Publishing Docker Images: Packaging and Pushing to Docker Hub

Creating containerized applications is only the first step; to deploy and share your work, you must know how to distribute your Docker images securely and efficiently. This text-based course guides you through the complete workflow of preparing, tagging, and uploading your local Docker images to Docker Hub, the world's leading container registry. What you will learn: 1. Understand foundational container registry concepts and how Docker Hub stores images. 2. Build and tag Docker images correctly using semantic versioning and best practices. 3. Authenticate securely with Docker Hub using Personal Access Tokens instead of raw passwords. 4. Push images to public and private repositories using the command-line interface. 5. Optimize image sizes before distribution using multi-stage build concepts. 6. Perform basic security scans on your images to identify vulnerabilities before publishing. You will start with core terminology and registry basics, then progress through step-by-step written explanations covering authentication, tagging strategies, and the push command. This course is designed for beginner developers, DevOps newcomers, and system administrators who have basic Docker familiarity but have never published their own images. Start reading today to confidently share your containerized applications with the world.
