Worked on the DaoCloud/dce-charts-repackage repository to enhance release readiness and chart maintenance by upgrading the cert-manager Helm chart from version 1.16.1 to 1.16.4. This update, implemented through changes in Chart.yaml and values.yaml, enabled access to newer features and security improvements, supporting improved deployment stability and easier future upgrades. The work focused on aligning the Helm chart with current Kubernetes capabilities, ensuring downstream deployments benefit from enhanced maintainability. Leveraged DevOps practices and expertise in Kubernetes and YAML to deliver this feature, with an emphasis on supporting ongoing chart evolution and maintaining compatibility with the latest ecosystem standards.
