for faster and more effective containerization.

Docker Compose - Building a 2-Tier Web App & Dockerizing It
