October 2025 performance summary focusing on CI stability, cloud-native deployment readiness, and test reliability across Percona pipelines.

September 2025 monthly summary focusing on key accomplishments across two repositories: Percona-Lab/jenkins-pipelines and percona/pmm. The month delivered expanded OS support, dynamic tarball capabilities, and cleanup improvements in CI/build pipelines, enabling deployment on RHEL 10, AlmaLinux 10, Debian 13, and Oracle Linux 10, with improved packaging and artifact generation.

August 2025 monthly performance summary for Percona-Lab/jenkins-pipelines: Delivered two major features that enhance platform compatibility and secure distribution. First, Debian Bullseye support was added to Jenkins build pipelines, including new AMI and user mappings, multi-arch (amd64/arm64) build configurations, an updated apt update flow for Bullseye, and client binary builds targeted at Bullseye. Second, private PMM3 client tarball distribution was enabled via the release pipeline, with build scripts updated to use environment variables for dynamic tarball URLs (OL8/OL9) and a dedicated release stage to securely upload tarballs to percona.com. These changes simplify deployment for Bullseye-based environments and streamline private client distribution while improving security and traceability.

July 2025: Focused on packaging automation, CI/CD modernization, and pipeline reliability across PMM projects. Delivered cross-OS client tarball packaging, upgraded Jenkins to Amazon Linux 2023, and enhanced Python interpreter handling and OS-specific tarball builds, improving deployment accuracy and release velocity.

June 2025: Focused on improving build reliability, OS lifecycle management, and CI/CD efficiency across PMM and Jenkins pipelines. Key work included: 1) Automated pmm3 Client Autobuild Reliability: improved Dockerfile/build environment for EL8 rpmbuild to create Go module cache and build artifacts, enabling reliable automated pmm3 client builds. 2) Server Build Stability: Enforce Python 3 for Ansible: switch default to /usr/bin/python3 to prevent Python 2-based failures in server Docker builds. 3) Streamline Build OS Support: drop Ubuntu Focal and Debian Buster, default to Ubuntu Jammy to simplify maintenance and improve compatibility. 4) Packer Version Compatibility: revert to 1.9.4 due to build issues with newer Packer. 5) CI Build System Modernization (jenkins-pipelines): remove support for Ubuntu Focal and Debian Bullseye from build pipelines to align with current supported distributions.

Monthly summary for 2025-05: Key features delivered: - PMM Client Build System Modernization and Optimization: Standardized build environment with Oracle Linux 8, migrated package management from yum to dnf across Ansible roles and Dockerfiles, and optimized the pipeline with Docker build cache mounts to reduce build times.

Commit: b4158ca0d8f9f1dc89ace682caf5292bcabbd588. - Build and deployment environment modernization (Oracle Linux 8 build support; YUM to DNF migration): Consolidates build and pipeline improvements by adding OL8 support for pmm-client builds with a new rpmbuild tag for OL8 and migrating CI/CD scripts from YUM to DNF for compatibility with latest RHEL-based systems. Commits: 5d42ee7f5c1dc826aaa6e3a6578dc74a4ce94383; c4252ef97ac05f771e88dec17ace2124c61d7976. Major bugs fixed: - No explicit bug fixes recorded in this dataset. Improvements in reliability and performance are achieved via build system modernization, cache optimization, and increased provisioning capacity, contributing to fewer build-time failures and shorter pipeline times. Overall impact and accomplishments: - Faster, more reliable builds with standardized OL8-based environments across two repositories, enabling easier maintenance and cross-repo collaboration. - Improved CI/CD readiness for OL8/RHEL-based systems, reducing time-to-build and increasing pipeline throughput. - Increased workspace capacity mitigates bottlenecks in large workflows and artifact handling. Technologies/skills demonstrated: - Docker, Oracle Linux 8, dnf, Yum-to-Dnf migration, Ansible, Docker build cache mounts, AWS Packer configurations, rpmbuild OL8 tagging, and CI/CD scripting modernization.

April 2025 performance summary focused on delivering security hardening for Nomad access, a Lambda runtime upgrade, and a PMM ClickHouse log retention adjustment. No critical bugs reported; security, stability, and storage optimizations were completed across two core repositories, delivering measurable business value and demonstrating strong execution in infrastructure and data layer management. Impact highlights include improved security posture for Nomad workloads, updated Lambda runtime for maintainability, and reduced log footprint in PMM ClickHouse, helping to control storage costs and potentially improve query performance.

March 2025 was focused on strengthening security, reliability, and enterprise readiness across PMM and CI pipelines. Key improvements include RPM packaging and build environment upgrades enabling Kerberos integration and Amazon Linux 2023 support; PMM client image enhancements to install Perl and broaden MySQL-related configuration; stabilization of the OVA build pipeline; and security hardening with 4096-bit Diffie-Hellman parameters for OpenResty across environments. CI/agent provisioning improvements also enhanced deployment reliability. Collectively, these efforts reduce risk, improve build stability, and accelerate enterprise deployments while expanding platform support.

February 2025 monthly report focusing on reliability and security improvements across release pipelines and PMM images. Implemented key fixes to release tagging, artifact paths, OVA image cleanup, and PMM client image packaging to reduce build failures and shorten release cycles. Delivered two major pipeline improvements and three image/build hardening changes that collectively decrease risk in production deployments.

January 2025 focused on release pipeline hardening, artifact traceability, and targeted deployments. Delivered Watchtower integration and tagging standardization across Jenkins pipelines with an autobuild release trigger, enabling consistent builds and faster delivery. Added PMM Watchtower image release support for targeted deployments in the PMM workflow. Enhanced PMM client image packaging with metadata labels, version metadata, and Perl dependencies for better traceability and compatibility. Streamlined pipelines by removing redundant yum update steps in aws-staging-start, reducing build time and risk of conflicts. Strengthened release artifacts accuracy by ensuring versioned client paths and correcting the rsync deployment target IP. Overall impact: more reliable, faster releases with clearer auditability and improved deployment precision; demonstrated proficiency in Jenkins, Docker image packaging, release automation, and deployment scripting.
