- Production Deployment: Deploy Dockerized applications in production environments
How to Learn Docker with This Guide
This guide is structured to make learning Docker an engaging and hands-on experience. Each chapter builds upon practical exercises, allowing you to apply Docker concepts step by step. Below is an overview of the tools and resources designed to enhance your learning journey.
This Guide
This guide provides clear, hands-on explanations of essential Docker concepts, making it ideal for both beginners and those looking to deepen their knowledge. Each key topic includes real-world case studies with step-by-step commands and code snippets. You can immediately test them and see the results in your local environment.
VS Code
For an optimal coding experience, this guide recommends Visual Studio Code (VS Code), a powerful and user-friendly text editor. If you don’t already have a preferred editor, VS Code is an excellent choice for working with Dockerfiles, YAML configurations, and containerized applications.
GitHub Repository
In Chapter 6, you'll work on deploying an application in a production environment. To help you follow along, we've prepared a GitHub repository containing project files. You can clone the repository to your local machine and test the deployment process step by step.
Docker Desktop and Docker Engine
Since Docker is the core focus of this guide, you’ll need to install Docker Desktop on your local machine and Docker Engine on a server for practice. In Chapter 2, we provide a detailed installation guide to help you set up your Docker environment. Later, in Chapter 6, you'll learn how to configure Docker Engine for real-world server deployments.
Free Downloadable Learning Resources
To help you practice effectively, we’ve prepared free downloadable resources:
- Project files for case studies: Easily test and experiment with Docker features on your local environment.
- PDF version of Chapters 1 and 2: Access key concepts anytime, anywhere for quick reference.
You can download these resources from the download page.
