February 2025 monthly performance summary for kogito-pipelines and kie-tools. Focused on delivering reliable CI/CD improvements, pipeline modernization, and security hardening to enable faster, more predictable software delivery and reduced operational risk. Key features delivered and major improvements: - DB Migrator Tool in Production Nightly: Introduced DB Migrator Tool image in the production nightly build pipeline with new environment variables and a dedicated build stage, enabling smoother database-related migrations in nightly releases. - CI/CD tooling upgrades and pipeline migration: Upgraded upload-artifacts to v4 and aligned the nightly build pipeline with the updated operator image source (due to deprecation), improving build reliability and maintainability. - Remove CI artifacts archiving from PR builds: Removed archive-artifacts from PR CI config to reduce log noise and storage usage, streamlining CI workflows. - Security hardening: Update Go to 1.22.12 across build and environment (Dockerfiles, GitHub Actions, README, and lock files) to address disclosed CVEs and strengthen security posture. - CI Build Artifacts Handling - Bug Fix: Fixed artifact mapping and MD5 caching in the OSL nightly build process; correct handling of Cekit overrides and artifact definitions, improving artifact reliability and traceability. Overall impact and business value: - More reliable nightly and PR builds with accurate artifact handling, reducing deployment risks and post-build troubleshooting. - Modernized CI/CD tooling and pipelines reduce maintenance burden and errors from deprecated sources. - Strengthened security posture across the development environment, reducing exposure to known CVEs. - Clearer visibility into builds and artifacts, enabling faster decision making and release readiness. Technologies and skills demonstrated: - Go runtime updates and security hardening; Dockerfile and environment management; GitHub Actions workflow adjustments; artifact management and MD5 caching techniques; Cekit overrides handling; pipeline migration and maintenance; observability and build traceability.
