May 2025 monthly summary for cloud deployment and helm-chart domains. Key outcomes include chart and deployment enhancements, platform upgrades, robust secret management, and targeted bug fixes across two main repositories. The work delivered improves deployment reliability, security, and developer velocity, with concrete steps across environments (dev, staging). Key features delivered: - stfc/cloud-deployed-apps: - Added dev chart, pointed configuration to Harbor chart, and switched to alpha chart for materials-galaxy; ensured staging uses cloud-helm-charts and dev uses the released chart. - Re-enabled the changed-files GitHub Action, performed code cleanup (removing an unnecessary comment) and addressed linting concerns. - stfc/cloud-helm-charts: - Implemented git-sync-based tool cloning for Materials Galaxy; updated tool paths; improved init-container docs; simplified configuration, removing unnecessary extraVolumes. - Fixed Kubernetes templating for repository deploy keys secret; improved cluster configuration (cert-manager troubleshooting guide, storage class secret namespace changes). - Upgraded the OpenStack-backed Kubernetes cluster to 1.32.4 and updated the machine image accordingly. Major bugs fixed: - Harbor configuration fixes and pathing to shared secrets; change GITSYNC_BRANCH to GITSYNC_REF; Longhorn staging infrastructure bug fixes (ignorediff handling, stage chatops adjustments, and app deployment tidy-ups); templating and formatting fixes for staging shared-values. Overall impact and accomplishments: - Increased deployment reliability and environment parity (dev, staging) through chart improvements, secret rotation automation, and platform upgrades. - Strengthened security posture via structured secret rotation for staging, workers, and app credentials; Harbor secrets update. - Improved developer experience and maintenance through CI automation, linting improvements, and clearer documentation and troubleshooting. Technologies/skills demonstrated: - Kubernetes, Helm charts, Argo CD, git-sync, Harbor integration, cert-manager, storage class management, templating, OpenStack-backed Kubernetes upgrades, and GitHub Actions (CI) for lifecycle automation.

April 2025 monthly summary focused on delivering stable Helm-based deployments, improved release readiness, and maintainability across two repos: stfc/cloud-helm-charts and stfc/cloud-deployed-apps.
