Worked on upgrading the MapGL library to version 1.67.0 within the 2gis/on-premise-helm-charts repository, focusing on enhancing feature parity and maintainability for on-premise deployments. The update involved modifying Helm chart definitions in Chart.yaml, updating configuration defaults in values.yaml, and synchronizing documentation in README.md to ensure accurate guidance for users. Leveraged DevOps practices and expertise in Kubernetes and Helm, using YAML as the primary configuration language. The work improved compatibility and default behaviors across environments, ensuring that the deployment process remained robust and aligned with the latest library requirements. No bugs were reported or fixed during this period.
