Worked on the 2gis/on-premise-helm-charts repository to address deployment reliability for the Mapgl JavaScript API. Focused on ensuring that the correct API version, specifically v1.56.0, was consistently deployed across all environments by updating Helm chart configurations. Utilized DevOps practices and Helm templating, making precise changes to Chart.yaml and values.yaml files written in YAML to align the deployed appVersion and image.tag with the supported API version. This fix eliminated version drift and improved traceability for future updates by linking the relevant commit, resulting in more predictable deployments and easier auditing of changes within the on-premise deployment workflow.
