Docker Containerization Essentials

Docker Containerization Essentials is an introductory, hands-on course that teaches the core concepts and practical skills required to build, run, and manage containerized applications using Docker. The course focuses on how containerization enables consistent application deployment across development, testing, and production environments. Learners will gain experience creating Docker images, running and managing containers, using Dockerfiles, working with container registries, and understanding container networking and storage. By the end of the course, participants will have the foundational knowledge needed to containerize applications and prepare them for orchestration platforms such as Kubernetes.
