May 1, 2025Summary for 2025-05: Delivered key features and upgrades for rhobs/konflux-coo, focusing on reproducible builds, cross-architecture compatibility, and upgrade readiness. Implemented Hermetic Builds across Tekton pipelines for Thanos, Alertmanager, and COO bundle by moving hermetic build params to spec and enabling hermetic mode, with refined build platforms/storage. Updated UBI 9 base image references to source mailcap and dependencies for perses-operator across architectures. Upgraded COO to 1.2 including image references and submodule bump. Upgraded perses-operator build/config to v0.1.12 for Go 1.23. These changes reduce drift, improve CI reliability, and position downstream consumers for smoother release cycles.

Apr 1, 2025April 2025 monthly summary focused on delivering reproducible, hermetic builds for Thanos within the Konflux CI/CD framework to improve build reliability, reproducibility, and deployment confidence. The major feature delivered was Thanos Hermetic Build and Reproducible CI in Tekton pipelines, enabling prefetching of Go modules and activating hermetic build mode in PR and push pipelines. The Dockerfile was updated to use a direct Go build command for a more controlled, deterministic build environment. A single commit (626f517cf9357ce09426d5bade256da9bbf8f99b) titled 'Enable hermetic builds in Thanos' was introduced as part of these changes and integrated into the PR/push pipelines. No major bugs were reported or fixed this month; the focus was on feature delivery and process improvements. Overall impact includes more reliable and reproducible builds, faster PR validation, and a lower risk of flaky CI outcomes. Technologies/skills demonstrated include Tekton CI, Go module management, hermetic/deterministic builds, Docker build optimizations, and CI/CD pipeline tuning.

Dec 1, 2024December 2024: Key focus on expanding build capabilities, pipeline reliability, and CI efficiency for rhobs/konflux-coo. Delivered multi-architecture build support for FBC pipelines (x86_64, arm64, ppc64le, s390x) with platform parameters, updated task references, and OCI-TA compatibility. Improved Tekton Pipeline triggers reliability and default configurations, addressing misconfigurations, expanding trigger capabilities, and adding OCI storage parameters. Fixed Core FBC Release and CEL/OCP version issues affecting push triggers and mintmaker-related registry behavior by correcting CEL expressions and version parsing. Enhanced CI efficiency by gating catalog rebuilds on relevant changes and performing cleanup such as removing trailing spaces in image/UI references. These changes reduce build times, prevent unintended updates, and enable safer, multi-arch deployments.
