Manuel Bilbao developed and integrated a comprehensive CI/CD workflow for the lambdaclass/rex repository, focusing on automating Docker image build and publish processes. Leveraging GitHub Actions and YAML, he designed a pipeline that logs into the container registry, builds and pushes Docker images, and extracts image metadata. The workflow also generates artifact attestations, ensuring container image provenance and auditability. By automating these steps, Manuel eliminated manual deployment tasks and improved release reliability, addressing the need for reproducible and traceable deployments. His work demonstrated a strong grasp of CI/CD principles, Docker, and workflow automation, delivering a robust foundation for future releases.
