Docker Program (Beginner)

Docker has become one of the most essential tools in modern software development, enabling developers to build, ship, and run applications inside lightweight, portable containers. Whether you are a developer, system administrator, or DevOps enthusiast, learning Docker will give you the skills to streamline workflows, improve application portability, and deploy software faster. This 30-day step-by-step roadmap is designed to take you from a complete beginner to an intermediate-level Docker practitioner. Each day introduces you to a focused topic, starting with the fundamentals of containerization and gradually moving towards multi-container applications, orchestration, security, and integration with CI/CD pipelines. You will begin by understanding Docker architecture, images, and containers, then move on to building custom images, managing data, networking, and using Docker Compose. As you progress, you will explore resource management, security practices, orchestration with Docker Swarm, and even compare Docker with Kubernetes. The program ends with a final hands-on project, where you will build and deploy a real-world multi-container application. By following this roadmap, you will gain: A solid foundation in Docker concepts and commands Hands-on experience with building and managing containers Skills to work with Docker Compose, networking, and volumes Knowledge of security, resource optimization, and orchestration Confidence to deploy applications in real-world scenarios Whether your goal is to enhance your development workflow, prepare for DevOps roles, or deploy scalable microservices, this 30-day roadmap will guide you step-by-step toward Docker mastery.
