Publishing Container Images to Docker Hub

Packaging your application is only the first step; to deploy or share it, you need to distribute your container images safely and efficiently. Docker Hub is the central registry that makes this distribution possible, serving as the bridge between your local development environment and the cloud. This text-based course guides you through the entire lifecycle of managing and publishing container images. You will start with the fundamental concepts of registries and repositories, move on to building and tagging images correctly, and finish by pushing your work to a public or private registry. What you'll learn: Understand the core concepts of container registries, repositories, and image layers; Build and tag Docker images using industry-standard naming conventions; Create and configure repositories on Docker Hub for public or private access; Authenticate safely with Docker Hub using personal access tokens instead of passwords; Push local images to the registry and manage different versions using tags; Apply basic security practices, including image scanning and minimizing layer sizes; Explore multi-platform builds to ensure your images run on different CPU architectures. The course begins with essential terminology and setup, guiding you step-by-step through local image preparation, registry authentication, and successful publishing. This course is designed for beginners to containerization and DevOps workflows; no prior experience with cloud registries is required, though basic familiarity with the command line is helpful.
