Over a two-month period, Andrew Sinclair developed and modernized container images for go-httpbin in the app-sre/container-images repository, focusing on reproducibility, compliance, and automation. He introduced a Dockerfile using Red Hat Universal Base Image 9, configured go-httpbin as the entrypoint, and standardized build workflows to reduce environment drift. In July, Andrew optimized the Dockerfile with ARG-based versioning and a smaller base image, and implemented Tekton-based CI/CD pipelines for automated, multi-architecture builds. By leveraging Go, Docker, and Tekton, he improved build speed, release reliability, and compliance, enabling faster deployment cycles and more consistent, maintainable containerized services across environments.

July 2025 — Key container-image work focused on Go-httpbin modernization and automation. Delivered Dockerfile optimizations and CI/CD automation to improve build speed, reproducibility, and release cadence for the app-sre/container-images repo. No explicit major defects recorded in this period; efforts targeted quality, compliance, and operational efficiency. Key achievements: - Dockerfile modernization for go-httpbin: ARG-based versioning, smaller base image, streamlined install/copy steps, and Konflux-compatible metadata tagging and license inclusion to ensure reproducibility. - Tekton-based CI/CD for go-httpbin: PR and master build automation with multi-arch capabilities, enabling faster, more reliable releases. - Konflux compliance and metadata improvements: standardized tagging, licensing, and reproducibility controls across the image builds. - Release automation and build performance: reduced build times and more consistent image artifacts, enabling faster deployment cycles and improved delivery reliability.
