Developed a containerization CI/CD workflow for the pcottle/learnGitBranching repository, focusing on automating Docker image builds and publishing to GitHub Container Registry. Leveraging GitHub Actions, Shell scripting, and YAML, the workflow builds images for each commit, applies both commit-specific and latest tags, and streamlines repository prefix configuration. Iterative improvements across multiple commits enhanced permission hardening and simplified configuration, resulting in a secure and reproducible deployment process. This approach enables faster, traceable releases and strengthens the security posture for containerized environments, providing maintainers with a lean, automated pipeline that supports reliable, per-commit image publishing and improved operational transparency.
