Master Docker containerization from fundamentals to production deployment. Learn to build, run, and manage containers, create Dockerfiles, work with Docker Compose, and deploy multi-container applications. Essential DevOps skills for modern development workflows.
Docker Essentials for Developers is a free intermediate course that takes you from zero Docker knowledge to confidently running and managing containerized applications. Starting with the fundamentals of what containers are and how they differ from virtual machines, you work through Docker's core architecture, then move into hands-on practice: installing Docker, running your first container, and understanding the full container lifecycle. From there, the course covers Docker images, Docker Hub, and how to pull and manage images from public registries.
The second half dives into skills that matter in real development workflows. You will write Dockerfiles from scratch, apply multi-stage builds to keep images lean, manage persistent data with volumes and bind mounts, and configure networking so containers can communicate with each other and the outside world. Docker Compose gets its own dedicated module, walking you through the Compose file format and building multi-container applications in a way that mirrors real project setups. You also learn to handle environment variables and secrets safely, which matters for both development and production environments.
This course suits developers, students, and anyone moving into DevOps or cloud-adjacent roles who wants practical containerization skills. No prior Docker experience is needed, though familiarity with the command line will help. The final module covers real-world development workflows, debugging running containers, and where to go next. Finish all modules and pass the final exam to earn a free certificate of completion you can add to your LinkedIn profile or resume.
