Docker Foundations

Building Modern Containerized Applications in 2 days

Introduction

Why this course

Practical Containerization Skills for Modern Developers and IT Professionals

Docker has transformed the way modern applications are built, tested, deployed, and maintained. As organizations increasingly adopt cloud-native architectures, DevOps practices, microservices, and scalable deployment pipelines, containerization has become a core operational requirement rather than a niche engineering skill. Docker provides a lightweight and highly portable platform that enables developers and infrastructure teams to package applications consistently across development, testing, staging, and production environments.

This two-day introductory course is designed to provide participants with a strong practical foundation in Docker technologies, container concepts, and real-world deployment workflows. The training focuses on hands-on operational knowledge aligned with current industry practices, including container image management, Docker networking, storage, Docker Compose, container security considerations, and integration into modern DevOps workflows. Current enterprise trends such as cloud-native development, container security hardening, remote development environments, and Kubernetes integration concepts are also incorporated to ensure relevance to today’s infrastructure landscape.

The course is delivered by an instructor with over 30 years of industry experience who emphasizes practical, production-oriented knowledge and real operational scenarios instead of purely academic theory.
