April 2025 (percona/percona-docker) — Monthly summary focused on deliverables, stability, and business impact. Key features delivered: - Architecture-aware Dockerfiles for percona-pgbackrest and percona-pgbouncer: Dockerfiles updated to fetch architecture-specific PostgreSQL 17.4 release packages, improving cross-arch reliability. - Release-channel stability: Default package source switched from testing to release to ensure deployments pull from the stable channel. Major bugs fixed: - No major bugs reported or fixed in this period. Impact and accomplishments: - Improves deployment reliability and predictability across architectures, reducing runtime failures due to mismatched packages. - Aligns image provisioning with enterprise stability goals by using the stable release channel. Technologies/skills demonstrated: - Dockerfile modernization and multi-arch packaging - Release-channel management and version pinning - Commits tied to PKG-561 for architecture and release changes (ec55f2688202a6497de5a8a83736fa900ea97026; 5aee0b6aa4f68c7f9b39cac17b4973077fc3a15b) Top 3-5 achievements: - Architecture-aware packaging for two key images - Stable-channel defaulting for deployments - Clear linkage to PKG-561 commits for traceability

February 2025 monthly summary: Focused on automating PostgreSQL tarball creation and keeping docker images current to accelerate validation and deployment. Key features delivered include an automated Groovy-based CI workflow to build PostgreSQL source tarballs for versions 13-17, upload artifacts to a testing server, and standardize artifact naming while removing the obsolete PG12 build stage. In parallel, Percona Docker images were updated to the latest minor PostgreSQL versions across 13-17, with environment variables PPG_VERSION and PPG_MINOR_VERSION updated in relevant Dockerfiles. These changes reduce manual toil, improve artifact reliability, and ensure teams can validate against current PostgreSQL releases quickly. Overall, these efforts improve release readiness, security posture, and supportability by keeping CI artifacts and images up-to-date. Technologies demonstrated include Groovy/Jenkins pipelines, artifact management, and Docker image maintenance.

In January 2025, focused on stabilizing runtime environments and CI/build pipelines across core Percona projects. Delivered fixes to PMM agent startup/uninstall logic, implemented robust multi-architecture tagging and manifest handling for Percona container images, and ensured runtime reliability through consistent timezone data and package retrieval improvements in Docker images. These changes improve deployment reliability, cross-architecture support, and overall product quality with clearer packaging workflows.

December 2024 monthly summary focusing on concrete deliverables, business value, and technical achievements across two primary repos. Highlights include improvements to CI/CD pipelines, Docker image reliability, base image modernization, and feature enablement with configurable toggles. Also notes a targeted rollback to preserve stability where needed.

November 2024 monthly performance summary focusing on delivering automated, high-value CI/CD for PostgreSQL deployments and expanding capabilities with vector search. Key initiatives included an end-to-end Nightly CI pipeline for PostgreSQL 17+ with pg_tde and PostGIS packaging, and extending Percona Docker images to include pgvector across multiple versions and architectures. The work enhanced build automation, artifact management, and image readiness for production deployments, while improving reliability and alignment with upstream changes.
