Push to Docker Hub Registry Lab

Learn how to publish and distribute container images using Docker Hub registry. You'll authenticate with a mock Docker Hub account, tag your TaskFlow images with proper versioning conventions, push them to a simulated registry, and pull them back to verify the process.

This lab prepares you for Kubernetes in Week 8, where you'll deploy these same images from a registry. You'll learn image naming best practices, semantic versioning strategies, and registry authentication patterns used in production environments.

Note: This lab uses a simulated Docker Hub environment to teach real-world registry workflows without requiring external accounts.

By the end of this lab, you'll understand:

• Docker Hub registry authentication from CLI
• Image naming conventions (username/repository:tag)
• Semantic versioning strategies (latest, v1.0.0, v1.0.1)
• Registry authentication and credential storage
• Image publication and distribution workflows
• Preparing images for Kubernetes deployment
