Push to Docker Hub Registry Lab
Tag and push TaskFlow Docker images to Docker Hub. Learn container registry concepts, image naming strategies, and prepare images for Kubernetes deployment in Week 8.
Lab Overview
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
