Summary

This checkpoint completes the CI/CD phase of the DevSecOps Learning Lab by extending GitHub Actions into a deployment pipeline.

What was implemented

• Added automated testing with GitHub Actions.
• Built Docker images inside GitHub runners.
• Created and configured a Docker Hub account.
• Added secure authentication using GitHub Secrets.
• Automated Docker image tagging and publishing.
