Learn Docker: A Beginner-Friendly Guide with Linux Fundamentals

What is Docker?

Docker is a powerful and highly sought-after tool for modern software development and deployment. However, getting started with Docker can be challenging, often requiring knowledge of Linux and navigating complex platform dependencies. Many learners find traditional Docker resources overwhelming due to the extensive prerequisite knowledge they assume.

This course takes a different approach. We'll start with the essential Linux basics needed to confidently use Docker. We'll focus on the core concepts, streamlining your learning journey.

Hands-on Learning with VirtualBox

To make learning easy and risk-free, we utilize VirtualBox, a popular virtualization tool, to create a Linux environment. Experiment with Docker without worrying about damaging your host system. We'll guide you through:

• Installing VirtualBox
• Installing CentOS (a popular Linux distribution) within VirtualBox
• Installing Docker on CentOS

Docker Toolbox for Windows & macOS

Many Docker resources focus on Linux, Windows 10 Professional, or the latest macOS, leaving those with limited access to these environments at a disadvantage. This course uses Docker Toolbox, which works seamlessly on Windows 10 Home and older macOS versions, making it accessible to a wider audience.

Practice problems are included to reinforce your understanding and solidify your skills.

This course is perfect for:

• Beginners interested in learning Docker.
• Developers needing Docker for their projects.
• Those who have struggled with Docker due to a lack of Linux knowledge.
• Junior programmers and developers (1-3 years experience).
• Testers looking to integrate Docker into their workflows.
• Infrastructure engineers wanting to understand Docker's role in modern deployments.
• Web app and cloud service developers seeking to containerize their applications.
• Researchers exploring Docker for AI and other development environments.
• Data scientists building data analysis infrastructure with Docker.
• IT managers preparing for employee training on containerization.

We'll guide you from the fundamentals, starting with the "penguin" of Linux and progressing towards the "whale" that is Docker!

Course Content

• Video Lectures: Clear and concise explanations of key concepts.
• Sample Code: Practical examples to illustrate Docker usage.
• Problem Sets & Solutions: Test your knowledge and reinforce learning.

Environment: We'll use CentOS 7 within VirtualBox for the initial Linux and Docker introductions. We'll also utilize Docker Toolbox (compatible with Windows and macOS) for Docker-related tasks, including editing files like Dockerfiles using Visual Studio Code (free and available for Windows, macOS, and Linux). The course primarily uses Windows for explanations, but the concepts apply to macOS and Linux. Adapt the instructions to your specific environment.

Prerequisites

• Basic PC operation skills.
• Fundamental understanding of software development.
• Basic knowledge of LAMP (Linux, Apache, MySQL, PHP) – understanding web application architecture.
• Basic networking knowledge: IP addresses, ports, and the OSI model.

Future Releases

We're continuously expanding this course! Upcoming topics include:

• Docker Compose for multi-container applications.
• Practical examples for various development scenarios.
• Docker Hub and automated builds.
• Integration with cloud environments.
• Kubernetes for orchestration.
