Publishing Docker Images to Container Registries

Packaging your applications into container images is only half the battle; you must also know how to share and deploy them reliably. This text-based course guides you through the entire process of preparing and distributing Docker images using industry-standard registries. You will transition from building local containers to managing a secure, automated distribution pipeline. Through clear written explanations and practical command-line exercises, you will learn how to structure your images efficiently, manage authentication, and publish your work so it can be deployed anywhere. What you'll learn: - Understand core registry concepts, including public versus private repositories and OCI standards. - Build optimized images using multi-stage builds to minimize size and reduce security risks. - Tag images correctly using semantic versioning and best practices for environment-specific deployments. - Authenticate securely with registries like Docker Hub and GitHub Container Registry using access tokens. - Push and pull images safely while incorporating basic vulnerability scanning before publication. - Configure automated build and publish workflows for modern development pipelines. The course begins with foundational definitions of images, layers, and registries, then moves step-by-step through local builds, tagging strategies, authentication, and secure publishing. It is designed specifically for software developers, DevOps beginners, and system administrators who have a basic understanding of the command line but are new to container distribution.
