Push to Docker Hub Registry Lab

🛠 Lab from the Platform Engineering Bootcamp. Used in Week 7. Bootcamp landing page: https://academy.tekanaid.com/bootcamps/platform-engineering-bootcamp Parent course(s):

• Week 7: Docker Fundamentals (slug: docker-fundamentals)

Learn how to publish and distribute container images using Docker Hub registry. Lab setup builds the real TaskFlow backend and frontend images from the same production Dockerfiles you wrote and ran in the two previous Week 7 labs. You'll authenticate the Docker CLI with your own real Docker Hub account (a free account works), tag those images with proper versioning conventions, push them for real, and pull them back down to verify the round-trip.

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

Note: You'll need (or will create) a free Docker Hub account for this lab, this is the first lab in the bootcamp that authenticates against Docker Hub instead of GitHub.

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
