Free online courseDocker Containers and Kubernetes Fundamentals

Course Description

Modern software development increasingly depends on containerization and orchestration to deliver applications reliably, quickly, and at scale. This course gives you a practical foundation in Docker and Kubernetes so you can move from running code on your laptop to deploying services in repeatable, production-style environments. If you want skills that translate directly to DevOps, platform engineering, cloud development, or backend roles, you will gain a clear understanding of how containers fit into today’s delivery pipelines and why Kubernetes has become a standard for managing them.

You will learn how Docker packages applications and their dependencies into isolated containers that behave consistently across machines. From there, you will work with the workflows developers use every day: building images, running services, and making applications easier to manage over time. Special attention is given to multi-container setups and why a Compose file becomes essential when an application needs supporting components such as databases, caches, or message queues. You will also see how persistent data is handled in containerized environments and why volumes are central to safe, repeatable storage.

Once you are comfortable with containers, you will shift to Kubernetes fundamentals and the ideas behind orchestrating workloads. You will understand how Kubernetes groups containers into deployable units, how it helps keep applications running, and how it supports scaling and reliability goals. The course is hands-on, designed to help you practice the concepts rather than memorize definitions, so you finish with the confidence to read real-world configurations, troubleshoot common issues, and communicate effectively with engineering teams.

By the end, you should be able to explain the purpose of Docker Compose, when to use volumes, and how Kubernetes organizes and deploys containerized applications. Whether you are building projects, preparing for an interview, or trying to modernize your development workflow, this course provides a solid, practical starting point you can build on immediately.
