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)

🟡 Beta bootcamp lab. Hands-on instructions, check scripts, and solve scripts are in place. Lab is part of the running TaskFlow project that grows across all 21 weeks of the bootcamp.

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
