Course Description

Docker and Containerization training course Overview

This one-day beginner-level Docker course offers an introduction to Docker and containerization technologies, providing participants with the foundational skills to leverage Docker for developing, deploying, and managing applications. The course covers key concepts such as the benefits of containerization, Docker’s architecture, and how it differs from virtual machines.

Participants will engage in hands-on exercises, installing Docker on various operating systems (Windows, macOS, Linux), running their first container, and learning essential Docker commands for managing containers. The course also covers working with Docker images, building custom Docker images using Dockerfiles, and optimizing images for better performance.

By the end of this Docker course, participants will have a solid understanding of Docker containers, how to manage them, and how to use Docker to enhance development workflows, DevOps practices, and system administration tasks.

Course Outline
