Worked on modernizing Jenkins deployment within the DaoCloud/dce-charts-repackage repository by upgrading the Jenkins Helm chart to versions 0.4.5 and 0.4.6. Focused on ensuring consistent and reliable deployments by updating all related version references across main chart configuration, image definitions, and agent builder versions. Used YAML to manage configuration changes and leveraged DevOps practices with Kubernetes and Helm Charts to centralize version management. Documented upgrade changes and validated consistency across chart files to prevent configuration drift. The work improved maintainability and ensured that the deployment process utilized the latest stable chart and components without introducing breaking changes.
