September 2025 monthly summary for Percona-Lab/jenkins-pipelines focused on delivering robust OpenShift cluster creation and deployment workflows and strengthening CI/CD tooling. The work reduces manual steps, improves deployment reliability, and enhances security posture across environments, with clear business value in faster, more secure releases and better operational visibility.

Delivered OpenShift cluster lifecycle management in Jenkins pipelines, including create/destroy/list operations, shared lifecycle libraries, and S3-backed state persistence with a PMM deployment. Migrated AWS operations to AWS CLI to improve Jenkins compatibility and reliability. Updated CODEOWNERS to assign @Percona-Lab/build-engineers for PMM/CD areas, streamlining reviews. Fixed OpenShift cluster discovery by implementing a two-pass S3 backup name matching and enhanced summary reporting. Enhanced Jenkins job descriptions to surface OpenShift/PMM details with direct URLs and credentials. Won't-splat: addressed Jenkins pipeline sh step deprecation warnings by replacing env with withEnv and refactoring for reliability. Business impact: faster provisioning, higher reliability, improved operational visibility, and stronger governance across PMM/CD IaC; demonstrated expertise in Jenkins, OpenShift, AWS CLI, PMM, and IaC patterns.

July 2025 monthly summary for percona/pmm: Delivered a Hetzner-optimized Docker-based Rocky Linux 9 RPM build setup, including Dockerfiles for rpmbuild on Rocky Linux 9, European mirrors to accelerate downloads, and new Makefile targets with conditional logic to leverage the Hetzner-specific Docker image. This work enhances build performance, reproducibility, and deployment readiness across European infrastructure.
