April 2026 monthly summary for percona-helm-charts (repo: percona/percona-helm-charts). Focused on reliability and clarity for PMM updates deployment. Delivered a critical bug fix to PMM_ENABLE_UPDATES parsing by changing its type from integer to string, updated documentation to clearly describe the option and its effect on periodic checks and UI upgrades, and reinforced release readiness with CI/CD workflow improvements, RC image testing, and deployment stability measures. These work items reduce misconfiguration risk, improve upgrade checks, and contribute to more stable, predictable releases for customers.

Month: 2026-03 Overview: This period delivered two focused features across two repositories that improve privacy, governance, and deployment control in PMM. All work is aligned with business value of reducing data exposure and giving operators deterministic release management in Kubernetes environments. Key features delivered: - Privacy-preserving Telemetry in PMM3 server builds: Disable telemetry collection when the Docker RC tag is not set, enhancing user privacy and regulatory compliance. Commit: 0593f4a6646fa8363719602190e705daf9d3e49e (PMM-14825). - PMM Deployment Versioning and Update Policy in Helm charts: Update to PMM 3.7.0 and disable automatic version checks to ensure manual control of updates in Kubernetes environments. Commits: f5dbcdd0f3c381b25562466cf1e28dc98b169068 (Release PMM 3.7.0); 514eb1527c6ecf2146bd62fc5720e07abe193bca (Disable periodic PMM version updates in values.yaml and README). Major bugs fixed: - No high-severity bugs closed this month. The work focused on feature delivery and governance improvements that reduce privacy risk and improve update control. Overall impact and accomplishments: - Enhanced privacy and regulatory compliance for PMM server builds by suppressing telemetry when appropriate. - Improved deployment governance in Kubernetes environments through explicit PMM versioning and manual update controls, reducing unintended updates. - Strengthened release management practices with explicit versioning and documented policies across Helm charts. Technologies/skills demonstrated: - CI/CD and build pipeline hardening (privacy controls in build workflows) - Docker tagging awareness and conditional feature toggles - Helm chart versioning and deployment gating - Kubernetes update governance and release notes/documentation updates - Release management, versioning discipline, and cross-repo collaboration

February 2026 monthly summary focused on PMM 3.6.0 release deployment in percona/percona-helm-charts. Delivered a coordinated release of the PMM 3.6.0 with updates across Docker image, PMM server image tag in the Helm chart, and Helm chart versioning to reflect the new application version.

January 2026 monthly summary focused on delivering stable, secure, and scalable improvements across Percona Helm charts and Percona Backup for MongoDB. The work highlights operational efficiency, reliability, and security enhancements that drive business value through smoother deployments, faster test cycles, and hardened security posture. Key features delivered: - PMM database creation workflow implemented via an initContainer and a Kubernetes Job, with updated readiness checks and image tag adjustments; aligns deployment bootstrapping with automated initialization and improved reliability. - Replica count and resource management optimizations: reduced and then restored replica counts to optimize test speed and deployment stability, alongside aligning pmmResources to avoid resource overconsumption. - CI/test infrastructure improvements: pipeline reliability enhancements including trying a different image and more deterministic test triggering to reduce flakiness and shorten feedback loops. - Anti-affinity handling improvements for haproxy and other pods: enabling/disabling and resetting anti-affinity, plus removal of anti-affinity configuration in CI values to improve test determinism. - Security hardening in Percona Backup for MongoDB: CVE-2025-61729 remediation through dependency updates and cryptographic library improvements for better security and compliance. Major bugs fixed: - Contributor email metadata corrected in commits to ensure accurate attribution. - Fix for wrong pmm.resources parameter to prevent misconfiguration and resource misallocation. - Helm install robustness improvements addressing install-time failures to ensure smoother deployments. - General anti-affinity related fixes to prevent flaky pod scheduling and improve stability. Overall impact and accomplishments: - Reduced deployment flakiness and improved test reliability, enabling faster feedback and more predictable rollout of charts and backups. - Improved security posture through proactive vulnerability remediation and dependency hygiene. - Achieved better resource efficiency and performance tuning, especially for ClickHouse and PMM components, contributing to lower cost and higher capacity. Technologies/skills demonstrated: - Kubernetes primitives (InitContainers, Jobs, anti-affinity settings), Helm chart customization, and chart version management. - CI/CD pipeline optimization, test orchestration, and image lifecycle management. - Security best practices, vulnerability remediation, and dependency updates. - Resource and capacity planning with memory/resource tuning for high-demand services. - Attention to detail in metadata hygiene and configuration correctness for operational excellence.

Monthly Summary for 2025-12: Delivered core stability and deployment reliability improvements in percona-helm-charts. Implemented comprehensive image tag updates across components with related housekeeping, enhanced high-availability resilience, and hardened anti-affinity policies for critical PostgreSQL components. Performed repository cleanup to reduce maintenance surface (docs removal, config cleanups, and maintainers update). Reverts of non-critical changes were applied to restore a stable baseline and support safer upgrades. These efforts reduce deployment risk, improve CI/CD consistency, and deliver measurable business value through more predictable upgrades, faster recoveries, and stronger resource isolation.

November 2025 monthly summary: Focused on security improvements, deployment reliability, and observability enhancements for the PMM Helm chart. Implemented secure-by-default defaults (HTTPS and readiness checks), deployment simplifications, and VictoriaMetrics VMAgent integration, delivering business value through reduced risk and improved metrics coverage.

September 2025 monthly summary: Focused on refining governance accuracy in Helm charts. Delivered a targeted maintainers roster update for percona/percona-helm-charts by removing spron-in from Chart.yaml to ensure the maintainers list reflects current contributors. No major defects fixed this month. This adjustment strengthens contributor attribution, clarifies ownership for releases, and supports automated tooling that consumes chart metadata. The change is fully traceable via the commit 905cee6ddac7ff519dfd0ddc63a39de5f4865106, aligning chart metadata with actual contributions and reducing release-risk.
