Docker for Beginners: Containerization Made Simple

Gain practical Docker skills for DevOps—learn containerization, image creation, and deployment fundamentals.

What you'll learn
- Understand the fundamentals of containerization — explain how containers differ from virtual machines and why modern systems use containers
- Build and run containers using Docker
- Author and optimize Dockerfiles
- Apply core container management skills
- Implement security and best practices
- Compare container technologies and platforms

Requirements
- No prior Docker experience required — this course starts from the absolute basics and builds up step-by-step.
- Basic computer literacy — ability to use a terminal/command prompt and install software on your system.
- Familiarity with software development concepts (optional but helpful), such as what an application or server is.
- A computer with Windows, macOS, or Linux capable of running Docker Desktop or Podman.
- A Docker Hub account — free to create, used for uploading and sharing container images.

Description
In today’s cloud-driven world, understanding containers is an essential skill for developers, DevOps engineers, and IT professionals who want to deliver software efficiently and consistently. This course teaches youDocker and containerization from the ground up, using simple explanations, practical examples, and hands-on labs designed to help you learn by doing.

You’ll begin by exploringwhy containers are neededand how they differ from traditional virtual machines in terms of speed, efficiency, scalability, and resource usage. From there, you’ll walk through installing Docker, running your first container, and pulling official images from Docker Hub. As you progress, you’ll learn how to write and customizeDockerfiles, build your own images, and understand each layer of the container stack in detail.

Through guided labs, you’ll practice creatingmulti-stage buildsfor optimization, and later applysecurity best practicessuch as running containers as non-root users, enforcing read-only file systems, and setting runtime limits for memory and CPU resources.

By the end of this course, you’ll confidently be able tobuild, run, optimize, and secure Docker containers—skills directly applicable to real-world DevOps pipelines, Kubernetes deployments, and modern cloud environments.

Join today and start mastering the essential skills that power today’s scalable, portable, and secure applications.

Who this course is for:
- Developers and software engineers who want to package and deploy their applications consistently across different environments.
- DevOps beginners and system administrators who are learning how to containerize applications and manage images in production.
- IT professionals and cloud practitioners preparing to work with Kubernetes, AWS ECS, or other container orchestration platforms.
- Students and self-learners interested in understanding modern infrastructure concepts like virtualization vs containerization.
- Educators or team leads who want to teach or demonstrate container fundamentals in a clear, hands-on way.
